【摘要】 对一步法乙醛生产流程进行了动态模拟 ,对重点设备氧化反应器和成品塔进行了研究。为了处理好动态模型中多个快速反应间的相互联系 ,从总体角度对各反应的最快速率进行了限制。针对精馏塔实时动态模型中活度系数求解困难的问题 ,充分利用Wilson活度系数模型和Unifac活度系数模型各自的优势 ,采用双层法计算活度系数。并成功地将它们应用于实践中 ,效果良好更多还原

【Abstract】 The situation of reactor with many reactions is studied in this paper. A new method is put forward, and is successfully used to resolve the relationship of reactions. On the other hand, a new way to compute the active coefficient, taking advantage of Wilson model and Unifac model, is proposed by using two layer concept. The techniques above are successfully applied.更多还原
