| titleOfInvention | Concentrating equipment for fluid containing levulinic acid compounds |
| abstract | The invention relates to a concentration device for a fluid containing a levulinic acid compound, which mainly solves the problems of low yield and high energy consumption in the purification process of the levulinic acid compound in the prior art. The invention at least comprises a pre-filtering membrane and an ultrafiltration membrane along the flowing direction of the fluid; the technical scheme that the pre-filtering membrane comprises a filter paper membrane or a ceramic filter membrane, and the material of the ultrafiltration membrane is at least one selected from polyvinylidene fluoride, polyvinyl chloride, polysulfone, polysulfonamide, polycarbonate and polystyrene better solves the problem, and can be used in industrial production for purifying levulinic acid compounds. |
