Problems of uniform distribution of gas flow in gas drying absorbers when preparing gas for transportation

Abstract

The article highlights the important factors of gas treatment. The dew point of commercial gas is one of the main normalized indicators, since the moisture content in commercial gas has a significant impact on the uptime of automatic equipment, on reducing corrosion of gas pipelines, process equipment and compressor stations during gas transportation. Adsorption drying of natural gas is a widely used method in the Russian gas industry. This method is characterized by the high level of environmental safety. Besides, the advantages of the method include the absence of the liquid phase and corrosive fluids in the commercial gas, low specific adsorbent consumption and the high degree of process automation. The article presents an overview of practical methods of adsorption drying of natural gas when preparing it for transportation. The advantages of adsorption drying over other methods are considered; the constructive disadvantages of absorber types are described; the ways of eliminating them are proposed
