利用Aspen Plus软件对二甲醚(DME)合成装置的工艺流程建立了模拟模型,对该流程进行了物料与热量衡算,并利用Aspen Energy Analyzer软件对DME合成装置的换热网络进行了分析与优化。结果表明:DME合成装置可以得到质量分数为99.95%的DME产品,且该装置的物料与热量均守衡,验证了该工艺的可行性;优化后的DME合成装置工艺流程可节省热物流或冷物流能量10 572.3 kW。
- Abstract:
-
A simulation model for the process flow of dimethyl ether ( DME ) synthesis unit was established by using Aspen Plus software. The material and heat balance of the process was calculated, and the heat exchange network of DME synthesis unit was analyzed and optimized by Aspen Energy Analyzer software. The results showed that the DME synthesis unit could obtain a DME product with a mass fraction of 99.95%, and the material and heat of the unit were all conserved, which verified the feasibility of the process. The optimized process flow of DME synthesis unit could save 10 572.3 kW of hot or cold logistics energy.
