Employees of Orenburgneft, Rosneft's key production asset in the Volga region, have patented a technology for reducing the content of hydrogen sulfide and mercaptans in associated petroleum gas (APG). The innovation has been implemented at the Vakhitovsky group of fields of the enterprise, which has increased the volume of rational use of APG from 20 to 80 thousand m3 per day. The economic effect from the implementation of the innovation will amount to more than 1 billion rubles within five years.
The essence of the innovation is to purify the gas flow in the pipeline by feeding a liquid reagent-neutralizer, which removes sulfur compounds from the APG without using additional equipment. Then the primarily purified product is sent to the Zagorskaya complex gas treatment plant for subsequent processing.
The company's specialists were the first to propose the idea of cleaning gas directly in the pipeline, which itself acts as a reactor, and proved its effectiveness. The technology does not require capital expenditures, construction of new facilities or additional equipment.
The introduction of the innovation made it possible to process additional volumes of sulfur-containing associated petroleum gas, increase the production of a wide fraction of light hydrocarbons and dry stripped gas, and supply additional volumes of treated gas to main gas pipelines.
