聚丙烯生产中原料丙烯的精制

Polypropylene Raw Material Production of Propylene Refined

文章根据丙烯净化的相关原理,考虑其经济价值和工艺流程的要求建立了原料丙烯的净化顺序为:原料丙烯自界区→活性炭塔粗脱硫→固碱塔粗脱水加粗脱硫→分子筛脱水塔脱水→丙烯脱硫塔深脱硫→CO汽提塔脱CO、CO2、氧等不凝气→丙烯脱水塔神脱水→脱砷塔脱砷。

According to the related principle of the propylene purification, considering its economic value and process requirements of feedstock propylene purification sequence is established as follows： the raw material propylene from the battery limit solid alkali-activated carbon coarse desulfurization tower-crude dehydration tower bold-molecular sieve dehydration tower dehydration-propylene desulfurization desulfurization tower deep desulfurization and CO stripping tower CO, CO2 and oxygen non-condensable gas-propylene dehydration dehydration tower god-removing arsenic removing arsenic.
