摘要:
Methods of online cleaning of heat exchangers at elevated temperatures are provided. Cleaning of the heat exchanger is achieved through an increasing heat exchanger effluent temperature of a polymer solution together with operating under optimized process conditions provided by a phase diagram constructed for the polymer solution. The separation of polymer from unreacted monomers and solvent in the polymer solution is carried out by raising the temperature of the polymer solution as reactor effluent flowing through the heat exchanger. Then, subsequently and by reducing pressure of the heat exchanger effluent, the polymer solution separates into two liquid phases.
