| Abstract: |
| A dynamic model of LNG tank unloading system has been developed by the process simulation software-HYSYS Dynamic based on a real specified LNG tank. Dynamic responses of the operation pressure of bottom feed line have been studied according to the factors including feed flow rate and feed temperature. The results show that the negative pressure operation condition of the bottom feed line shall be considered to guarantee the safety of the bottom line design, and dynamic simulation could be clearly reflected to the dynamic response of bottom feed line operating pressure, and used to instruct the engineering design. |
