Polyester：Nowadays, the polyester capacity of the group has reached 1 million tons in the headquarter in Xiaoshao, Hangzhou.
The polymerization projects of both Rongsheng Petrochemical and Rongxiang Chemical Fiber have applied Dupont technology, and polyester plant is designed and constructed by Chemtex. It can be one of the most advanced polyester plants throughout the world, combining several advantages of short reaction circuit, great production capacity, and low consumption of raw material and public undertaking, etc., in which the reaction is done in the process of one-period esterification and two-period polycondensation.
The polyester project of Shengyuan Chemical Fiber has applied China Textile Industrial Design Intuition’s four-kettle polyester technology of direct polyester, continuous polycondensation. With the guarantee of stable and well-balanced quality, the plant can provide flexibility of operation. Consequently its unit energy consumption of raw material, product quality and integrated energy consumption have reached the international advanced level.
