METHOD OF DRYING AND CLEANING NATURAL GASES

摘要

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. ^ 1 tbl, 6 ex
