PROCESS FOR SEPARATING PROPANE FROM GASOLINE

The invention relates to a process for separating propane from gasoline According to the invention, the process consists in that, either a part of the main product of the second column or a part of the gasoline feeding the first column or another third gasoline flux at a pressure of 25 35 bars and a temperature of 35 45 degrees C are introduced directly into the reflux vessel of the first fractionating column so that the methane and ethane as well as a part of propane and butane are separated at the top of the first column and the C 3 + hydrocarbon mixture feeding the second fractionating column is separated at the bottom of the first column, the desired propane being separated at the top of the second column and the C 4 + hydrocarbon mixture at the bottom, a part of said hydrocarbon mixture being recirculated to the reflux vessel of the first column and the remainder being stored as terminal product
