Abstract:

In recent years，in response to worldwide energy crisis and rising oil price，all countries have been making efforts to seek new sources of energy. So how to utilize oil shale has become important. Shale oil condensation recovery system in oil shale retorting affects directly the quality of products，energy consumption and environmental protection. This article introduces several applications of water washing condensation recovery process and oil washing condensation recovery process. Water washing processes include Fushun retort，Maoming retort，Petrosix process and Lurgi process. Oil washing processes include Galoter process and Tosco II process. Comparison was made between the two types of condensation recovery in terms of equipment and process. Though water washing process has been widely used，the shortcomings of the process are low energy recovery，large amount of recycling water，and high energy consumption. Oil washing process is more advanced，and the heat of high-temperature retort gas can be efficiently recovered. But oil washing process has not been used in China by now，and basic research should be done in the future.
