Optimization of separation processes in high-pressure reservoir gas separation technology

The oil and gas sector is one of the leading branches of industry in our country. Millions of tons of oil and gas are produced every year in the Russian Federation. Part of the extracted natural resources is put on the international market, the rest is processed domestically providing the population with energy and other useful substances: sulfur, gasoline, oils, bitumen, and so on. Oil and gas processing is a complex process that requires a large amount of human, energy and technical resources. In the modern world, there are different types of oil and gas processing equipment: separators, reactors, furnaces, coagulators, distillation columns, etc. Separators are used for the primary separation of the reservoir gas from impurities, which are based on the separation process. The raw material for the separation plants is high-pressure reservoir gas, as well as gas for stabilization and purging of wells that consists of gaseous and liquid hydrocarbons, reservoir water and organosulfur compounds. These plants are designed to separate high-pressure reservoir gas produced at the production site into gas, gas condensate and associated water. Possible options for upgrading the design of an oil and gas separator for deep oil degassing are being explored. A final stage separator of the NGS-II-6-3000-09G2S type used in oil treatment plants was adopted as a basic model. The disadvantages of the separator design are listed. Design solutions have been developed in order to eliminate the identified shortcomings. The scheme of the modernized design of the oil and gas separator is illustrated. A detailed description of the principle of operation of the proposed design is presented. Calculations have been carried out to improve the efficiency of oil-gas separation.
