| Abstract: | The revamping of the desorption tower in absorption-stabilization system of a 0.8 Mt/a DCC-II unit in Jingmen Petrochemical Company was reported. A mid-reboiler was added to the desorption tower to combine the advantages of cold feed and heated feed, the heat of the stabilized gasoline could be reused and the heat load of the bottom reboiler was reduced. The economic benefit of the application of mid-reboiler technology was 2.339 MRMB per year, and the investment could be returned in 4 months. |
