- LIQUID-LIQUID SEPARATOR INTERFACE DETECTION SYSTEM AND POLYMERIZATION PROCESS UTILIZING THE SAME

摘要

Liquid-liquid separator configured to receive the polymer solution as an inlet stream comprising solvent, polymer and unreacted monomer produced in the solvent based polymerization reactor via a feed inlet, where the tank provides a residence time of at least 20 minutes and the stream is polymer rich Configured to allow separation into phase and solvent rich phase); Transmits the primary sonic signal from the top or bottom of the liquid-liquid separator and the primary reflector of the sonic signal (the reflector of the sonic signal is produced by the passage of the sonic signal through the liquid-liquid interface between the solvent rich phase and the polymer rich phase) Detecting an interface between a polymer-rich phase and a solvent-rich phase comprising a first sonic transponder for receiving a signal, wherein the first sonic transponder is arranged to transmit a signal traveling perpendicular to the liquid-liquid interface. A system is provided.
