- Abstract
DHX( Direct Heat Exchange ) process has been used for condensate recovery in Changqing Oilfield since 2018, and the C3+ yield of each train of process facilities has basically reached 95%. But there are still some problems in the operation, such as C3+ yield of certain facilities cannot meet the target and the power consumption of operating the mixed refrigerant refrigeration system is excessive. To resolve these problems, this paper analyzed and optimized the original DHX process by using Aspen HYSYS V12. 0 software. The optimized DHX process ensures that the C3+ yield of various types of condensate recovery facilities is higher than the established target of 95%, and can effectively reduce the energy consumption of the refrigeration system by about 20% ~ 35%. The research results can provide a design basis for the production capacity and efficiency improvement of the existing associated gas condensate recovery facilities and the design of the new associated gas condensate recovery facilities.
