ADSORPTION UNIT FOR PREPARATION OF HYDROCARBON GAS Russian patent published in 2020 - IPC B01D53/00 

FIELD: gas industry.

SUBSTANCE: invention relates to gas industry, namely to equipment and technology of hydrocarbon gas preparation, and can be used in gas, oil and other industries on adsorption plants for preparation of hydrocarbon gases. On adsorption plants at drying and stripping of hydrocarbon gas, extracted HMS from three-phase separators is directed into drainage, and in low-temperature processes on adsorption plants, the recovered HMS is regenerated with extraction of highly toxic methanol used as a hydrate inhibitor, and obtained stable hydrocarbon condensate after separation in three-phase separators from gaseous components C₁…C₄ and HMS is removed from plant and shipped to consumer.

EFFECT: ensuring resource saving of the plant, as well as improving environmental safety and enlarging the range of products by obtaining additional liquid products – high-octane gasoline, propane-butane fraction (PBF), prepared water and producing additional amount of fuel gas.
