PROCESS FOR OPTIMIZING REMOVAL OF CONDENSABLE COMPONENTS FROM A FLUID

摘要

A method for removing condensable components from a fluid containing condensable components. The method involves optimizing the temperature of an initial feed stream including the condensable components through heat exchange and cooling to condense liquids there from. The liquids are removed to form a gas stream which is then compressed and after-cooled to form a high pressure stream. A portion of the high pressure stream is expanded to form a cooled low pressure stream which is mixed with the initial feed stream to augment cooling and condensation of condensable components in the initial feed stream. The method is characterized in that, after mixing the cooled low pressure stream with the initial feed stream, the formed mixture is separated into a liquid stream and a gas stream. The liquid stream and the gas stream are contacted with the initial feed stream in a gas-liquid heat exchanger and in a gas-gas heat exchanger, respectively.
