Hi,

I need your help: I would like to know how to improve vacuum distillation process regarding polyester production. The reaction is carried out at 220 degrees Celsius and bottom of the column at 110-120 degrees C and at these conditions much of the DEG and MEG is distilled off when removing the water produced by polycondensation mainly when working under vacuum distillation

If someone here has experience on this kind of process, please, help me with tips/tricks to improve my process decreasing the amount of glycol that is distilled off.

The reactor is charged with Adipic Acid, MEG and DEG.

Sorry any mistakes with my written english: I´m brazillian.

Best regards,

Rodrigo Toledo
