  • Publication number: 20160096745
    Abstract: A system for degassing water includes a membrane contactor of degassing water, and a membrane module for enriching nitrogen from a source having <98% nitrogen purity coupled to said degassing membrane module. The enriching membrane module may be physically connected to the degassing membrane contactor. A method for degassing water includes the steps of: enriching a nitrogen gas having a purity of <98% to a purity of >99% via a membrane module, feeding the enriched nitrogen gas to a degassing membrane contactor, and degassing the water with the degassing membrane contactor. The water may be seawater, and/or ground water, and/or river water and/or surface water.

  • Patent number: 6149817
    Abstract: A shell-less fluid contactor and a process for transferring a fluid component between a shell-side fluid and a lumen-side fluid. The shell-side fluid is introduced through a fluid distribution tube and discharged from the tube into contact with a surrounding bundle of microporous hollow fiber membranes. A fluid component is transferred by diffusion, through the walls of the hollow fiber membranes, from the shell-side fluid to the lumen-side fluid. Multiple contactors can be combined into an assembly for multi-stage processing of fluids.
