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.

PFN-2500D type pressure swing adsorption nitrogen plant

Under a certain pressure, due to the kinetic effect, the diffusion rate of oxygen and nitrogen on carbon molecular sieve is quite different. In a short time, oxygen molecules are adsorbed by carbon molecular sieve, and nitrogen molecules are enriched in the gas phase to achieve oxygen and nitrogen separation.

Box-type movable nitrogen making station

Flexible and convenient to change the use of the place, with remote supervision and operation, remote start-stop, remote operation function, can meet the temporary use of gas customer rental requirements.

Coke oven gas purification device

Coke oven gas in addition to tar, naphthalene, atmospheric desulfurization, fine desulfurization after the production of fine gas, fine gas through compression, pretreatment, pressure swing adsorption, deoxygenation and drying can get high purity hydrogen.

Alkaline water electrolysis hydrogen production device

The alkaline water electrolysis cell for hydrogen production is composed of plates, electrolytes, electrodes, catalysts, diaphragms and other parts. The electrolyte of the alkaline electrolyzed water is a 30% by mass (wt%) KOH or NaOH solution.
