Abstract
The problems and causes of the original vacuum distillation system were thoroughly analyzed.On the premise of reducing distillation tanks and vacuum pumps,by reasonably designing the equipment configuration process of the system,selecting a new type of heat exchange equipment,and self-made high-efficiency separation equipment,the condensation(cooling)performance,gas-liquid separation performance,and pipeline flux of the system were improved.The rated pumping capacity of the vacuum system was effectively utilized,resulting in several times higher distillation speed and a significant decrease in distillation temperature,thereby improving product yield,quality,and yield.At the same time,the solvent recovery rate was improved,the costs of water,electricity,steam cooling,equipment maintenance,and labor were reduced,and the emissions of three wastes and subsequent treatment costs were significantly reduced,resulting in significant energy-saving and emission reduction effects.
