Modular solvent recovery device |
摘要 |
A process is disclosed for manufacturing a concentrated residue from a photopolymer fluid which includes photopolymer and photopolymer solvent. The photopolymer fluid may be derived by chemically etching a photopolymer layer of a printing plate with a solvent. The process includes distilling the photopolymer fluid to recover the solvent and concentrate the photopolymer fluid to form a concentrated photopolymer residue, and mixing a flash-point-increasing agent with the concentrated photopolymer residue in an amount sufficient to raise the flash point temperature of the concentrated photopolymer residue to a pre-selected temperature to form the concentrated residue. The flash-point-increasing agent may be mixed with the waste photopolymer fluid prior, during, or after distillation. Also, the flash-point-increasing agent includes oils, such as paraffinic and naphthenic oils and a blend thereof.
