摘要
以现有的生物质乙醇制乙烯实际操作为依据,采用ASPEN PLUS软件对该工艺进行全流程的模拟和节能改进。改进后的流程在脱水反应阶段不需要添加蒸汽,且全流程能耗较现有流程节能20.2%;若脱水反应段采用反应温度更低的分子筛催化剂,过程节能达28.1%。
Energy saving process of ethylene from fermented alcohol was proposed by using Aspen Plus software according to its practical operation.There is no stream added in the improved dehydration process,and 20.2% heat consumption was reduced compared with the current process.If a molecular sieve catalyst,which has lower temperature of reaction,is used,the heat consumption can be reduced by 28.1%.
