摘要

根据LNG接气站冷量能级的特点，分析了LNG冷能用于冷库的实现形式，比较了LNG接气站冷能冷库的不同系统流程及特点。在某LNG接气站供气规模为每年4×107 m3，LNG冷量回收率为33%等假设条件下，分析了第三种工艺流程的技术经济性。结果表明：该方案下的接气站冷能冷库系统的年冷量收益为611.3万元，系统运行费用较低，投资回收期小于1年，具有明显的经济效益。

Abstract

According to the energy-level features of cold energy from gasification station

not only the mode of utilizing such cold energy at refrigerated warehouse was analyzed

but also the various system process flow and corresponding features of such cold stores was compared in this paper.Under certain assumed conditions

the technological and economic analysis of the third flow mode was made by taking a gasification station with the gas supplying capability of 4×107 m3 per year as an example.Results indicate that under a 33% cold energy reclaim ratio of the refrigerated warehouse

the annual profit from available reclaimed cold energy of the gasification station is 6.113 million CNY

and the operation cost of the refrigerated warehouse under this mode is low.Therefore its payback period is no more than a year and economic benefits significant.
