FEATURES OF COMMERCIAL TREATMENT OF NATURAL GAS

The relevance. Today, the Russian Federation is increasing the pace of natural gas production by introducing new gas fields. But in addition to new ones, there are developed fields, most of which are at the last stage of development, that is, in a period of declining production. The gas produced from these fields is characterized by low reservoir pressures, high moisture content and mechanical impurities compared to the initial (design) values. The presence of moisture and mechanical impurities adversely affects its further processing and transportation. As a result, when reaching the required values of the industry standard, problems may arise during gas treatment by absorption or adsorption dehydration of natural gas, as well as problems associated with further gas transportation through pipelines. Therefore, the study and comparison of these two technological processes for natural gas preparation are relevant today, since many industrial gas production enterprises use these two processes of gas preparation. The main aim of the research is theoretical analysis of natural gas preparation by two typical processes: absorption and adsorption; selection of the most efficient and cost-effective processes from the point of view of industrial scale in the conditions of gas fields of oil and gas enterprises of the Russian Federation. Results. The authors carried out the review of two processes for drying natural gas by absorption and adsorption from moisture and mechanical impurities and considered the features of two processes, namely the properties of absorbents, adsorbents, typical schemes, foreign experience, as well as their advantages and disadvantages.
