| titleOfInvention | Concentrating method, treating method, concentrating system and treating system for polyisocyanate residues |
| abstract | A concentrating method and a concentrating system for concentrating polyisocyanate residues that can effectively concentrate polyisocyanate residues from crude polyisocyanate comprising polyisocyanate and polyisocyanate residues in a short time and can also suppress increase in viscosity to provide stable transport of the residues and prevent blockage of the transport line, and a treating method and a treating system for decomposing the concentrated components to polyamine . The polyisocyanate residues are first heated on the boil by the distiller to be concentrated to a midterm concentrating rate, and then, the polyisocyanate residues are concentrated to the final concentrating rate by evaporation using a evaporator. This can allow the polyisocyanate residues to be decomposed to polyamine to be recovered by setting a Cl content of a high boiling point distillate fraction concentrated to be not more than 2 weight% and then putting the high boiling point distillate fraction into contact with high temperature and high pressure water to be hydrolyzed by the decomposing apparatus . |
