TH24410A - A process and equipment for the removal of non-polymerized gaseous monomers from olefin polymers. - Google Patents

Abstract

A device for the removal of monomers from solid olefin polymers contained in the monomer, consisting of a tapered disposal container, here the container is 0.5 to 1 to 10 in height per diameter. Per 1 and with a wall tapered to an axial angle from 0.5 to 15 degrees; Solids discharge unit located in the lower part of the disposal container; Solid receptor hopper; Entrance of the solid that is in the receiving hopper; Way of entering the address in the receiving hoppers that connect to the entrance. For feeding solids into the disposal container; The entrapment path through which the gas is impermeable, the solid is not under the path Enter which sets the upper limit of the solids extended bed and determines the gas collection chamber between The tops of the disposal container and the detention routes; The path of the gas inlet inside or under the disposal vessel. Expanded bed of solids; And gas exhaust paths connected to the gas collection chamber for The gas is discharged from the chamber, and the process of removing the non-polymerized monomer from solid olefin polymer pellets. And gaseous monomers using the device

Claims (7)

1.Equipment for removing non-polymerized monomers from olefin poly Solids containing monomers Which consists of: disposal container with a tapered wall In which the container is proportional Height to diameter at bases 0.5 to 1 to 10 to 1 and walls tapered to an angle of 0.5 to 15 degrees relative to the vertical axis; Solids discharge unit located in the lower part of the disposal container; Solid receptor hoppers; Entrance of the solid that is in the receiving hoppers; How to enter the address in the hoppers Receiver connected to the inlet for feeding solids into the disposal container; The entrapment path through which the gas is solid Impermeable beneath the feed path that sets the upper limit of the expanded bed of solids and Establish the gas collection chamber between the top of the disposal vessel and the containment path; The path of the gas inlet Disposal container inside or under the expanded bed of solids; Gas vent paths in contact with the room Collect gases to drain the gas from the room. 1. 3.
