TECHNICAL ADVANTAGES
PATENT EQUIPMENT
Advanced Pressurize esterification reactor, pre-polycondensation reactor, final-polycondensation reactor.
EFFCIENT AND ENERGY-SAVING
No wastewater is generated in the polycondensation system, with the EG spraying vacuum system.
All the EG stripped out during the reaction is recycled.
When producing cationic products, a static homogenizer is installed in the oligomer pipeline to solve the problem of SIPE
dispersion, extend the replacement cycle of spinning components, and reduce the consumption of spinning raw
materials.
LESS WASTE WHEN SWITCHING PRODUCTS
The combination of pipeline injection and upflow pre-polycondensation columns reduced waste during product changeover.
STABLE PRODUCT
High efficiency, shorter react time, lower energy consumption; uniform molecular weight distribution of the product.
Solved the problem of SIPE stability and produced stable CDP/ECDP.
GOOD COMPATIBILITY
Online add modifiers to oligomer pipeline make the unit flexible. One uni can produce variety of differentiation PET products, such as glossy, semi-matte, full-matte, cationic dyeable (CDP, ECDP), matte film, flame retardant, low melting point, water-soluble, semi-glossy, high shrinkage, and bottle grade.
ENERGY CYCLE
Energy recovery and utilization by using the esterification steam energy from the polyester plant to run the bromine chiller to produce chilled water.
