METHOD OF DRYING AND CLEANING NATURAL GASES Russian patent published in 2012 - IPC B01D53/26 B01D53/04 B01J20/08 B01J20/10 

Abstract RU 2447929 C1

FIELD: process engineering.

SUBSTANCE: invention relates to conditioning of natural and associated oil gases, namely, to their drying and cleaning. Proposed method of drying and cleaning of hydrocarbons C6+ comprises bringing them in contact with combined layer of adsorbents consisting of consecutively arranged adsorbent-dehydrator based on aluminium oxide and fine-pored silica gel, and subsequent reactivation of said silica gel and adsorbent-dehydrator by cleaned gas. Here, modified fine-pored silica gel is used containing 0.01-0.5 wt % of carbon compounds. Contact between natural gases with adsorbent-dehydrator and fine-pored silica gel is realised at their ratio of 5-20% of total charge of combined layer of adsorbents.

EFFECT: higher efficiency.
