Batch Polycondensation(Semi-continuous)

OBHE can provide various sizes of batch, semi-continuous polyester plant according to the demands from different clients.

“OBHE” Batch Poly Technical Features:

  Since 1996,and has been in production for decades. Slurry preparation system can complete the preparation of modified polyester raw material, catalysts and additives can be added at low temperature

  Addition of second esterification reactor (pre-condensation) facilitate production of differential products, meanwhile it is easy to change product without cleaning reactor, and also avoid start-stop loss and generated waste materials, it can carry on pre-condensation reaction in the second esterification reactor to improve production.

  Vacuum system adopts EG vapor jet pump, EG is completely recycled, saving energy and reducing the amount of generated wastewater.

  It is suitable for developing and producing small-lot differential polyester products.
