| 摘 要： | 通过调整聚丙烯装置闪蒸过程工艺参数,考察了生产负荷、聚丙烯颗粒平均直径,物料平均停留时间等因素对闪蒸丙烯汽化率的影响规律,工业试验结果表明,汽化率与生产负荷倒数,颗粒平均直径倒数,压差推动力,平均停留时间成线性关系,根据闪蒸过程数据进行数学关联,建立了闪蒸过程模型。

| Abstract: | The influences of production load, average diameter of polypropylene pellets and average residence time on propylene evaporation rate in flash process were studied via the adjustment of the process parameters of the flash drum. The results show that there exists a linear relationship between the evaporation rate and reciprocal of the production load, reciprocal of the average diameter of pellets, the pressure difference (Ps-P) and residence time, respectively. A model for flash process is established through a mathematic correlation based on the data collected in the flash process. |
