  • Patent number: 10676576
    Abstract: The present invention provides a process for preparing a cellulose solution. NMMO with a relatively low concentration and non-activated pulp are continuously mixed online, the mixed premix is dewatered in evaporation dewatering equipment until an NMMO concentration suitable for swelling is achieved, then, sufficient swelling is carried out under this condition, and the uniformly-mixed and sufficiently swelled pre-swelling solution is subjected to depressurized evaporation dewatering and dissolving by thin-film-evaporation equipment thereby obtaining a high-concentration, uniformly-dissolved and excellently-uniformity cellulose solution. The present invention further provides continuous preparation equipment for the process for preparing a cellulose solution.
