Embodiment Construction

[0017] The description below is based on figure 1 . Untreated contaminated water enters the treatment process through inlet pipe 1 and passes through preparation tank A where the temperature is adjusted to make the water suitable for later hydrate requirements in the process and all solid particles are removed. The temperature of the water is adjusted to the function temperature of the process, while the energy generated or added is heat exchanged with other components of the process to optimize energy utilization. Through pipe 2, water enters reactor B.

[0018] The temperature and pressure in reaction tank B will be determined by the hydrate-forming compound used. There are a large number of possible hydrate forming compounds. For example, they can be selected from C 1 ~C 6 Hydrocarbons, CO 2 , halogenated hydrocarbons (wherein halogen is selected from chlorine and fluorine), tetrahydrofuran, ethylene oxide, rare gases selected from helium, neon, argon, xenon, krypton,...

Abstract

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.

Description

technical field [0001] The present invention relates to a method of purifying water containing non-polar compounds dispersed or dissolved in water. Background technique [0002] In the context of the present invention, non-polar compounds refer to molecules that have a prominent hydrophobic character and thus have a low affinity for water, but these molecules can still exist in water with very low solubility or will enter the aqueous phase through previous treatment , said prior treatment either disperses them in molecular form or somehow disperses them or brings them into the aqueous phase as droplets. Typical examples of such compounds are alkanes, waxes, aromatics and higher hydrocarbons. It also includes fatty acids, alcohols, amines and other organic molecules that are not very water soluble when their hydrocarbon chain lengths are very long. Many of these molecules are not acceptable in the natural environment and therefore should not be present in the effluent strea...
