Abstract (en)
[origin: WO2022109519A1] Disclosed is a polyolefin discharge cycle comprising discharging an amount of polyolefin granules from a reactor to a product chamber, wherein the reactor is operated at a pressure of at least 20 psia; transferring the granules from the product chamber to a product blow tank; displacing gas through an equalization line from the product blow tank into the product chamber as granules are transferred from the product chamber to the product blow tank; removing granules from the product blow tank; and repeating the cycle of discharging, transferring, displacing and removing of granules; wherein the granules are transferred at a rate of at least 0.01 ton granules/second; and/or wherein the equalization line is purged with gas before or after at least one cycle; and/or wherein the product chamber comprises a content detector such as a nuclear density detector.
