QuenchFlow™: An Integrated Quench Water Treatment System For Ethane Cracker Plants

QuenchFlow™ incorporates proven Veolia technologies, including Veolia’s Autoflot™ induced gas flotation (IGF) and Power Clean® nutshell filters (NSF), in a fully integrated modular system. The contaminated quench water is chemically treated upstream of the Autoflot using an inline dosing system provided by Veolia. It then enters the Autoflot where gas is induced at the bottom of the unit via eductors. The gas bubbles float free oil and suspended solids to the gas/liquid section of the unit, where it forms a froth that is skimmed and removed.
