连续聚酯降负荷运转参数的调整

The Parameter Adjustment of Continual Polyester for Falling the Load Revolution

由于市场需求减少,在保证产品质量的前提下,对德国吉玛公司设计生产的8万吨/年连续聚酯装置进行降负荷生产。通过工艺参数的调整,浆料总量比降低到1.66,酯化温度降低8℃~10℃,压力降低35kPa^40kPa,停留时间不变或增加,预缩聚Ⅱ的液位降低到20%,熔体产量由360t/d降低至156t/d。

Because of the market demand reduces, in under guarantee product quality premise to German Zimmer corporate design production 80kt/a contirual polyester installrnent carries on falling the load production. Through the craft parameter adjustment, the pulp total quantity compared to reduces to 1.66, esterification temperature drop 8℃-10℃, pressure drop 35kPa - 40kPa, the resident time is invariable or the increase, the pre-condensation Ⅱ fluid position reduces to 20%, melting body output by 360t/d reduces to 156t/d.
