Cleaning of natural gases from mercaptans
One of aggressive components of natural gas are mercaptans. In view of toxicity and high corrosion activity of these components gas thin cleaning from them is necessary. Applied at the enterprises of gas industry absorbing methods of cleaning from sulphurous compounds, in particular, cleaning process with the use of amine solutions as absorbents, being effective for hydrogen sulfide extraction, don't provide for demanded extent of cleaning from mercaptans, that’s why application of special methods is necessary for mercaptans extraction from gas. In the article available in the world methods of gas cleaning from mercaptans are described. On the example of the Orenburg and Astrakhan gas-chemical complexes technological schemes of existing at the Russian plants operating processes of natural gas cleaning are described and given at the Russian plants, providing for cleaning quality up to the established standard requirements.
