Concentration method of polymer solution

A method for concentrating a polymer solution, polymer treatment method for removing post belonging volatiles need to be addressed when the surface of the heat exchanger hanging indirectly heated flash line and concentrated coking walls cause clogging problems shut down for maintenance. The viscosity of the concentrated polymer solution is an in-line measurement device is detected by the viscosity, it may be readily detected value to control viscosity of the concentrated solution, a concentration of the solution taken out as a product claim qualifier, as the concentration of circulating fluid return unqualified persons static mixer redistilled , the front flasher system - a static mixer and a heat exchanger and an intermediate connecting line is fresh low concentration of the polymer solution and flashed through a concentrated polymer solution alternately. Continuous operation may not stop surface and wall-coke clogging line 6 to 9 months without the risk.
