Dutch gas plant uses polymer process to treat aromatic-saturated water. Anon. OGJ, 2 November 1998, 96(44), 87, 88.
Details are given of a gas-processing plant in Harlingen, Netherlands, that has been running a porous-polymer extraction process since 1994 to remove aromatic compounds from water associated with produced natural gas. In the period, the unit has removed dispersed and dissolved aromatic compounds to a concentration of < 1 ppm with energy consumption of only 17% that of a steam stripper. Glycol treatment, and the liquid-liquid process are described.
