Methanol wall wash test is performed to determine the cleanliness and suitability of cargo tanks or compartments on a marine vessel prior to loading of high quality requirement like polyester grade monoethylene glycol.

Product Description: 

Significance and Use

The methanol wall wash test is performed to determine the cleanliness and suitability of cargo tanks or compartments on a marine vessel prior to loading of high quality requirement like polyester grade monoethylene glycol. As it is adversely affected by oxygen, hydrocarbons, water and chloride. It is especially susceptible to aromatic contamination, which degrades UV transmittance. Possible sources of contamination are the prior cargoes and cleaning agents. The methanol wall wash procedure provides a representative sampling of the impurities and contamination present on the sides of the cargo tank.

 

This test method covers the methanol wall wash procedure and the chemical and physical analysis of the wall wash sampling for cargo tanks of marine vessels handling polyester grade monoethylene glycol. 

The methanol wall wash procedure provides a representative sampling of the impurities and contamination present on the sides of the cargo tank. The test methods used for analysis of the methanol wall wash samples are capable of determining low levels of impurities or contamination in methanol. These tests include appearance, color, hydrocarbons and chloride.

The producers of sensitive cargo like polyester grade monoethylene glycol need confirmation of the cleanliness and suitability of the marine vessel’s tanks prior to loading with in-specification material. Cargo tanks that do not pass the wall wash test should not be loaded.

Product Procedure: 

This text contains is a typical procedure used on one of my previous ships to convert from high brix (93) Columbian Molasses to MEG fibre grade for UCC.

Olefins, Pthalates, Adipates, Fatty acids and Fatty alcohols are bad previous cargoes for next wall wash cargoes.

Wall wash test for Mono Ethylene Glycol fibre grade is the most stringent.

When you take a wall wash ensure the tank is perfectly dry ( especially zinc coated tanks ). There can be no sea spray as WWT is a weather permitting procedure especially for MEG (fg) where chlorides fail for union carbide corporation at 0.249 ppm. Tell master to alter course during ventilation and wall wash. FW rinse area around tank entrance to remove salt from sticking to shoe cover. Suspect like a paranoid moron that every thing that the methanol comes in contact with , till you write down the results could be dirty . Do not be stingy with lab methanol. Ensure your sweat drop does not alter results.

Wallwash is taken from 4 parts of all 4 bulkheads—but not from corners,which do not count as a standard value. Surveyors must be accompanied inside tanks by a responsible person.

For Wall Wash take into the tank one litre of Methanol. Only 200 cc 1/5 of this amount is brought out for testing. After filling up squirt bottle with methanol, analyse for HC and CL first before taking into the tank.

WWT surveyor must not wash more than 6 feet height. He also cannot wash the bottom unless you are loading Hexene 1/ potable Ethanol etc.. Floor areas are tested by placing ( not wiping ) filter paper on a spot wetted by Methanol. This paper is placed inside a sample bottle and 50 cc test Methanol is added for every piece of filter paper. If any surveyor wipes bulkheads with Methanol soaked instead of squirting Methanol using a polyethylene squirter , tell the master as this is not a representative sample of the action of liquid on the bulkhead .

Methanol spray by crew to beat the surveyor is not a bright deed in the context of MEG FG as all you do is to bring the dirt from sides to bottom. So mop bottom sides with sponges and DI water. No rags are allowed as more than 10 suspended particles in the first foot sample fails for MEG FG. Use torch beam at zero incidence in a dark tank to detect lint shed from paper shoe covers.

Various tests done all over the world are---- (remember all of them may not be applicable to your cargo, so find out well in time. The main ones are HC, CL and PTT. )

1)Visual first impression
No condensation moisture on cold interface bulkheads or deck head,no blistered or open splits on epoxy coating, no white coloured patches of Zinc salts or Calcium and Magnesium sea water salts , no black rouge Fe3O4 tattoed into stainless steel active surfaces from oxidised welds, no red Fe(OH)3 due to boiler water alkaline additives etc, no green vitriol Ferrous Sulphate patched on stainless steel active areas. Use Bufferclean Citric acid of pH 5.5 to remove salts from zinc tanks and adsorbed ( this is a surface phenomenon in zinc tanks and is different from absorbed ) previous cargo reactant matter. Dye out is an organic stain remover.

