Abstract:
1. Process of removing volatile compounds from a fluid (F) containing at least one nonvolatile polymer and at least one volatile compound which comprise at least the steps of: a) treating the fluid (F) in at least one concentrator unit comprising at least a heater ( b) reheating the concentrated fluid (H) from step a) in at least one reheating unit ( c) feeding the reheated concentrated fluid (L) from step b) into at least one extruder unit comprising at least an extruder degassing section comprising at least a conveying section ( d) feeding the concentrated fluid (H or L) from step a) or b) into at least one kneader unit comprising at least a degassing section, a vent port with one or more vapor lines, and an outlet section, whereby volatile compounds are removed through the vent ports and vapor lines to obtain a high viscous fluid (N); e) feeding the high viscous fluid (N) from step d) into at least one extruder unit comprising at least an extruder degassing section comprising at least a conveying section, a vent port with one or more vapor lines, a accumulating section and an outlet section, whereby volatile compounds are removed through the vent ports and vapor lines; f) feeding the high viscous fluid (N) from step d) into at least one kneader unit comprising at least a degassing section, a vent port with one or more vapor lines, and an outlet section, whereby volatile compounds are removed through the vent ports and vapor lines; wherein
