Filtration Solution Saves Refinery $350,000 in Spent Caustic Disposal Fees

CUSTOMER PROBLEM:

During a brown bag presentation at a refinery, a refinery employee mentioned that spent caustic they normally sell became contaminated through an accidental introduction of dirty water.

RAIN FOR RENT RESPONDS:

Rain for Rent suggested filtering the product back to its original state.

Because of the harshness of the chemicals and a pH of 12-13, only Stainless Steel parts with Teflon gaskets could be used. Rain for Rent proposed filtering the product through a BF200 and PF200 into three 21,000 gallon stainless steel frac tanks using a DV-100SS.

The product was filtered successfully and thus saved the refinery approximately $350,000 in disposal fees.
