Capacity: 80kgs/h,160kgs/h for industrial grade, 100kgs/h-500kgs/h for electronic grade

Purity: 99.9% industrial grade or 99.9995% electronic grade

Raw material: Solid/liquid ammonia nitrate for industrial grade plant, industrial grade N2O for electronic grade plant

Process description for industrial grade N2O plant : Pour the ammonium nitrate into the melting vessel, add a small amount of water and a catalyst, and use electric heating to melt the ammonium nitrate into a liquid state. The material is injected into the reactor by the injection pump, and the ammonium nitrate decomposes in the reactor, and the temperature, pressure and liquid level in the reactor are guaranteed to be stable through the control system. The decomposition products enter the condenser for cooling, and the condensable water is discharged. The cooled non-condensable gas N2O, etc. is washed by a multi-stage purification tower to remove impurity gases and then enters the buffer gas cabinet. After being pressurized by the compressor, impurities such as moisture are deeply removed through a multi-stage dry adsorber, condensed and liquefied in a high-pressure condenser, and then stored in a low-temperature storage tank.

Process description for electronic grade N2O plant : The industrial-grade liquid nitrous oxide from the general gas storage tank enters the rectification tower after precooling, and the light impurities are discharged from the top of the tower along with the gas phase, and the purified liquid is transported into the high-purity storage tank by a cryogenic liquid pump after heat exchange , the high-purity product is then filled into the steel cylinder through the filling pump.
