EnvTech’s proprietary ETE Cleaning & Gas Freeing Solution utilizes a strong buffer system in combination with appropriate chelants and surfactant in order to: neutralize polythionic acids on contact, dissolve all scales found in nearly any refinery process unit, and emulsify any hydrocarbon residue contained in a system. The mixture also renders pyrophoric substances inactive and has proven excellent for polymer removal. Additionally, Benzene and other regulated air contaminants have been absent from the vapor spaces of vessels opened after these cleanings.
ETE Cleaning & Gas Freeing Solution is effective, non-toxic, non-flammable, non-hazardous, and non-corrosive. It does not make stable emulsions. Any emulsified hydrocarbons can be recovered in the refinery’s API separator and in most locations the solution can be drained directly to the plant sewer with no ill effect on the wastewater treatment plant. Thus, ETE Cleaning & Gas Freeing Solution not only saves valuable time, but also virtually liminates waste disposal costs.
