Through in⁃depth study on the condensing recovery process of shale oil,Aspen plus software was used to simulate the process and optimize the oil shale condensation recovery system.The results show that the yield of shale oil is 80.6% after the simulation of Aspen Plus software.Two schemes are used to optimize the condensation recovery system.In the first scheme,the absorption tower can be removed and the equipment cost can be saved without the need of the saturated gas as the heat carrier. By changing the position of the fan and comparing the oil yield under the full⁃negative pressure and the semi⁃negative pressure.In the second scheme, the yield of shale oil increases by 1% in the semi⁃negative pressure, and the yield of oil increases by nearly 3 million.
