Characteristics, Advantages & Applications

  • Effectively removes pet coke and mineral deposits from cargo holds and tanks.
  • Can also be efficiently used as a general purpose cleaner to eliminate bad odors in tanks and other closed systems.
  • Acts quickly and thoroughly.
  • Can safely be used on all metals and metal alloys (even if painted/varnished).
  • Non-flammable, non-toxic, non-conductive and non-volatile.
  • Soluble in seawater and fresh water.
  • No known effect on rubber or plastic compounds.
  • May be combined with a specific range of other products.

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 P.C.S. 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.

Application and Use

A. Dosing Procedure

MARICHEM P.C.S. may be used concentrated or diluted with water, depending on the degree of contamination, the surface area to be treated, the desired degree of cleaning and the available downtime. Actually, the user is the best one capable to regulate the quantity and concentration to be used for the situation at hand.

In any case, when the accumulation is not heavy, a 50% solution with water must be used. Otherwise, MARICHEM P.C.S. can be used undiluted especially when deposition is heavy and hard spots persist.

B. Cleaning Procedure

Conventional cleaning methods such as a brush, hard sponge, thick and hard broom and /or a mop can be used on heavy duty and hard stain deposits.

Note that for heavy accumulations the cleaning procedure might be necessary to be repeated until the results are satisfactory. Furthermore, is important to keep in mind that 1 litre of MARICHEM P.C.S. may cover a surface area of 8-10 sq. meters.
