Claim Text:
1. A process for removal of non-polar compounds from water, wherein the non-polar compounds are present in dissolved or dispersed form, the process comprising: leading the water through a preparation tank wherein the temperature is adjusted and wherein solid particles are removed; leading the water via a first pipe into a reactor tank and mixing the water with a gas hydrate forming compound from a second pipe; adding gas hydrate seeds into the reactor tank from a third pipe which is recycled from a fourth pipe, which is an output pipe of the reactor tank; forming gas hydrate particles from the gas hydrate forming compound and a first portion of the water; attaching or associating the non-polar compounds to the gas hydrate particles; separating the gas hydrate particles and the non-polar compounds from a second portion of the water that did not form gas hydrate particles with the gas hydrate forming compound; melting the gas hydrate particles to liberate the gas hydrate forming compound from the non-polar compounds and the first portion of the water; recycling the gas hydrate forming compound through the second pipe into the reactor tank; and discharging the non-polar compounds and the first portion of the water.
