Abstract
The article considers the possibility of using natural, environmentally friendly, cheap raw materials as the basis of a complex inhibitor of hydration and corrosion. It is proposed to use bischofite solutions with mass fraction of 24% MgCl2 as a carrier of a complex inhibitor. A set of laboratory studies was carried out in order to eliminate the main shortcomings of bischofite solution. Such disadvantages are that highly concentrated solutions of bischofite, untreated from sulfate ions and iron compounds, without a corrosion inhibitor cause corrosion of equipment and salt deposits. According to the results of laboratory studies, the composition of a complex inhibitor of hydroformation and corrosion based on bischofite was proposed. Based on the results of laboratory studies, suitable reagents were selected for preparing a bischofite solution for use in the processes of production and preparation of gas for transport, and the mechanisms of reagents action were proposed. The results of industrial tests show the effectiveness of a new complex inhibitor. The achieved properties of the complex inhibitor have led to the improvement of technical, economic and environmental performance of gas production enterprises of Ukraine.
