Example Embodiment
[0035] In order to better understand the technical solution of the present invention, the present invention will be further described in detail below for the technical solution of the present invention. This combined technical system embodiment is suitable for resin removal of the polypropylene device for a certain amount of 25,000 tons / annual phase polypropylene devices, and the combined process system embodiments are met. figure 1 , figure 2 .
[0036] In the current mainstream polypropylene process analysis and top air chromatography, the characteristic components of polypropylene powder volatilization and odor are mainly micro-propylene oligomers produced in the process of propylene polymerization, such as isomer. C6, C9 and C12 alkane components. In addition to the hexane raw material, the addition of the portion C6 component, the addition of the propylene raw material and the auxiliary agent does not be brought into components such as isomerization C9 and C12 alkanes, whic...
