Propane precooled (C2N) Ethane-Nitrogen two phase-expander refrigeration cycle for energy efficient LNG production process |
| 초록 |
This study proposes the propane precooling cycle with two phase expander implementation in order to improve the energy efficiency of N2 expander liquefaction process for offshore side. Investigation of cooling effect created due to propane precooling and through expansion of high pressure ethane-nitrogen refrigerant by two-phase cryogenic expander. This work was analysed by simulating in the Aspen Hysys v10 and optimized by modified coordinate descent (MCD). The results displayed that energy consumption for liquefied natural gas (LNG) process can be significantly reduced by 52.45% comparing to the conventional N2 single expander.
