Pressure management for slurry polymerization

摘要

Processes and systems for the production for pressure management of a polymerization product flowing from a loop polymerization reactor to a separation vessel in a slurry polymerization system are disclosed herein. For example, a process comprises withdrawing the polymerization product from a loop polymerization reactor, and conveying the withdrawn polymerization product to a separation vessel via a first pressure differential and a second pressure differential. The withdrawn polymerization product may flow through the first pressure differential before flowing through the second pressure differential, and the first pressure differential may be less than the second pressure differential.

1. A process for pressure management of a polymerization product in slurry polymerization, the process comprising:
withdrawing the polymerization product from a loop polymerization reactor; and conveying the withdrawn polymerization product to a separation vessel via a first pressure differential and a second pressure differential, wherein the withdrawn polymerization product flows through the first pressure differential before flowing through the second pressure differential, wherein the first pressure differential is less than the second pressure differential, wherein the first pressure differential is associated with a first line comprising a continuous take-off valve, wherein the polymerization product entering and exiting the continuous take-off valve has 0.0000 wt. % vapor fraction.
