METHOD OF DRYING AIR AND OIL GASES

摘要

FIELD: oil and gas production. SUBSTANCE: wet air or oil gas is passed through calcined natural adsorbent, in particular, siliceous zeolite-containing mixed-composition mineral containing, wt.-%: opal crystobalite, 40-70; zeolite, 9-25; calcite, 10-25; clay constituent, 4-15; sand-aleurite material, the balance. Adsorbent contains 8.0-16.0 wt.-% of CaO and has pore volume (0.15-0.27) 10 and average pore diameter for benzene 5.0-9.0 nm. EFFECT: enhanced drying efficiency. 1 tbl
