分子筛再生过程节能优化方案

Optimization scheme of molecular sieve regeneration process energy saving

针对以往空分装置分子筛再生周期初期设定的情况,本文提出分子筛再生周期应具有针对性,即综合考虑分子筛吸附过程的结果、再生气流量、温度等因素调整分子筛再生周期。同时建立了分子筛再生过程的能量模型,通过计算确定不同分子筛再生时所需的能量,避免不必要的能源浪费。

According to the air separation plant molecular sieve regeneration cycle is set at the beginning of the situation, this paper presented molecular sieve regeneration cycle should be targeted. The consideration of molecular sieve adsorption process results, then angry factor flow, temperature was put into adjusting molecular sieve regeneration cycle. An energy model of molecular sieve regeneration process was set up, through the model we can be sure of the different molecular sieve regeneration energy to avoid unnecessary waste of energy.
