液化天然气接收终端小型实验装置流程设计

海上进口液化天然气(LNG)运输船到达后，通过接收终端卸载、储存、汽化后输送给用户。浙江大学制冷与低温研究所与中石油管道研究中心合作，设计了一套额定流量为2m³·h^-1的LNG接收终端小型实验装置，用于模拟终端运行重要功能和操作特性，包括卸载、储存及汽化过程，同时可提供一般LNG流动特性、分层流动、低温阀门检测、天然气泄漏危险的评估。本实验装置考虑LNG冷能利用实验对装置的扩建需求。通过运行该模拟装置，可以掌握LNG接收终端的操作规律，并对控制、安全等方面积累实际经验。本文给出了该实验装置流程设计和AspenPlus数值模拟结果。

Flow chart design of small experimental facility for LNG receiving terminal

The LNG receiving terminal is used to unload, save and boil off the liquefied natural gas transferred by the marine LNG tanker before it is sent to the customer.Cooperated with the PTC, IRC designed a small experimental facility with rated flow rate of 2m³·h^-1 to simulate the operation and manipulation process of a practical LNG receiving terminal.Inside the general unload, save and boil off processes, the facility can provide the experimental base for the LNG flow characteristics, inspection of the cryogenic valve and the risk evaluation in case of the LNG leakage, and the extensive construction in the future is also considered.The aim of the facility is to accumulate the operating and manipulating experience on the aspect of the LNG receiving terminal.The present paper provides the design of the flow chart for the facility and the numerical simulation results are also presented with the software AspenPlus.
