Drying and Purification of Natural Gas on Modified Clinoptilolite 

Type Zeolite by Adsorption Method

Abstract

Adsorption properties of sulfurous compounds in natural gases have been studied using clinoptilolite type zeolite catalyst with rich deposits in Azerbaijan. As a result, it was determined that the use of modified clinoptilolite is the most effective based on experimental evidence for the adsorption of H₂S, COS and RSH on modified clinoptilolite and NaX zeolite. Based on H₂S and COS adsorption heats in modified clinoptilolite, the optimal temperature of regeneration was determined at 250 °C. This is the value of the rate of desorption of sulfur compounds (H₂S and COS) from NaX zeolite at 320 °C, determined in industry, in other equal conditions. Thermally modified clinoptilolite is shown to have the best absorption and protective properties.
