ASPEN控制技术在HDPE装置上的应用

Application of ASPEN control technology in HDPE Plant

阐述了ASPEN控制技术在大庆石化公司HDPE装置聚合C线的应用。实施该项技术后,关键的工艺参数变量完全实现了卡边控制;在生产负荷不变的情况下使产量有所增加;产品质量控制更加平稳;闪蒸罐液位实现了稳定控制;可以实现不同牌号间的连续切换。

The application of ASPEN control technology in polymerization train C of the HDPE Plant of Daqing Petrochemical Company is expounded.After implementation of this technology,the bounder control to the key process parametric variables is completely realized;the production is increased without changing the production load;product quality control becomes more stable;stable control to the flash drum level is realized;continuous transfer between different grades is realized.
