BZG Type Thin Film Evaporation Drier is widely used in chemical production process for recovering solvents, decreasing costs, gaining better economic results.
    The process characteristic is that the solvents recovery must be done in the sealing condition, the solid materials or residues are not heat sensitive materials, but the heating media's normally use overheating or relatively high pressure vapor or oil. This equipment have been successfully used in recovering acetic acid for PTA, PEA refinery and catalyst solvents recovery process.
