Increasing efficiency of use of dryers at the gas-processing enterprises

Abstract

Gas is the most environmentally friendly type of fuel and its role only increases over time. According to experts ’ forecasts by 2050 its role in the world’s energy balance will be 28-30 %. The main technological process used in gas production and transportation is the drying process. Annually, about 20-25 billion cubic meters of associated petroleum gases are processed at gas processing plants. In Russia, the production of liquefied natural gas is becoming more popular. The quality of associated petroleum gas intended for processing is subject to high demands, such as purification of methanol, mercury and gas dehydration. Mostly dehydration is carried out using zeolites. The paper presents the result. On the territory of Russia, a significant proportion of gas fields contain hydrogen sulfide and organosulfuric compounds, without purification from which gas can not be sold to the main gas pipeline system and consumers. The organization of gas production at the Orenburg and then Astrakhan fields required the use of technologies for gas purification from hydrogen sulfide, production of gas sulfur and post-treatment of tail gases of sulfur production, as well as gas purification from organosulfur compounds.
