Features and process characteristics of NMP Recovery and Disposal System

Follow me on:

N-Methyl-Pyrrolidone, N-Methyl-2-pyrrolidone,1-Methyl-2-pyrrolidone, Methylpyrrolidone, NMP solvent is a solvent with high solubility and low toxicity.  It is an excellent advanced solvent, widely used in petrochemical, pharmaceutical, electronic materials and other fields, can be used for acetylene extraction, syngas  desulfurization, lubricating oil refining, lubricating oil antifreeze agent, olefin extraction agent, insoluble engineering plastics polymerization solvent, agricultural herbicide, insulation materials, integrated electric production,  PVC tail gas recovery, cleaning agent, dye agent, dye auxiliaries, dispersants, etc.  The solvent refining process has the characteristics of good quality and high yield, and is often used in the refining of smooth oil.

NMP recovery and disposal system features:

Ⅰ. Features of NMP recovery and disposal system:  

1. High recovery efficiency, recovery of more than 90%, recovery purity of more than 85%.  

2. Simple installation: compact box design, accounting for a small space and foundation, lightweight design, greatly reduce the installation cost.  

3. Low power consumption, machine power 3-5KW  

Ⅱ.The process characteristics of the recovery device  

1. One-to-one relatively independent recovery device ensures the recovery efficiency of NMP and smooth operation of coater. According to the successful experience of our company, each coater is equipped with an independent NMP recovery device, which has the simplest operation management, the highest recovery efficiency and the best energy saving effect.  

2. Improve the recovery device, refrigeration system stability and safety.  

3. High degree of automation: each set of recycling device is designed with automatic control system and interlocking system, can ensure the coating machine and recycling device safe consumption, smooth operation.  

4. Common equipment selection, equipment manufacturing, equipment installation method and optimized process flow eliminate the phenomena of running, running, dripping and leakage often presented by ordinary NMP recovery device.  

5. The emission standard can be lower than 300ppm.  

6. The recovery rate of the device is ≥90% in the case of normal coating, pipe length less than 15 meters, and recovery liquid concentration ≥80%

7. The power of each set of the device is about 3-5KW.  

There are many applications in China, and welcome to China to visit.

All the details depend on the exact project. There are best engineer for you to offer the solution. Choose us not only can improve the the recycling rate and also save big cost for the NMP solvent.
