摘要/Abstract

摘要： 为降低空气分离(简称空分)制氧单耗,提高富氧燃烧发电系统效率,根据富氧燃烧的需氧特点,提出了三塔空分制氧流程。采用Hysys软件对三塔空分流程进行了模拟,对塔板数、进料位置、空气压缩机中间抽气压力等关键参数进行了优化,并分析了不同制氧浓度下空分系统的制氧单耗。研究结果表明,制氧单耗随氧产品纯度的升高而增加。氧浓度为97%时,三塔空分流程的制氧单耗为0.3544 kW·h/m3,较双塔流程降低近10%,三塔空分流程的制氧单耗优于传统双塔流程,为进一步降低富氧燃烧空分制氧单耗提供了参考。

Abstract: To reduce the energy consumption of oxygen production by air separation and improve the efficiency of oxyfuel power generation, a new triple-column cycle for oxygen production is proposed based on the oxygen requirements of the oxyfuel combustion. With the help of Hysys software, the cycle is simulated, in which the key parameters, such as the plate number, the feed position and the suction pressure of the air compressor are optimized, and the energy consumption for oxygen production with different oxygen concentrations is also analyzed. It is found that the energy consumption for oxygen production increases with the growth of oxygen concentration. When the oxygen concentration is below 99%, the energy consumption of the proposed cycle is always lower than that of the traditional double- column cycle. Typically, with the oxygen concentration being 97%, the energy consumption of the proposed triple-column cycle is about 0.3544 kWh/m3, 10% lower than that of the double-column one. Therefore, it is concluded that the energy consumption of the triple-column cycle is lower than that of the double-column cycle, and it can be a reference for further reduction of the energy consumption for oxygen production in the oxyfuel power plants.
