The principal behind cleaning of CARGO hold...
The 1st segment to clean and neutralize coal residue :
Coal contain sulphur and many more others materials which is resulting corrosive effect on metal and painted surface. In chemical terms its proper cleaning means not only removal of its deposit to make surface clear and bright, But chemically neutralization effect also required. Coal remover having chemical neutralization and cleaning formula, This product can be mixed with Alkaline safety liquid in open drums / Tanks as follows :::
1st of all take 100 Ltr COAL remover and mix with 80 Ltr water then add 20 Ltr alkaline safety liquid in drum. Spray this solution on entire surface area, And then use high pressure machine to achielve high dense foam to clean vertical surface of hold effectively. On heavily deposited spotted area This solution can apply directly to get emulsification of solid deposited mass easily.
2nd segment to prepare hold up to Grain standard :
After completion 1st step, dilute alkaline safety liquid again with water and sprayed diluted solution on cargo hold. Use high pressure machine water followed by fresh water rinsing will result cargo hold for Grain loading standard.
Note : Rusted and paint scale Area / part cleaning must required before using of any cleaner including 1st segment suggestion. For RUST REMOVING our product code is ( RXSOL-16-1088-025 ) and for Paint removing chemicals our code is RXSOL-18-1013-025
General cleaning tips :
Preparing Cargo Holds for loading Grain depends on the previous cargo.
1. Cargo Holds must be thoroughly cleaned and dry and trace of previous cargo in frames, beams, girders, and other structure.
2. There should not be any loose rust and or paint scale anywhere in the Cargo Holds, Bulkheads, upper and lower hopper spaces, underneath of Hatch Covers and tank top.
3. There should not be traces of live & dead insect & weevils.
4. Bilge covers should be cleaned of any cargo residues and have enough drain holes. Bilge cover needs to be grain tight but not watertight.
5. Bilge well should be cleaned of previous cargo dray and odour free.
6. Bilge suction should be operational at all the times.
Removal of cargo residue:
Air Blow from top using high pressure air to reach all accessible corners. Cargo to be swept, scrapped & collected in a drum. Attention to be given
• Australian ladder and its platforms and stanchions
• Beams and girders under cross decks
• Frames, beams, girders, and other structure
• Large pipes holding brackets behind the pipes
Then Cleaning and sweeping coal cargo from the hold as maximum possible by HELPER / Crew member
Loose Rust & Paint Scale:
A sharp hand scraper shall be used to take off the peeling rust & paint scale
Special attention to following areas:
• Australian ladder and its platforms, hand rails and stanchions
• Australian ladder and its platforms and stanchions
• Beams and girders under cross decks
• Frames, beams, girders, and other structure
• Large pipes holding brackets behind the pipes
• Hatch coamings and under hatch covers
• Booby hatches & cover
Tank top loose rust
Tank top should be free of loose rust and cargo residue
Any rust which can be scraped by hand scrapers should be removed.
The tank top should be rinsed with fresh water
Cleanliness of cargo hold bilges
Hold bilges must be cleaned thoroughly to remove all residue, rust particles and cargo stains etc.
The filter (Rose Box) must be cleaned thoroughly
The bilge well sections shall be washed with continuous running of sea water to remove all odour and later rinsed with fresh water
How Coal remover cleaning property can be enhanced?
Coal Remover is very effective on COAL stains and deposits, But if coal is containing oily residue then mixing of coal Remover with ANY alkaline Detergent must be required. This is due to the oily nature of COAL RESIDUE.

