RXSOL 202

Description

Product Technical bulletin

Description : 

RXSOL 202  is a very powerful heavy duty alkaline cleaning and degreasing agent. RXSOL 202  is based on strong anionic surfactants and alkaline salts.

Application :

RXSOL 202  is used for general cleaning, tank cleaning and boiler cleaning. RXSOL 202 is especially good for cleaning soot and inert gas(IG) stains, as well as vegetable oils, and some mineral oils. RXSOL 202 works well on many ANNEX II cargoes and ANNEX I cargoes as well. 

Usage and Dose :

Tank Cleaning: 

Before cleaning with RXSOL 202 it is recommended to pre wash with hot water. For drying or semi drying oils a prewash with cold water should be carried out immediately after discharge of cargo to retard oxidation and hardening of oil residues. After 1 cycle slowly start to in-crease the water temperature to increase effectiveness of the prewash.

Reciculation Method:

Recirculation is highly effective. In this method a chemical solution is pumped via a closed loop through a mechanical tank washing machine. The chemical solution is normally prepared in the tank to be cleaned or in the slop tank. Heat is achieved by the use of a heat exchanger, steam coils or live steam injection. The advantages of this method are the recovery of the heat and chemicals to clean additional tanks. RXSOL 202 is circulated as a 1 – 3 % solution > 70 °C for a period of 2 – 6 hours. After circulation rinse thoroughly with water.

Depending on the degree of contamination one solution can be used to wash 1 – 3 tanks. For removal of Inert Gas Soot, a 3 – 10 % solution should be used.

Direct Injection Method:

Inject 1 – 3 % of  RXSOL 202 directly into the tank washing system. The recommended cleaning temperature is 80° C. When completed rinse thoroughly with water.

Tank Rinsing:

In many cases an after treatment with Rxsol  Metal Brite is recommended for the removal of white lime deposits originating from sea water, residues out of the cargo or the combination of caustic with high temperatures. Inject 0.5 % Rxsol Metal Brite directly into the tank washing system. Wash for approx. 20 – 30 minutes, at least 1 cycle. The recommended temperature is > 70 °C. Finally wash the tanks thoroughly with cold fresh water.

Boiler Cleaning:

Prior to acid cleaning of steam boilers which are contaminated with oil and grease or when silicates/calcium sulfates are present it is advised to first perform a boil out operation with  RXSOL 202 . Fill the boiler with a 5 – 10 % solution of  RXSOL 202  in water. Depending on the degree of contamination allow this solution to circulate for 12 to 24 hours at a temperature of 80 °C. After this boil out operation, completely drain the hot cleaning liquid and rinse the boiler intensively with cold water.

Cargo Hold Cleaning:

RXSOL 202  is used to clean cargo holds after carrying cargoes such as pet coke, coal, and mineral oil residues. After sweeping and demucking apply  RXSOL 202 in a 10 – 50 % solution depend-ing on the contamination. Let the product soak for 30 minutes making sure not to let the solution dry on the surface. Then spray off with water.
