Abstract

Petroleum and natural gases besides hydrocarbons may contain acidic gases - carbon dioxide (CO2) and hydrogen sulfide (H2S), and organosulfur compounds - carbonyl sulfide (COS), gray-carbon (CS2), mercaptans (RSH), thiophenes and other components which complicate the transport and use of gases. In the presence of carbon dioxide, hydrogen sulfide and mercaptans natural occurrence of metal corrosion. Hydrogen sulphide, mercaptans, carbonyl sulfide - a highly toxic substance. High concentrations of carbon dioxide in the gases is undesirable and sometimes unacceptable, and also because, in this case reduced calorific value gaseous fuel. If we look at this issue with these products, the sulfur compounds can be classified as undesirable substances. The technological process of processing of natural gas necessary to provide natural gas purification from acidic components. The article explores the process of purification of natural gas solutions of alkanolamines. The problem of increasing the flow of steam in the process of regeneration of the rich absorbent. One problem that arises during purification of natural gas is the increased consumption of thermal energy. It is well known that heat energy is purchased and it allocated substantial funds. The task of solving this problem may be the use of energy-saving technology, leading to a reduction in wasteful heat loss. To achieve this goal in the work the advanced technology amine purification of natural gas from the acid components with varying degrees of regeneration solution. Upgraded scheme allows to obtain the finished product that meets all quality standards.
