(renewable)

The large surface area and polar adsorption of 5A zeolite can be used for the deep adsorption of water and residual ammonia. The decomposed nitrogen and hydrogen mixture enters the dryer to remove residual moisture and other impurities. The purification device adopts a double adsorption tower process, one adsorption drying ammonia gas, the other one in the heating state (usually 300-350 DEG C) to suck out the water and residual ammonia, so as to achieve the purpose of regeneration.

13XAPG zeolite:

The utility model is mainly used for purifying raw material gas in large and medium-sized air separation units.

Air purification, removal of CO2 and H2O in air installations;

Natural gas, liquefied petroleum gas, liquid hydrocarbon drying and desulfurization;

Common gas drying.

Special molecular sieve series for insulating glass:

At the same time adsorption hollow glass of water and organic residues, the hollow glass even at very low temperature keeps clear and transparent, fully reduce hollow glass because of changes in seasonal and diurnal temperature difference under strong pressure difference between the inside and outside, completely solve the ordinary insulating glass desiccant to ordinary insulating glass expansion or contraction leads to distortion broken problem, extend the service life of the hollow glass.
