Abstract
Production of propylene is increasing steadily all over the world. For example, it increased by approximately 8 times in the USA and Japan from 1965 to 1980 [I]. Many installations for combined refining of type G-43-I07 and KT-I oil are supplemented by installations for concentration of propylene in our country for the more complete utilization of the resources of propylene contained in refinery gases. To produce propylene which satisfies the requirements of GOST 25043-81 for the concentration of sulfur compounds, it is necessary to know the group composition of these compounds and their distribution by technological streams, which will permit selecting the most economical and rational scheme for preparation of the raw material for the propylene concentration installation.
