TH94417B - Process with hydrocarbon gases - Google Patents

Abstract

Has disclosed the process And a machine for reversing ethane, ethylene, propane, propylene and heavier hydrocarbon components. From hydrocarbon gas stream The currents were cooled and divided into the first and second currents. The first stream has cooled. Again, for all this condensation to be substantially condensed and then expanded. To the pressure of the fragmentation tower And was sent to the separation tower at the feeding position in the middle of the first column. The second stream is amplified to the tower pressure and is then delivered to the second central column feed position. The distillation stream is tightened out of the column. Below the feed point of the second current And was pressed to a higher pressure and then was forced to There is heat exchange with the vapor stream in the upper part of the tower for cooling the distillation stream. And condenses all this flow significantly To form a condensation stream At least part of the condensate current has been forced to lead to the fragmentation tower. As the top feed material of the chamber, the quantity and temperature of the feed material into the tower, the separation sequence has Effectiveness of keeping the temperature in the upper part of the separation chamber at the separating temperature. Return the main part of the desired component. In a different form The distillation stream has been drawn. From the column above the feed point of the second current
