Use of acid gases in the production of sodium sulphide

This study was conducted to check the possibility of hydrogen sulfide as a material to produce sodium sulphide. It is a harmful substance that is released during production in many industrial production processes. In laboratory and semi-industrial conditions, the possibility of producing hydrogen sulfide using associated acid gases from hydrocarbon production as raw materials has been established. The resulting purified hydrogen sulfide, absorbed by a solution of sodium hydroxide, is a promising raw material in the production of sodium sulfide. The experiments on the production of sodium sulfide from natural gas processing waste, which contains hydrogen sulfide, showed the promise of using the proposed method. A new method and technology for the production of sodium sulfide has been developed, while the cost of the resulting product has been reduced due to the available local cheap raw materials, widely used in the chemical and mining industries and the simplification of the technological scheme and equipment used. Due to the developed method for the production of Na2S, it is possible to utilize a large number of waste gases from hydrocarbon production, as a result of which both environmental problems of the regions are solved, and it is also possible to obtain a product with great economic profitability.
