| titleOfInvention | Caprolactam device is refined in crystallization |
| abstract | The invention discloses a caprolactam crystallization refining device, which consists of a caprolactam crystallization system, a mother liquor evaporation system, a neutralization crystallization system or a caprolactam extraction system, wherein a mother liquor outlet of the caprolactam crystallization system is respectively connected with the mother liquor evaporation system, the neutralization crystallization system or the caprolactam extraction system, and a liquid phase outlet of the mother liquor evaporation system is connected with an inlet of the caprolactam crystallization system. The invention combines the crystallization refined caprolactam with the neutralization crystallization or extraction of the device, avoids the complex evaporation, extraction and back extraction treatment process of the crystallization mother liquor, and has the advantages of investment saving, low energy consumption and obvious economic benefit. |
