Document Type and Number:
Japanese Patent JP5844253
Kind Code:
B2
Abstract:
The device has a flash evaporator combined with a vapor-extruder, where input concentration of the polycarbonate in the flash evaporator ranges between 60-95 percentages of weight. A downpipe evaporator is arranged directly over the extruder. An inlet body of the flash evaporator is designed as a distributor plate with a product distributor or as a tube with an opening. A vapor pipelines are attached at the downpipe evaporator. A vapor pipeline (8) is attached to the downpipe evaporator. The extruder comprises multiple degasification zones (11) in a conveying direction. An independent claim is also included for a method for degasification of solvent contained polycarbonate melt.
