Abstract
The present invention includes an apparatus and method for use of distillation packing material made from a non-selective meso/microporous membrane that separates light hydrocarbon mixtures.
Claims17
A distillation packing material for separating light hydrocarbon mixtures comprising a non-selective meso/ microporous membrane.
A distillation apparatus for separating light hydrocarbon mixtures, comprising:
- a. a distillation packing material comprising a non-selective meso/ micro porous membrane bundled in a parallel tube configuration,
- b. a distillation column, defining a top and a bottom, packed with said non-selective meso/ micro-porous membrane defining a liquid side and a vapor side within said distillation column,
- c. a reboiler used to heat liquid light hydrocarbon mixtures creating a vapor on said vapor side and providing a thermal driving force within said distillation apparatus, and
- d. a condenser used to condense said vapor creating a liquid on said liquid side.