2)Odour of tank
Meg is odour absorbing . Use lac to remove odour in SS tanks. Acrylates have their own smell killers like Monoethanolamine and air fresheners marketed by tankcleaning chemical companies. After a strong smell cargo if the next cargo is odor sensitive the seals of tank dome / butterworth ports may have to be exchanged. Pyridine cargoes give very strong odour.

3) Colour of Methanol wash
Colour 5 Apha (or Saybolt ASTM D12095) is required for the MEG fg wash ( highest spec.) . Must see in day light or fluorescent light against a white sheet of paper at night. Use the magnifying glass or even your reading glasses

Apha solution is platinum chloride solution. The number of cc Apha solution ( min is 5 cc ) for Apha 5 added to distilled water gives the shade number.

Lightest is +30 Saybolt and darkest is -16 used only in the petroleum industry. Water White standard colour is in the range of +30 to +20.

Apha zero means clear. In your wall wash lab you must have comparator nessler tube ready made solutions of A5 A10 and A20 ( always in multiples of 5 ).

The standard apha solutions are stable for many days but should be done again after one week. The stock solution is stable for an indefinite period if kept in a refrigerator.

Proforma: ml of 500 APHA Stock Solution Diluted to 100 ml with Distilled Water/ APHA number
1/5
2/10
3/15
4/20
Slightest colour in previous cargo can cause untold problems with wall wash of zinc tank. Don’t allow dyed CPP unless you are looking for big trouble. However dye out bleach can be used to remove dye of gasolenes.

4)Suspended matter in wash:
Check in a dark room , against black background. Shine thin beam torch from bottom of a round bottom tube . MEG fg WWT fails with a single suspended particle. For first foot it is ten. Particulate matter which sink to the bottom is not a cause of failure for MEG fg.

Remember colloidal particles readily pass through ordinary filter papers. Animal membranes can hold them.
The path of light through a colloidal suspension is called a Tyndall cone.

Filter papers are made of particular pore size by impregnating ordinary filter paper with colloidal particles. Colloids may be coloured or transcluscent due to Tyndall effect. Tyndall effect is the scattering of light by particles in the colloid.

5) Chlorides

UCC wants 0.249 ppm for pass. Black back ground check with torch from under. Ashore done by gas ion chromatographs. Lab methanol is tested to 0.100 ppm chloride by ion chromatography. Method used for separating dissolved substances by partition or aDsorbsion is called chromatography.

Photospectrometer and conductivity meter can be used on board. The Whatman #42 filter paper used prior chloride test is chloride free and ashless. If you don’t have a good filter paper leach it with lab methanol.
Glycols, Methanol and Ethanol are very sensitive to contamination by chlorides.
It is MOST important to run both wash samples and standards solutions simultaneously and view them together as the silver chloride turbidity produced continues to undergo a photochemical reaction.
Use pipette bulb, do not pipette by mouth.

6) Hydrocarbons
Found out by looking for time taken for bubbles to disappear or foam on top. Now this foam could be old Genepol extracted from pores by methanol in a zinc tank. If previous cargo is insoluble in water HC WWT may fail. So use HC free cleaner to pass the HC test.. This test can be called water mixibility test. Can be shaken 1:4 (not strict ) or 1: 2 ( very strict ). In Kuwait they overdo it and do 1:1.

When a light beam is used it is called Tyndal test. Methanol is very sensitive to oil contaminants. Light beam is deviated by HC contaminants . Turbidity ( milky emulsion )is a measure of refraction of the liquid. No beam means HC free. Faint white beam means 1 ppm HC. Blue beam means excess of 2 ppm. Remember blue colour of sky is due to the scattering of light by colloidal particles of dust in the air and not due to HC.
Methanol is very sensitive to oil contaminants.
Celanese report HC as ppm n-Heptane. They make various standard solutions by mixing n-Heptane with Methanol and water.
Some rubber and plastic release HC. So only approved equipment should be used.

