借助Aspen软件通过建立数学模型,对20万吨/年高压管式聚乙烯装置过程参数进行优化,结合生产实践,对二次机入口温度、压力,二次机段间温度、压力撤热回水温度,脉冲深度、脉冲时间、脉冲间隔,高分液位等参数进行离线优化,并应用于生产实际,有效地提高了反应转化率,增加了装置产率,为企业带来了可观的经济效益。 With the help of Aspen software, the mathematical model was set up to optimize the process parameters of 200,000 tons / year high pressure polyethylene tube unit. Combining with the production practice, the secondary inlet temperature, pressure, secondary section temperature, Temperature, pulse depth, pulse time, pulse interval, high liquid level and other parameters off-line optimization, and applied to the actual production, effectively improve the conversion rate of the reaction, increased device yield, bring considerable economic benefits to the enterprise .
