Gas purification technology from oxygen

Abstract

The relevance of this research lies in the need of reproducing and expanding the technological scheme based on the gas field, located in the Orenburg Region. The technology for extracting oxygen from natural gas is not only underdeveloped — the market opportunities are perceived as limited, including the limitations of gas purification equipment (thus, the need for import). Therefore, the industry faces a new challenge — to develop expertise and competence in this area, which will further increase the economic part of the project. Objective: to implement the technology of APG (associated petroleum gas) purification from oxygen for its further supply to the main gas pipeline of Gazprom PJSC. The problem of purifying APG from high oxygen content is considered, showing the advantages and disadvantages of existing schemes, which is of high interest for practical application in field conditions. New environmentally friendly and cost-effective technologies for better treatment of the oxygen content of the APG in the field conditions are presented. The chosen technology excludes formation of toxic by-products and does not require construction of an expensive plant.
