Abstract

This paper analyses regeneration methods for sorbents and absorbents used in industrial gas purification from harmful compounds, including H₂S, CO₂, SO_x, NO_x, volatile organic compounds, and moisture. The relevance of the study is determined by the fact that the efficiency of gas purification units depends not only on the initial sorption capacity of a material but also on the preservation of this capacity during repeated sorption-regeneration cycles. Thermal desorption, steam stripping, vacuum regeneration, chemical washing, reactivation, and electro-/microwave heating are compared. The selection criteria include capacity recovery, specific energy demand, resistance to degradation, corrosion risk, environmental safety, and industrial feasibility. Particular attention is paid to amine gas treating data for the Shurtan Gas Chemical Complex. An increase in CO₂ concentration in feed gas from 2.31 to 3.37 mol.% results in residual CO₂ of 75-100 ppm in treated gas, whereas the design limit is not more than 10 ppm. The analysis shows that replacing 30% DEA with 40% MDEA can reduce steam consumption for regeneration from 64.0 to 52.3 t/h, ensure residual H₂S below 5 ppm and CO₂ below 10 ppm, and improve process stability without replacing the main equipment. The practical significance of the work is the proposed decision-making algorithm for selecting sorbent regeneration methods in gas purification systems of the oil, gas, and gas-chemical industries of Uzbekistan.
