摘要:为回收并资源化利用挥发油气,建立了一种集成冷凝、吸附、催化燃烧和氨水吸收制冷技术的油气回收系统。为分析该系统回收油气时的回收率和能耗,结合油气混合物及其组 分浓度数据,对采用该系统回收油气的方案进行建模和计算。利用Aspen Plus软件模拟3级冷凝过程,改变2级冷凝温度,得到相应的能耗、未被冷凝的油气量和组分浓度；利用Aspen Plus软件模拟单级氨水吸收式制冷过程,得到相应的制冷系数和能耗；估算催化燃烧子系统所需的油气量；对于吸附子系统,只考虑吸附过程,进入吸附装置的油气全部得到回收。通过计算求得油气的回收率和系统的能耗。结果表明:采用该工艺系统回收油气时,回收率和能耗均随二级冷凝温度的升高而降低；相较于传统的“冷凝加吸附法”工艺,该工艺系统的能耗降低30%左右,回收率仅降低2%左右。

Abstract:An oil vapor recovery system integrating technologies of condensation, adsorption, catalytic combustion and absorption refrigeration is built and performance is theoretically analyzed in this paper. Absorption refrigeration is used to undertake partially the cooling demand in condensation and driven by consuming little amount of oil vapor in catalytic combustion. Simulation is conducted with Aspen Plus, concerning recovery rate and energy consumption in recovery of four oil vapor samples with different component and concentration. In condensation module, triple-stage condensation is considered with variation of condensation temperature in the second stage. In absorption refrigeration module, ammonia-water working pair is adopted in single-stage system. In adsorption module, only adsorption process is involved to simulate oil vapor recovery. It is concluded that both oil recovery rate and energy consumption decreases with condensation temperature in the second stage. Comparing with those in regular system integrating condensation with adsorption, energy consumption is reduced by 30% in the system proposed in this paper, with only 2% decrement of oil recovery rate. Therefore, the oil vapor recovery system integrating technologies of condensation, adsorption, catalytic combustion and absorption refrigeration is valid and energy-efficient.
