Abstract
A water absorption pouch comprising an open-mesh, hydrocarbon impervious, cloth (e.g., nylon, polypropylene, fiberglass) container confining a water absorbent polymer phase (e.g., mixture of an alkali metal base hydrolyzed starch/acrylonitrile copolymer or alkali metal alkylcarboxamide and a carboxylmethyl or hydroxyethyl cellulose) and sufficient ballast to make the pouch settle to the bottom of a hydrocarbon liquid. Such a water absorption pouch can be tethered and lowered to the bottom of a hydrocarbon containing vessel to absorb a low lying water phase and then removed, dehydrated by squeezing and reused repeatedly.
