A quench settler or QWSD that catches the hydrocarbon liquids and water from the quench tower creates an interface in the QWSD, and possibly an emulsion layer if too much caustic is added. Knowing the interface level is important in order to properly recirculate the quench water from the settler to the tower and not recirculate the hydrocarbons.(plate) Main Enforcement Order - US EPA(steel) SWMU tl Quench Towers and Quench Tower Sumps The Facility operates two quench towers, one located at the north end and the other located at the south end of the coke oven batteries.