In many ports the HC test is pass or fail, no attempt is made to estimate quantity of hydrocarbons as the turbidity produced depends on the actual hydrocarbon . This is because certain chemicals like L A B (linear alkyl benzene) give turbid solutions at very low ppm concentration whereas Toluene and other aromatics require extremely high concentrations before it can be detected .
After a failed WWT it is good practise to rinse the tube several times with water/lab methanol with the use of a bristle brush.

7) PTT
Look down into tube kept in a cold 15C water bath of white colour in daylight or fluorescent tube light. Low PTT is often the result of a reducer remaining on the tank surface which could be the cargo itself.Bleach is known to be contrary to a reducer and is an oxidising agent. Recirc at 50 deg after opening the pores of the coating. Wash old PTT tested glass in HCL, then water and then Methanol. The pinkish purple of the Potassium Permanganate solution changes to straw yellow ( Manganese di Oxide ). Extreme of pH can interfere with test. Check every 5 minutes . PTT test detects all inhibited chemicals. Make new KMNO4 solution every 3 days and store in an amber coloured bottle.Under purest condition PTT test will run for 120 minutes. PTT test fails only when contaminants react with KMNO4. HC does not react with KMNO4. So PTT time can be increased by Bleach or Chlorinated solvents . An equivalent of Stolt X is marketed by chemical companies too to neutralise the effects of Acrylic Monomers.

To get the true color of the faded straw yellow a standard solution of platinum cobalt (Uranyl Nitrate ) is available in the market.

The Potassium permanganate solution should be stored in brown bottles and in the dark.
Even if the PTT test taken on board before arrival passed, gives no quarantee to have the same result from the surveyors test. (Different spots taken by surveyor).

Glass apparatus that have a `brown film' should not be used as it is Manganese di-oxide, the reduced product of potassium permanganate. This will catalyse the oxidation/reduction decolorisation process of potassium permanganate and will give less PTT time. Glassware is cleaned by overnight immersion in an acid bath of 50% hydrochloric acid. The clean tubes must then rinsed well in tap water followed by DI water / Methanol.

Similarly, the flask containing stock solution of potassium permanganate requires cleaning between batches of fresh solution. The last rinse should be with fresh potassium permanganate solution and not methanol.

Uranyl nitrate is HIGHLY TOXIC. This substance must not come into contact with the skin and NEVER be pipetted by mouth. Treat the Uranyl nitrate/ Cobaltous chloride standard solution with care.

8) NVM :
To determine the weight of residue left on the surface. Spray Acetone / Hexane on a small area. If sprayed area has a visible boundary ( bur n marks ), non volatile matter is there. NVM consists of high BP sediments, dirt, rust etc.
Ashore it is done by evaporating the Methanol wash and weighing.

9) pH:
Ph value greater than 9 ( boiler alkaline additive ) in the pipelines will cause the MEG fg deslopping contents to take the tinge of Venetian red. For certain cargoes like Phenol the pH test is check for acidity.

10)COD test: chemical oxygen demand test. The impurities are extracted by methanol and analysed with an oxidiser like Pot Dichromate.


Procedure-
After a prolonged hotwash allow the tank to rest prior doing wwt.
Go to tank and collect 200cc of wash in a clear bottle. To achieve this you must squirt at least 500 cc from a polyethylene squirter to allow for spillage. Never miss the leading edge of dirty wash flowing down the wall. Make your own funnel by slicing off a Polyethelene bottle with an extremely sharp box cutter blade. Mate it on a porthole glass pour methanol and see it does not spill even a drop. The neck of this funnel must lead direct into the sample bottle ( narrow neck ). With a gloved hand you must be able to hold both, the other hand for the squirter.When you dispose wash Methanol in CCR sink run the water tap as a safety measure lest it gasses up a sleeping seaman in a cabin.
Always use same pipette for each lab ingredient, do not change. Wash funnel after each use inside the tank—make SURE. Use parasol to prevent salt spray ingress into tank.

HC test:
25cc wash plus 75 cc distilled water in a stoppered tube. Shake vigorously and stand. Come back after 20 minutes and if there is foam layer on top test has failed. To pass it must look like distilled water. For places like Kuwait the HC test is so strict that it is better to use 1:1 ratio. If you shine a torch beam from the side it must not look blue.
Ashore they qualitatively filter the wash using 5A filter paper or Whatman 42 after leaching the paper with Methanol to remove industrial paper chlorides.

