This work firstly presents the rigorous modeling of the two plant-wide glycerol carbonate (GC) production processes through the transesterification reaction of glycerol (GLY). One is the Separated Reaction and Distillation (SRD) process, and the other is the Reactive Distillation-based (RD) process. This work covers the thermodynamic and kinetic verification, the rigorous simulation of the two processes, and optimization of the proposed processes based on simulated annealing method. From optimization, it is found that the RD process reduced about 33.1% cost from the SRD process. Also, carbon emission analyses are performed on the two optimized processes, in which the CO₂ emission amount per unit amount of GC formation (CO₂-e, in kg CO₂/kg GC) are calculated. It is reported that the RD process reduces 36.1% of CO₂ emission (CO₂-e=0.207) compared with the SRD process (CO₂-e=0.322).

这项工作首先介绍了通过甘油（GLY）的酯交换反应对两种全厂范围的碳酸甘油酯（GC）生产过程进行的严格建模。一种是分离反应和蒸馏（SRD）过程，另一种是基于反应蒸馏（RD）的过程。这项工作涵盖了热力学和动力学验证，两个过程的严格模拟以及基于模拟退火方法的拟议过程的优化。从优化中发现，RD工艺比SRD工艺降低了约33.1％的成本。同样，对两个优化过程进行碳排放分析，其中每单位GC形成量的CO ₂排放量（CO ₂ -e，以kg CO _{2为单位）}/ kg GC）。据报道，与SRD工艺（CO ₂ -e ＝ 0.322）相比，RD工艺减少了36.1％的CO ₂排放（CO ₂ -e ＝ 0.207 ）。
