    摘要: 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.

    摘要: A method of using a particulate matter formed of a tri-dimensional cross-linked superabsorbent hydrogel for stopping leaks in a cooling system of a vehicle. The hydrogel is added to a filled coolant system and the engine is run for a period of time until the leakage stops.