Chloride test:
50cc un-filtered wash add to 30 cc distilled water shake well to dissolve salt and then filter qualitatively.
Colloidal particles are not simple molecules but physical aggregation of molecules . They readily pass through ordinary filter paper.. Turbidity is a measure of the refraction of the liquid. Colloidal matter indicates hydrocarbons, chlorides and other residues.

Note: Methanol cannot dissolve salt or loosen the sodium cation/chloride anion from the NaCL ionic bond. -only water with high solvent power and high dielectric constant can do this. NaCL crystal is extremely strong and rigid. A Sodium ion is equally attracted to 6 Chloride ions.
To this 80cc mixture--- add 1/2 cc silver nitrate( strength 10%) plus 2cc nitric acid ( strength 20%) plus 17.5 cc di water to make 100 cc total.
Shake and stand for 5 minutes. Compare milkiness with a standard comparator of 1ppm made as follows:
50cc Methanol + 4cc standard Chloride soln ( strength 10ppm ) + 1/2 cc Silver Nitrate ( strength 10%) + 2cc Nitric acid ( strength 20%) + 43.5 cc DI water to make total 100cc solution . Memorise this milkiness as the failing standard for the current voyage.
(for 0.5 ppm comparator put 2 cc of standard chloride soln, for 0.250 ppm put 1 CC.) For 2 ppm put 8cc NaCl ----for 4ppm put 16cc NaCl.

Why Nitric acid ??--- Nitric acid parts the silver vide the assaying process as chemically silver is not active and dissolves only in strong Nitric acid or H2So4.
The method of not involving Nitric acid in the Chloride test could pass a ship staff tank WWT , while a shore gas ion chromatograph will fail the sample for Mono Ethylene Glycol fibre grade. Nitric acid decomposes Sodium Cyanide and Sodium Sulphide which otherwise form precipitate with AgNO3 and thus interfere with the lab test.

KMNO4 PTT test---
It is easy to fail this test if gasolene dye fillers / cutters or inhibitor chemical is present.
Hydrocarbons do not react with KMNO4.
50cc filtered wash + 2cc KMNO4 ( 0.02 % strength ). Mix 0.1 gms of the solid in tube to 500 cc of di water to get 0.02% strength. It takes 1.5 hrs for the KMNO4 crystals to dissolve. The pot life is only 3 days so keep it in the fridge in a amber coloured bottle. Keep in a dark place at 15C.Note the time taken for the purple pink colour to change to straw yellow .Must hold for 50 minutes in the bath of 15C in a dark place. Check every 5 minutes.

Use HCL, then DI water, then Methanol to wash glass , then water and finally Methanol. Under the purest conditions KMNO4 test will run 120 min. If the bath is colder than 15C the test will run longer.
For PTT 50 min at 15 deg C = 30 min at 20 deg C= 20 min at 28 deg C.
Do PTT tests for all tanks at same time—this way you know which tank is the best/ worst.

Notes---
1) Use new latex surgical gloves for each tank. Wash gloves in tank after wearing with Methanol. Use different droppers pipettes for different reagents.
2) No smoking in CCR when the lab test is going on.
3) Write down results immediately
4) Some types of plastics release hydrocarbons. So better use glass bottles.
5) Surveyors methanol should be 0.100 ppm.
6) If PTT test fails you must witness a retest using freshly prepared ships KMNO4 solution.

Strengths:
For 20% HNO3 add 20ml conc HNO3 to 80 ml water.
For 10% AGNO3 dissolve 100 gms of reagent grade AGNO3 in 900 ml water.
For NaCL 10ppm dissolve 10 mg NaCL in 1 litre water.
For KmNO4 0.02% dissolve 0.1 grams crystals in 500 CC water.

We will need to update operator and charterers daily with numbers of WWT. As long as the results get better-- ship cannot go offhire in a court of law.

