The raw propylene was purified by the old purification system,and it still had several components which hindered the polyolefin reaction,weakened the reaction activity of the catalyst.In this view,National Energy Group Ningxia Coal Group Olefin Second Branch renovated the old purification system,they embedded the combination process of removing green oil and polar oxygen-containing compounds into the old purification system and set up a cascade control system.The flash evaporation results display that the new purification system has an obvious effect on impurity removal.It effectively solves the technical problem that reaction activity of catalyst is weakened by impure materials,and it also saves the cost and enhances economic benefits and social value.
