Application

 

Application

Widely used in advanced lubricating oil refining, polymer synthesis, insulating materials, pesticides, pigments, cleaning agents, in the natural gas acetylene industry used as acetylene and advanced acetylene absorbent.


Waste Liquid environmental Treatment:


Used, dirty waste of methyl pyrrolidone because its boiling point is relatively high, therefore, direct recovery can not be used, through the solvent recovery system, vacuum decompression heating, decompression to 5KPa (A), heating to 130℃-150℃ can be NMP recovery, residual NMP polymer and impurity discharge system to the power plant incineration treatment, To ensure the recovery of quality and waste treatment, improve recovery safety factor.
