| 摘 要： | 用ASPEN PLUS 软件对某氯乙烯装置进行了严格的数学模拟，并进行了全过程的节能研究。通过减小VC1#塔的回流比，节省了高压蒸汽；通过提高EDC2#塔压，获得了高品位的热源，分别为EDC1#塔、脱水塔、EDC回收塔及HCl塔的再沸器供热，并为EDC2#塔的进料预热。提出的方案可节省低压蒸汽11 450.75 kg/h，中压蒸汽4738.07 kg/h，高压蒸汽6153.51 kg/h，冷却水11 746 343.9 kg/h，年节省费用为2566.0万元。

| Abstract: | The energy-saving technology in balanced oxychlorination producing vinyl chloride monomer(VCM) was studied.Based on the mathematical simulation with ASPEN PLUS,the heat integration between distillation columns or columns and processes was adopted.By reducing the reflux ratio of VC1# distillation column and increasing the pressure of EDC2# distillation column,a higher temperature heat source was obtained.It could heat the reboilers of EDC1#,dehydration,EDC recovery distillation column.This scheme could save ... |
