First of all flush the system with cold water to prevent evaporation rates and polymerization then the most economical method of using " Stanrose® Hydrocarbon Remover " is by direct injection followed by re-circulation washing, using tank cleaning machines.
Spraying Method : Using " Stanrose® Hydrocarbon Remover " as delivered in drums, 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 60°C for at least 3 hours, checking that there is no foam remaining in the final stages. Inspects tank(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 “Stancare-HCF Cleans”**
Injection Method : not applicable.
Re-circulation Method : Fill tank with fresh water and heat up to warm 50o
C . 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 " Stanrose® Hydrocarbon Remover " 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.**
Note : Tank Lining– Stainless / Epoxy / Phenolic / Zinc-silicate.
