热耦精馏塔在化工节能改造中的可行性

Study on the Feasibitity of Employing Thermally Coupled Distillation Tower to Save Energy

采用非常规的精馏塔序──热耦精馏塔代替常规塔序，利用严格的精馏过程计算模型，对某橡胶厂溶剂回收系统进行模拟计算，分析热耦精馏塔用于非理想体系精馏中节能改造的可行性。

The solvent recovery system in a rubber plant is simulated by rigorous calculation model of distillation,using irregular column sequence─thermally coupled distillation tower to replace theregular column sequence,The paper analyzes the feasibility of applying thermally coupled distillation to the distillation of nonideal systems with a view to saving energy.
