Methanol cracking-pressure swing adsorption hydrogen production technology is a technology that uses methanol and water as raw materials. It is converted into a mixed gas by a catalyst at a certain temperature and pressure, and then converted into a hydrogen-containing mixed gas by a catalyst cracking at a certain temperature and pressure. A technique for purifying hydrogen by pressure adsorption.
This technology uses natural gas for pressurized desulfurization and chemical reaction with steam in a special reformer filled with catalysts to generate reformed gas containing hydrogen, carbon dioxide and carbon monoxide. After part of the heat is recovered from the waste boiler, the reformed gas is converted The medium CO is converted to H₂, the shift gas is cooled and condensed by gas-liquid sharing, and then purified by pressure swing adsorption (PSA) to obtain qualified product hydrogen.
After the hydrogen-containing (H₂) mixed gas enters the adsorption tower of the pressure swing adsorption (PSA) device, the adsorption capacity of the adsorbent in the adsorption bed for each component in the gas mixture varies with pressure, and the raw gas is adsorbed when pressurized The impurity in the adsorbent and the difficult-to-adsorb component (hydrogen) are output as a product from the outlet end of the adsorption bed. During decompression, the adsorbed impurity component is desorbed and desorbed, while the adsorbent is regenerated. At least four adsorbent beds are used for cyclic operation. Realize continuous output of product hydrogen.
Our company adopts the high-performance Prisson membrane imported from the United States, equipped with a self-designed and perfect process, to recover the hydrogen in the synthetic ammonia vented air and ammonia tank vented gas in the traditional process, and then return to the synthetic ammonia production system or further purification For high-purity hydrogen, to achieve the purpose of increasing production and reducing consumption and as a hydrogenation product, the purity of the hydrogen reaches 90% to 99.9%.
Vacuum pressure swing adsorption (VPSA) oxygen production technology is an oxygen production process with low investment, low energy consumption and low operating cost. It has successively passed the high-tech achievement appraisal of the Ministry of Chemical Industry and the Ministry of Metallurgy. It has been widely used in non-ferrous smelting, steel, chemical, paper, fiberglass and other industries.
Under a certain pressure, due to the dynamic effect, the diffusion rate of oxygen and nitrogen on the carbon molecular sieve is quite different. In a short time, the oxygen molecules are adsorbed by the carbon molecular sieve in a large amount, and the nitrogen molecules are enriched in the gas phase to achieve oxygen and nitrogen separation.
Activated carbon fiber is used as the filter material, which has strong adsorption performance and can filter out the residual oil and odor in the compressed air. It is suitable for compressed air purification systems such as food, beverages, and pharmaceuticals. The system needs to be installed in front of the C level, T-level, A-level or other filters.
Imported hydrophobic PTFE filter element is used to produce sterile compressed air through condensation and separation. It is an ideal gas organic solvent sterilization filter. Mainly used in the pharmaceutical industry, fermentation, food and beverage, beer brewing, biological goods and other industries.
It integrates cyclone separation and cohesive type-level purification, directly intercepts the oil and water in the compressed air, and removes ≥98% of the oil, water and dust in the compressed air through cyclone separation, inertial collision, and gravity sedimentation.
It integrates three-stage purification of cyclone separation, pre-filtration, and fine filtration. It directly intercepts the oil and water in the compressed air. Through cyclone separation, gravity sedimentation, the coarse filter element and the fine filter element are filtered to completely remove the oil, water, and water in the compressed air. Dust, the compressed air filtration accuracy after treatment can reach 0.1μm, and the residual oil content is less than 0.01PPm.
The project has been successfully operated in dozens of installations across the country, and the natural gas purification methane project has been successfully put into operation in Shandong, Shanxi, Hunan, Liaohe Oilfield and other companies.
