京津冀地区LNG点供经济性分析——以中国石化天津南港LNG接收站为例

Economic analysis of LNG point-to-point supply in Beijing-Tianjin-Hebei regions——A case study of Sinopec Nangang LNG terminal in Tianjin

基于LNG点供工艺流程及特点,对中国石化天津南港LNG接收站的气源以LNG气化站点供模式供应京津冀地区的经济性进行了分析。LNG气化站储罐规模在100~900立方米,日供气规模1.9万~17.1万立方米。LNG点供终端用气价格由气源价格、槽车运输加价、LNG气化站加价组成,气源价越低、年用气量越大且稳定、运输距离越短,点供终端气价越低。当LNG气源价格为2.15元/立方米时,京、津、冀三地LNG点供终端气价分别为2.43~2.70、2.4~2.51和2.39~2.59元/立方米,明显低于当地的城市燃气一般工业用气价格;当气源价格为2.5元/立方米时,LNG点供北京和河北时仍然较城市燃气便宜,但点供天津时较贵。

This paper analyzes the economy of LNG point-to-point supply from Sinopec Nangang LNG terminal in Tianjinto Beijing-Tianjin-Hebei region on the base of process flow and characteristics of LNG point-to-point supply, with the daily gasconsumption between 19000-171000 cubic meters and the LNG storage tank in the gasification station between 100-900 cubicmeters. The terminal sales price of LNG point supply consists of gas prices, tanker transportation markup and LNG gas stationmarkup, it will be lower with lower gas price in LNG terminal, higher and stable gas consumption and shorter transportationdistance. The sales price of LNG point supply to Beijing, Tianjin and Hebei are 2.43-2.70, 2.4-2.51 and 2.39-2.59 Yuan per cubicmeter respectively when gas price in LNG terminal is 2.15 Yuan per cubic meter, which is much lower than the local city gas. Whenthe price in LNG terminal is 2.5 Yuan per cubic meter, the terminal sales price of LNG is still lower than the city gas in Beijing andHeber, but a little higher than the city gas in Tianjin.
