World demand for textiles is on the rise and there is a need for fiber source that does not require arable land. Ioncell-F is a novel method of producing fiber from pulp. It uses ionic liquid [DBNH][OAc] to dissolve cellulose. Ionic liquid is expensive so it has to be recycled to make the process economical. Ionic liquid is thermally unstable, therefore the recycling has to be done with moderate temperatures. One way to separate and recycle ionic liquid from water is thin film evaporation. The purpose of this study was to model the evaporation of water from water/[DBNH][OAc] mixture in an agitated thin film evaporator in flowsheet simulator Aspen Plus. Accurate modeling of the evaporator is needed to design and optimize the recycling pro...
