Beschreibung
Zusammenfassung:	A system for separating a volatile hydrocarbon from a water stream includes a lead mixer-injector device that receives an untreated water stream including a volatile hydrocarbon, injects compressed air into the untreated water stream and mixes the injected air with the untreated water stream to form a first injected fluid stream. A shear mixing device receives the first injected fluid stream from the mixer-injector device and shear gas bubbles within the received first injected fluid stream so that a frothed stream is formed. A lead degas separator receives and separates the frothed stream from the shear mixing device into a volatile hydrocarbon stream and a partially treated water stream based on difference in density. A compressor directs clean and oil free compressed air to the lead mixer-injector device.
