The New Sorbent and the Method of Sulphide and Mercaptans Removal from the Enterprises of Oil and Gas Complex Atmospheric Air

Article Preview

Abstract:

The materials and methods for removing hydrogen sulphide and mercaptans from the air, aimed to improve the areas of oil and gas complex enterprises in health respect, related to the primary processing of oil, natural gas and gas condensate, are often associated with the processing of raw materials containing a significant amount of sulphur compounds such as hydrogen sulphide, mercaptans and others. The enterprises, considering premises for various purposes, in spite of all the measures taken, produce small, below the exposure limits of the amount of hydrogen sulphide and low molecular weight mercaptans while their operation. Despite the fact, that the amount of hydrogen sulphide and mercaptans, contained in ambient, especially in indoor air, is lower than TVL, the operating personnel is constantly exposed to those components. The basis of the sorbent is flask, highly siliceous material. On the surface of the beads adsorbed diethanolamine the acidic gases form fairly strong ionic associates. In the article the mechanism of associates formation, the sorption mechanism for trapping hydrogen sulphide as well as the characteristics of the absorber circuit diagram for cleaning the air of hydrogen sulphide and mercaptans are shown.
