In process units or equipment containing atmospheric resid or heavier hydrocarbon, a refinery cutter stock containing our proprietary surfactant additive is re-circulated and heated to as high a temperature as is safe with the cutter stock used (up to 350° F). This mixture is drained to slop tankage prior to re-circulation of ETI Cleaning & Gas Freeing Solution™. The surfactant additive does not stabilize slop tank emulsions (and can help to break them.) The goal of this additional step is to remove the bulk of the heavy hydrocarbon prior to the water-based cleaning. This method provides nearly total recovery of the hydrocarbon value.
