Dear experts, the method of using distillation to remove HCFC-124 from HFC-134a does not yield satisfactory results; the concentration of HCFC-124 cannot be reduced to below 100 ppm. I hope the experts can provide some guidance.

It is possible to increase the load on the tower; distillation can be used to keep the amount of 124 below 100PPM (usually around 70PPM). This is how our company handles it

Could we add WeChat to learn more about this method in detail?

I’m just an operator at the company; there’s nothing complicated about it – ordinary distillation is sufficient to remove 124. After all, 124 and 134a are considered complex components

The key is to determine what level of load to increase to? Could you be more specific?
