OPTIMIZATION OF NATURAL GAS PURIFICATION FROM SULFUR IMPURITIES USING MODIFIED CLINOPTILOLITE ADSORBENTS

This paper investigates the enhancement of the adsorption properties of natural clinoptilolite for the purification of natural gas from harmful sulfur-containing components, specifically hydrogen sulfide (H2S) and organic sulfur compounds (mercaptans, COS). The study focuses on the acid modification process (dealumination) to optimize the pore structure and increase the dynamic capacity of the adsorbent. Experimental results demonstrate that modified clinoptilolite exhibits significant efficiency, comparable to synthetic zeolites, while offering substantial economic and environmental advantages. The industrial feasibility of the proposed sorbent was validated through pilot tests.
