  • Stripping of contaminants from water
    Patent number: 6193893
    Abstract: Process and apparatus to strip volatile contaminants from a liquid supply stream in which the contaminants are dissolved. A gas inducing mixer-injector injects a stripping gas into the stream to form a mixed stream of liquid with its contaminants and bubbles of the stripping gas. The mixed stream is passed through a tangential degasser separator, withdrawing separated gas and water, while maintaining the flow part from the injector to the outlets of the separator at sub-atmospheric pressure.

  • Injection of soluble gas in a liquid stream and removal of residual undissolved gas
    Patent number: 5674312
    Abstract: Apparatus and process for injecting high concentrations of a treatment gas into a liquid stream which is devoid of undissolved gas or a gas phase. The liquid stream is passed through a gas inducing injector to receive treatment gas, and then is passed through a centrifugal liquid/gas separator from which entrained gases and liquid with dissolved treatment gases are separately withdrawn.
