GENERAL INFORMATION
The Westlake Environmental Emulsion Cracking System (ECS) is highly efficient in removing free, dispersed and emulsified hydrocarbon products from a waste stream. The model ECS is a modified Oil Coalescing Separator that includes a chemical treatment step both upstream and downstream of the separator for removal of emulsified oils. Lowering the pH of the incoming water destabilizes the petroleum hydrocarbon oil water ionic bond, allowing the oil to become free. The free oil is then removed in the oil coalescing chamber of the ECS tank. The system is completely integrated, and skid mounted.
OPERATION
The three-stage treatment system is complete with gravity flow through a single skid. The system includes chemical feed systems, mixers, pH controllers and controls for all mechanical devices. Raw water enters the initial chamber of the ECS where a pH adjustment and/or an emulsion breaking chemistry are added and mixed to break the emulsions. Oil/water separation begins in this chamber. Water leaving the initial chamber continues to the Oil Coalescing Separator portion of the tank where the free oil coalesces and is removed. Clean water continues to the final chamber where the pH is neutralized prior to discharge. Operation is completely automatic and requires only periodic calibration and check to ensure proper operation.
