摘要

为探索低温空气分离系统(ASU)进行电力需求错峰运行的可行性

将传统空气分离技术与液态空气储能技术(LAES)结合

在谷电期先将富余空气压缩、液化、储存

在峰电期将液态空气作为精馏原料补充到精馏塔

以提高谷时压缩用电负荷、降低峰时压缩用电负荷。与传统空气分离系统相比

氧气产品的标准状态体积流量为10 165 m

/h的低温空气分离储能系统(ASU-LAES)可将压缩能耗的20%由电网高峰时段转移到低谷时段

年度用电成本可减少1.3%～6.8%。ASU-LAES系统的制氧单位压缩能耗为0.349 kW·h/m

设备投资成本为4 034.8万元

动态回收期为4.6～5.2 a。ASU-LAES方案可缓解电网高峰负荷用电压力

充分利用峰谷分时电价政策优势

可创造良好的经济效益。

Abstract

In this study

a combination of air separation unit and liquid air energy storage technology is employed to realize large-scale power demand management of a cryogenic air separation system. The surplus air is compressed

liquefied and stored during valley electricity periods

while the stored liquid air is directly recycled to the distillation column as raw material during peak electricity periods

thus increasing valley electricity consumption and decreasing peak electricity consumption. An air separation unit with liquid air energy storage(ASU-LAES)system producing oxygen with a standard state volume flow rate of 10 165 m

/h shifts the annual compression electricity consumption by 20% from peak periods to valley periods

resulting in a saving of 1.3%—6.8% per year on the electricity costs as compared to a conventional air separation system. The daily compression electricity consumption for oxygen production is 0.349 kW·h/m

. The equipment investment is RMB 4 034.8×10

. The dynamic payback period is 4.6—5.2 a. The ASU-LAES system helps to reduce the peak power supply pressure of the power grid

takes advantage of the peak-valley electricity price policy

and brings economic benefits to the system.
