二次闪蒸工艺对合成橡胶凝聚工艺节能效果的影响

Effect of Second Flash Evaporation Process on Energy Saving of Synthetic Rubber Solidification Process

采用化工模拟软件Aspen Plus定量分析二次闪蒸工艺对合成橡胶装置凝聚工艺节能降耗的影响。通过模拟计算确定合适的预热温度,并对增加二次闪蒸工艺前后蒸汽消耗量和循环水用量进行对比分析。结果表明,二次闪蒸工艺的节能效果显著,适合在合成橡胶工业推广应用。

The effect of second flash evaporation process on the energy saving of the synthetic rubber solidification process was quantitatively analyzed by chemical simulation software Asepn Plus. The proper preheating temperature was determined by simulation calculation,and the steam consumption and circulating water consumption before and after adding the second flash evaporation process were compared and analyzed. The results showed that,the second flash evaporation process had a remarkable energy saving effect,and it could be widely applied in the synthetic rubber industry.
