Solvent extraction treatment of caprolactam waste liquid
Caprolactam is a kind of important organic chemical raw materials, the appearance is white powder or crystals, main use is generated by aggregating polyamide slicing, can be further processed into polyamide fibers, engineering plastics, plastic film.
Most used in the production of caprolactam polycaprolactam, used in the manufacture of gears, bearings, steel tubes and the electrical, medical equipment, insulation materials, also used in coatings, plastic agent and a small amount of land used in the synthesis of lysine.
caprolactam production process is complex, process, process, equipment, material cycle, leading to large consumption of raw materials, can produce a large number of caprolactam waste liquid, the by-products and intermediate, separation is difficult, high content of 'three wastes' emissions and waste liquid of caprolactam, for such waste liquid need to extract caprolactam recovery after first for subsequent processing.
in caprolactam waste liquid treatment, the commonly used method for solvent extraction, the. cwl -
M centrifugal extraction machine, caprolactam waste liquid and extraction agent according to certain proportion in the centrifugal extraction machine, with the aid of the rotation of the drum, through the turbine disc and the impeller to make two phase mixing and dispersing quickly, two phase solution fully mass transfer, mixing and mass transfer process.
Mixture again after the effect of drum centrifugal force through two separate out of the body side by side.
Extraction for biochemical treatment in sewage farm, reverse extraction, extraction phase caprolactam and extraction separation, the extraction solvent recycle.
M series centrifugal extraction machine is a new, rapid, efficient liquid-liquid extraction separation equipment.
Extraction company launched. cwl - zhengzhou days
M series centrifugal extraction machine is developed aiming at the disadvantages of traditional centrifugal extraction machine, under the same processing conditions, the series of centrifugal extraction machine power consumption is only 10% ~ 30% of traditional ring gap model.
Centrifugal extraction machine at the same time, the remaining time is short, split phase quickly, high extraction efficiency, save the investment cost and solvent recycling fee.
