摘要
海水开架式气化器(Open Rack Vaporizer,ORV)和浸没燃烧式气化器(Submerged Combustion Vaporizer,SCV)是LNG接收站LNG气化的重要设备。ORV运行成本远低于SCV,但在冬季海水入口温度较低时,ORV操作负荷受到限制。对海水入口温度为2~6℃时ORV的运行情况进行测试,提出了ORV达到最大操作负荷的判定标准。通过Origin软件对海水入口温度、海水出口温度、LNG流量运行数据进行拟合,得到了ORV最大允许LNG流量函数式,可以较精确地计算不同海水入口温度下ORV能够处理的最大LNG流量。利用该函数式,结合某LNG接收站2015-2016年冬季外输量,得出了ORV和SCV运行模式优化方案。通过最大程度利用ORV进行气化外输,LNG接收站冬季气化成本可节约1 070×10~4元。
Open Rack Vaporizer（ORV）and Submerged Combustion Vaporizer （SCV） are important LNG gasification equipments at LNG terminals. The operating cost of ORV is much lower than that of SCV, but the operation load of ORV is limited when the inlet temperature of seawater is low in winter. In this paper, the operation situations of ORV at the inlet temperature of seawater between 2 ℃ and 6 ℃ were tested, and the criterion for determining the maximum operating load of ORV was proposed. Then, the inlet and outlet temperatures of seawater and the LNG flow rate were fitted by means of software Origin, and the function for the maximum allowable LNG flow rate of ORV was established. By virtue of this function, the maximum allowable LNG flow rate of ORV at different inlet temperatures of seawater can be calculated accurately. Finally, the operation mode optimization plan of ORV and SCV was prepared by this function, combined with the sendout rates of one LNG terminal in 2015-2016 winter. Eventually, the gasification cost of the LNG terminal in winter was saved by about RMB 10.7 million by making full use of ORV to the maximum extent for gasification. （8 Figures, 4 Tables, 21 References）
