城市燃气转换小规模应用LNG技术经济评价

TECHNICAL AND ECONOMIC EVALUATION FOR CIVIL GAS ALTERNATIVE WITH LNG IN SMALL SCALE

国内城市燃气现正由煤气(焦炉气和水煤气)、液化石油气向天然气过渡。新近兴起的LNG更以高储存效率、高发热量、高安全性、低温、低污染、低价格等突出特点令国内城市燃气供应商和用户共同关注。本文结合小规模LNG生产、储存、运输和使用,对其技术经济性作简单评价。

Domestic civil gas utilization shows itself in a trend from coal gas such as oven gas, water gas and LPG to natural gas. LNG rising freshly draws suppliers and consumers' attentions to utilize, for its protruding character- istic of high storage efficiency, high heat value, high safety, cryogenic temperature, low pollution, low price etc. Technical and economic evaluation, combined with LNG production , storage, handling and utilization in small scale, is present in this paper.
