WASTE-FREE PROCESS FOR FIELD PURIFICATION OF OIL AND GAS FROM HYDROGEN SULFIDE AND MERCAPTANS
The need to clean crude oil from hydrogen sulfide and methyl and ethyl mercaptans is caused by several reasons: the presence of volatile toxic components creates serious environmental problems, causes accelerated corrosion of pipelines and oil storage facilities, and also causes equipment wear. In view of the foregoing, as well as the development of new oil fields with a high content of mercaptan sulfur and the constant simultaneous tightening of environmental requirements for oil products, make the task of cleaning oil from mercaptans relevant.The article includes basic information about the desulfurization of crude oil, gas and gas condensates, the main reactions occurring during the process, as well as various technologies for demercaptanization of oil and gas, their advantages and disadvantages are identified.The purpose of the work is the theoretical substantiation, development and implementation of a new waste-free technology for cleaning oil from hydrogen sulfide and mercaptans in the fields.The main objectives of the study: analysis of known methods and technologies for cleaning oil from hydrogen sulfide based on literature data; development of an effective non-waste technology for cleaning oil from hydrogen sulfide, based on the use of physical methods and combining the process of removing hydrogen sulfide with oil stabilization.Distinctive features of the proposed project: implementation of a waste-free technology for cleaning oil from hydrogen sulfide and light mercaptans, reducing the consumption of reagents, maximum cost savings, the potential for low-boiling gasoline components in commercial oil, reducing the volume of resources attracted from outside in the production and processing of oil, practically complete elimination of the risk of reaction products getting into commercial oil and oil tanks