Oily deposits in steam boilers are a result of oil contamination of the feed water. Most often, the source of the oil is some part of the condensate and return system.
Fuel oil and cargo oils may contaminate the condensate via leaks in the oil heaters or tank heating coils. Lubricating oils may be picked up from steam driven machinery.
Oil deposits can be removed from boilers, L.P. steam generators, etc., by circulating a 2-5% solution of Heavy Duty Cleaner (Emulsifier) through the equipment. Heavy Duty Cleaner (Emulsifier) should never be used as an on-line cleaner. All cleaning should be done off-line.
For maximum cleaning efficiency, the cleaning mixture should be heated to 50° - 60°C (122° - 140° F) and maintained at this temperature during the cleaning operation. If adequate heat is not available, effective cleaning can be accomplished at temperatures as low as 25° C (77° F) using additional time. Carbonized oil or coke may require a two-step cleaning process using FOTTM fuel oil treatment followed by Heavy Duty Cleaner.

Total dissolved solids in Alkali cleaner - includes all solids present in a Alkali Cleaner. Determined by evaporating in a 105 oC oven for 24 hours to evaporate the liquid solution.
Procedure:
Weigh an evaporation dish to the nearest 0.1 mg. Accurately measure a known volume (as much as will fit without spilling) of your sample into an evaporation dish and place in the 105 oC oven for 24 Hrs. After all of the Liquid has evaporated, let the dish cool in a desiccator, weigh the dish plus the remaining solids and record.
Calculation of solids by differentiating "A" and "B"
A = weight of dried residue + dish after 24 hrs at 105 oC (mg)
B = weight of dish (mg)
Finally, percentage mass can be calculated accordingly.
Alkleen Liquid plays very important role for cleaning of tanks, specially when cargo containing fats and oil. Alkleen Liquid effectively emulsify oily mass with water to get dissolve into water. Due to its non caustic based formula Alkaleen Liquid uses becomes wide and non corrosive towards metal surface. Alkleen liquid formulated with corrosion inhibitor to increase its suitability towards tank metal surface, Chemical expert claims that long duration of CARGO in a tank ionized the metal surface. Any chemicals contact can directly damage the metal surface, So presence of corrosion inhibitor in Alkleen cleaner results protection towards tank surface.

Multi Clean Tank Wash Detergent Using-Procedure:-
First of all flush the system with cold water to prevent evaporation rates and polymerization then the most economical method is by direct injection followed by recirculation washing, using tank cleaning machines.
Spraying Method:- Spray onto areas where residue remains following rough washing leave for 10-45 minutes (but do not allow to dry), then butterworth at maximum pressure and warm water 60oC for at least 3 hours, checking that there is no foam remaining in the final stages. Inspects tanks(s) and if desired result has been achieved fresh water rinse and dry.
**Make sure to take all safety precautions are followed when handling / spraying as other GENERAL TANK CLEANER **
Injection Method:- Not applicable.
Re- Circulation Method:- Fill tank with fresh water and heat up to warm 50oC . IF a drop line is available on the tank line system, then start to circulate the water and add the required amount of Caustic flakes and MULT CLEAN to make a 2.5% solution. A stronger solution can be made, but be advised that too much Caustic and too high temperature will result in white powder all over the tank. Under normal circumstances, between 2.5% and 4.5% will be sufficient strength. If there is no drop line, then lower butterworth hoses into the tank from the pump stack header without machines attached and circulate through these hoses while you fill the solution material.
**Use a strainer at the pump stack when circulating any solution.** Tank Lining– Stainless / Epoxy / Phenolic.
What is procedure to cleam Lime from ship hold surfaces?
LIME REMOVER HD is concentrated liquid product specifically engineered to attack, penetrate and remove lime deposit from cargo hold. It is a liquid product designed to Clean and eliminate limestone caustic lime deposits and dry lime stains from cargo.

GD DAY.
As per our experience and general practises we observed that cleaning of STEAM coke becomes very easy and more effective by following this cleaning method...
1st Step spray Sodium Hypo on the entire surface area then continuously followed by Aquatuff High Foam ( dilution ratio 1 Ltr Aquatuff High Foam with 20 Ltr Water). Chemically Sodium Hypo Soften coal deposited particle, while Aquatuff resulting excessive foam with super detergency cleaning action which is resulting in the more satisfactory result.
