A review on the production natural gas using energy-efficient and environmentally safe and sound technologies

With the rapid development of green energy and its transition to renewable sources, countries and multinational oil and gas companies are increasingly focusing on forecasting global scenarios of the world economy’s demand for hydrocarbon resources. These predictions serve as a key reference point for determining future development strategies. Gas produced from natural sources plays a key role in the global energy industry and in the international balance of fuels. The main objective of the Gas Processing Plants construction is to provide Kazakhstan consumers with high-quality sales gas and increase the stability of gas delivery at the expense of the country’s own resources. In order to meet the technical requirements for finished products, the processing trains of the plant should be equipped with inlet separators, gas dehydration units, gas sweetening unit and sour (raw) gas injection system. This article presents an overview of new gas treatment technologies used in the processes of sales gas production. The classification and brief characteristics of gas sweetening systems, including absorption, adsorption and membrane methods, are described. The different types of zeolites used in dehydration systems are also presented. Special attention is given to gas injection processes.
