consult: Comparison of energy consumption between wiped film evaporator and ordinary reactor distillation
Thread Content
I would like to ask all the equipment experts, how do you compare the energy consumption of using a wiped film evaporator and an ordinary reactor to distill the same material under reduced pressure?
I urgently need to know the comparison of steam consumption between a scraper evaporator and an ordinary reactor for the same amount of materials. Anyone with experience in using this kind of material would like to give you some advice!
The scraped plate evaporators I have seen are currently mainly used for concentration, so they cannot represent distillation. Usually the heavy components are the products. However, kettle vacuum distillation can not only concentrate, but also directly distill the product.
It should be similar. As a heater or evaporator, it is related to the latent heat of the material. To distill it, the corresponding heat must be provided. Kettle distillation and scraper distillation are just a matter of efficiency and yield. The temperature of the kettle distillation is higher, while the scraper temperature is slightly lower, the material residence time is shorter, and the yield is higher for heat-sensitive materials. But it all evaporated in the end. So the difference is not too big.
