METHOD FOR TREATMENT OF WATER COMPRISING NON-POLAR COMPOUNDS

摘要

The present invention concerns a process for removal of non-polar compounds from water, wherein the non-polar compounds exist in dissolved or dispersed form, wherein the water is first led through a preparation tank (A, F) wherein the temperature is adjusted and wherein possible solid particles are removed. The water is then led via pipe (2, 13) into a reactor tank (B, G) and is mixed with a hydrate forming compound from pipe (6, 17), wherein simultaneously hydrate seeds are added from pipe (7, 23) which is recycled from pipe (3, 14) for continuous use in the process; whereby the drops or molecules of the non-polar compounds are attached or associated to hydrate particles being formed in the reactor tank (B, G). The hydrate particles are separated from the water and melted. The hydrate forming compound is recycled through pipe (6, 17) to the reactor tank (B, G) and the non-polar compounds discharged via pipe (8, 22). In addition the invention comprises a device for use of the process as well as hydrates for removal of non-polar compounds in water.
