12000Nm3/H Coal Hydrogen Production Plant With PLC Automatic Control

12000Nm3/H Coal Hydrogen Production Plant With PLC Automatic Control

Shijiazhuang, Hebei Kadenis 12000Nm³/H Coal Hydrogen Production

Technology Application:

Techairs is a domestic company with the most outstanding performance in intermittent production of hydrogen from coal (with wide source of raw material, such as powdered coal, lump coal, anthracite, lignite, industrial coke oven gas and crude gas etc.), and the technology has reached the world advanced level. The coal to gas PSA is successfully adopted for the hydrogen production as well as the crude gas PSA and the coke oven gas purified PSA.

At present, the main purification methods of crude hydrogen include cryogenic method, membrane separation method, absorption adsorption method, palladium membrane diffusion method, metal hydride method and pressure swing adsorption method. In terms of scale, energy consumption and operation

Pressure swing adsorption (PSA) is one of the separation methods with great comprehensive advantages in difficulty, purity and investment. PSA technology uses solid adsorbent to absorb different gases

Adsorption selectivity and gas adsorption capacity on adsorbent change with pressure. The gas separation method is that the adsorbed gas is desorbed by reducing the partial pressure of adsorbed gas under constant pressure. At present, domestic PSA technology has made a lot of improvements in adsorbent, process, control, valve and many other aspects, and has entered the international advanced ranks.

Features:

1.Full set of equipment with PLC automatic control, easy to operate.

2.The temperature, pressure and flow were monitored in the device to ensure the safe and stable operation of the device;

3.PSA desorption gas enter into the recovery system of combustion, recycling of heat, reducing energy consumption.

4.High thermal efficiency, the normal operation of the steam production for self-sufficiency, no additional steam source;

5. gasification water closed loop recycling, to achieve zero emissions.
