| Popis: | The relevance. In recent years, due to the severe depletion of oil and gas fields, there is an urgent need to create new highly efficient technologies to increase oil and gas production both in oil and gas fields. Most of these fields are at the last stages of development, which are characterized by falling reservoir pressure, high water cut, a large amount of mechanical impurities and moisture in the produced hydrocarbon feedstock. As a result, there is an urgent need to develop new processes and improve technologies for field preparation of natural gas. Purpose: analysis of modern industrial processes of natural gas preparation: absorption and adsorption purification of natural gas from water, low-temperature separation, supersonic gas separation technology; choice of the most cost-effective and reliable process and technology for natural gas deep purification from water impurities in the conditions of industrial operation of gas and oil fields of the Russian Federation based on the analysis of technologies. Results. The analysis of industrial processes and methods of drying natural gas: absorption and adsorption drying, low-temperature separation and technology of supersonic separation of gas from moisture content and mechanical impurities, is carried out. The features of these processes, their properties, technological schemes, solutions, as well as advantages and disadvantages are analyzed. It was established that the use of natural gas absorption drying from water impurities makes it possible to obtain dried gas to a water dew point temperature of up to –20 °C. The introduction of the technology of natural gas adsorption drying from water impurities makes it possible to dry gas to a water dew point temperature in the range from –38 to –99 °C. |
