    摘要： A gas dehydration method and apparatus are disclosed which utilize lumen-side feed, hydrophilic polymer-inside-coated, thin-film composite hollow fiber membranes, the support fiber of which is highly permeable, such composite membranes being used in a module wherein the permeate flows countercurrent to the flow of the feed, and in which dried raffinate gas is mixed with water-containing permeate at a point opposite the feed end of the module.

    摘要： A process for the removal of at least one non-water vapor component of a vaporous mixture, the basic process comprising directing a vaporous mixture against the feed side of a membrane, directing a condensable vapor sweep stream past the permeate side of the membrane in a manner such that the flow of the condensable vapor sweep is substantially countercurrent to the flow of the vaporous mixture, thereby transporting at least a portion of at least one non-water vapor component of the vaporous mixture from the feed side to the permeate side of the membrane to form a combined permeate side mixture of condensable vapor and at least one non-water vapor transported component.

    摘要： There is described a process for the removal of at least one component of a liquid mixture, the basic process comprising directing a liquid mixture against the feed side of a membrane, directing a condensable vapor sweep stream past the permeate side of the membrane in a manner such that the flow of the condensable vapor sweep is substantially countercurrent to the flow of the liquid mixture, thereby transporting at least a portion of at least one component of the liquid mixture from the feed side to the permeate side of the membrane to form a combined permeate side mixture of condensable vapor and at least one transported component.