Reporting to office by email : Code for HC CL and PTT
Tank identity
HC/ scale of nil/ low/ med/ high
CL/ ppm 0.249 to 15 ppm.
PTT/ 50 min at 29 deg C

Compare this with Methanol requirements . You will realise Methanol standard is very low when compared to MEG fibre grade.
Cl/ 2.0
Colour/ 15 Apha.
Suspended matter/ not so stringent
Odour/ allowed
Moisture/ Methanol does not absorb oxygen and moisture.

When you copious spray methanol in a tank first ensure the bulk methanol has less than 1 ppm chlorides and shelf life is <3>
In my experience I have measured 1.5 ppm chlorides in Methanol of 200 litre drums.
Keep Draeger tube for methanol ready. Bring ppm to <80>

Be happy in your work. Only then you can pass the WWT and first foot.

This reagent procedure is so exact that all your readings taken by different people should be the same. After all you are just comparing with a standard solution.



Remember that wall wash test is all about comparing ( holding side by side) the washed unknown solution with a standard known solution---
This is to eliminate
1) contaminated
2) expired
3) unknown strength
--reagents from interfering with your results.

So first you must make standard solutions using pure distilled water and pure lab methanol and memorise its milkiness. Later when you have more experience you need not do this , --- then only it will be a true ‘ on the spot’ roving test.
Have in your boiler suit pocket 2 squirters. One with pure lab methanol and other with distilled lab water. Also have 2 test tubes marked for 20CC.
No filtration is done .
Fast test chlorides:
Take 10 CC methanol wash and 10 CC distilled water. Put one drop of Silver Nitrate (10%). Shake with a stirring gentle motion and compare milkiness with memory in a dark place .

Once in a while test---
Tankcleaning fresh water (fresh water quality )
Amberlite filter discharge ( DI water quality )
Condensate water from steam inlet main pipe ( steam quality)
Bulk methanol from 200 litre drum ( methanol shelf life ). Never use the bottom 2 inches in drum.

Fast test hydrocarbons:
Take 5cc Methanol wash and add 15 CC distilled water, shake vigorously and see the time taken for bubbles to disappear. It should disappear in 30 sec and then look like distilled water. Make sure the tank surface is dry.
This roving test is only for “intermediate on the spot tests” by chief officer , and should not be used as a substitute for final test.
Wash flowing down bulkhead must be collected at the leading dirtiest edge by dragging the funnel down.

Miscellaneous tests:
If the nest cargo is wall wash make sure you use good salt water for washing. Don’t wash with muddy water and spoil your tank when washing near the coast or at mouths of rivers and harbours. In many seas you find cargoes like molasses and palm oils in substantial quantities.
To test sea water for plankton mix 75 ml water with 25 ml Acetone . If plankton is present they will settle down at the bottom.

Acid wash test for BTX: to check for contamination of aromatics by oil. Or to determine if petroleum hc are present in aromatic compounds.
To test cleanliness of tank dip cotton in toluene and wipe one sq metre of bulkhead. Wring out the toluene to test.
7 cc Sulphuric acid + 21 ml Toluene wash shake 100 times and stand for 10 min . Should be clear if no oils or fats are present. Color of acid at the bottom of the tube is compared with standard shades

NaOH fatty acid test:
The quantity of fatty acid in veg or animal oils is a measure of the quality of oil or the degradation which occurred during transport. The sample is first dissolved in alcohol and afterwards neutralised with NaOH. The quantity of NaOH required is a direct indication of the acidity of the oil. You can use ph value paper to detect the change or do a titration with coloured lab reagent phenophtelein—to indicate the change from acid to neutral ( end point of titration ) to alkali.
Even if miniscule amount of previous cargo is seen visually , never conduct WWT or never start to remove hydrocarbons by methanol spray or to improve PTT. Don’t spend costly chemicals and time in vain.
                         
                          Chemical Grade Methanol
Lab methanol must have minimum specs as follows-
Permanganate Fade Time (Min) - 100 minimum
Chloride, as cl (ppm wt) - 0.05 maximum +
Colour (APHA) - 1 maximum
Hydrocarbon test - PASS
Residual odour * - NIL
(*) Residual odour is determined by evaporating 100 ml of methanol on a 10 cm filter paper. The paper, when just dry, is tested for any odour. None should be detected. It is permitted to use a fan blower to assist evaporation.
