Document Type and Number:
WIPO Patent Application WO/2012/048003
Kind Code:
A3
Abstract:
A system (100) for mixing a gas in a fluid including an inlet section (120) in fluid communication with a fluid source and a gas source, a nozzle (121), and a flow reverser (104). The inlet section has a throughbore in which the fluid and the gas combine to form a treated fluid. The nozzle receives the treated fluid from the inlet section and accelerates the treated fluid. The flow reverser has an open end in fluid communication with the nozzle and a closed end. The nozzle is oriented relative to the flow reverser to direct the treated fluid toward the closed end of the flow reverser. The flow reverser receives the treated fluid from the nozzle and mixes the treated fluid.
