METHOD OF PREPARING ODORANT Russian patent published in 1998 - IPC

Abstract RU 2105597 C1

FIELD: gas treatment. SUBSTANCE: preparation of odorant for natural gas including extraction of mercaptans by aqueous alkali solution, desorption mercaptans caused by boiling mercaptide alkali solution obtained, and condensation of gas- vapor mixture to release odorant, is distinguished by that odorant is submitted to adsorption drying followed by two-step regeneration of silica gel with zeolite-regeneration gas and cooling of adsorbent. EFFECT: provided high quality on storage. 2 cl, 1 tbl
