Key words:

Classification:

  • Product Description
  • Hydrogen Production Technology from Natural Gas Conversion


    The technology is to use natural gas pressure desulfurization and water vapor in a special reformer filled with catalyst to produce converted gas containing hydrogen, carbon dioxide and carbon monoxide. After recovering part of the heat from the waste pot, CO in the converted gas is converted into CO2 through conversion, and the converted gas is purified by pressure swing adsorption (PSA) to obtain qualified product hydrogen.

     


    Technical features:
    Mature production technology, safe and reliable operation
    The operation control is safe and practical, and the degree of automation is high.
    Low operating costs and short payback periods.
    PSA analytical gas can be burned back, which not only reduces fuel consumption, but also reduces exhaust emissions.

Methanol cracking hydrogen production unit

Methanol cracking-pressure swing adsorption hydrogen production technology is a kind of methanol, water as raw materials, at a certain temperature and pressure by the catalyst into a mixed gas into a certain temperature and pressure by the catalyst cracking into a hydrogen-containing mixed gas, and then through the pressure swing adsorption purification of hydrogen technology.

Natural gas hydrogen production unit

The technology uses natural gas to undergo a chemical reaction with water vapor in a special reformer filled with a catalyst after pressurized desulfurization to generate a converted gas containing hydrogen, carbon dioxide and carbon monoxide. After part of the heat is recovered by the waste pot, CO in the converted gas is converted into H?, and the converted gas is purified by pressure swing adsorption (PSA) after cooling and condensing gas-liquid sharing.

Pressure swing adsorption hydrogen extraction device

After the mixed gas containing hydrogen (H₂) enters the adsorption tower of pressure swing adsorption (PSA) device, because the adsorption capacity of the adsorbent in the adsorption bed for each component in the gas mixture varies with the pressure change, the impurities in the feed gas are adsorbed during pressurization, and the components (hydrogen) that are not easily adsorbed are output as products from the outlet end of the adsorption bed. During decompression, the adsorbed impurities are desorbed and the adsorbent is regenerated at the same time, at least four adsorbent bed cycles are used to operate to achieve a continuous output of product hydrogen.

VPSA pressure swing adsorption oxygen plant

Multi-tower combined VPSA pressure swing adsorption oxygen production technology is a new process with low energy consumption, low noise and low maintenance cost. It has been accepted by the first set of devices in Zhejiang Province and is widely used in non-ferrous smelting, glass smelting, iron and steel smelting, chemical industry, paper making and other industries.
