Marichem T.T.C.

Characteristics, Advantages & Applications

• Effectively removes and dissolves mineral oils, grease, petrochemicals and carbon residues from tank surfaces, engine rooms, mechanical installations, engine units, parts and components that experience heavy deposition.
• A powerful sludge conditioner.
• Provides a quick and thorough emulsifying action.
• Can safely be used on all metal surfaces and its alloys (even if painted).
• No known effect on rubber and plastic compounds.
• May be used as a general purpose cleaner to remove oil and grease deposits.
• Non-corrosive, non-conductive and of low toxicity.
• Disperses in water to form a milky-white emulsion before the separation of water from oil.
• Can be combined with a specific range of products.
• Reduces emulsion carryover and permits water-oil mixtures to separate into an aqueous phase and an oil phase.
• Cost effective, easy to apply and use.

During 1996, chemical tankers were only permitted to use tank cleaning agents, which had been approved and evaluated by the International Maritime Organisation (IMO). MARICHEM T.T.C. was evaluated through IMO’s Working Group on the Evaluation of Safety and Pollution Hazards of Chemicals (ESPH Working Group) and found to meet the requirements of paragraph 1.8.2 of the P&A Standards.

Physical Properties

MARICHEM T.T.C. is a powerful liquid blend of powerful petroleum solvents, superior emulsifying agents and high grade surfactants.

Application and Use

A. Dosing Procedure

MARICHEM T.T.C. may be applied fully concentrated or diluted with water. The quantity to be used is proportional to the degree of contamination, the available downtime, the surface area to cover and the desired degree of cleaning.

For heavy contamination, MARICHEM T.T.C. may be used undiluted, where as for lighter contamination we suggest a 30-50% solution with water.

For tank cleaning and sludge conditioning various strength solutions between 0.1-0.3% may be used.

B. Cleaning Procedure

The application of MARICHEM T.T.C. may be done by agitation, recirculation and/or soaking immersion.

Rock and Roll method: This method is applicable for tank cleaning at sea. Fill the tank with 0.1-0.3% of MARICHEM T.T.C. and let the solution to act for 2-6 hours. This will enable the solution to soften, penetrate and dissolve the hard bottom deposits, which have formed. Then fill with seawater at 30% of the tank’s capacity and let the solution stand for approximately 1-2 days time. In that period cleaning will be initiated due to wave motion. Then fill with more seawater to 60% of the tank’s capacity and leave the solution to act long enough, so that complete cleaning due to wave motion/natural agitation is accomplished. Afterwards, discharge the tank out and rinse off by filling the tank 1-2 times its capacity with seawater.

Note that MARICHEM T.T.C. must always be fed to the tank and then to the bunkers.

Recirculation Method: Slop water should be pumped ashore or should be pumped to ship’s slop tanks after finishing with the cleaning procedure.

Soaking Immersion method: After the solution is prepared, immerse the part, component or unit to be cleaned, and leave it to soak for 30 minutes. Afterwards, rinse thoroughly with water.
