Hydrogen purification technology (PSA pressure swing adsorption / TSA temperature swing adsorption)
Recovering hydrogen from various hydrogen-containing waste gases not only provides the hydrogen needed for industrial production, thus reducing production costs and increasing economic benefits, but also alleviates environmental pollution caused by waste gas emissions or direct combustion of waste gases. On the one hand, many industries such as petrochemicals, coal chemicals, and fine chemicals require large amounts of hydrogen as raw materials; on the other hand, these industries generate large amounts of hydrogen-containing waste gas during production, which used to be burned as fuel or directly flared, resulting in waste of hydrogen resources.

Gas drying, dehydration and purification technology
Industrial production often uses various types of gases. The moisture content in these gases can negatively impact their transportation, chemical reactions, and other processes and results, even affecting the safe operation of production equipment. Therefore, the water content in gases is often strictly controlled as an important indicator in addition to gas purity.

Carbon dioxide removal technologies for hydrocarbon gases (associated gas, coal gas, biogas)
Methane is a combustible gas with high calorific value. According to actual needs, using chemical adsorption method to decarbonize and purify hydrocarbon gases containing methane and other high calorific value gases can produce higher-grade natural gas, which can be directly incorporated into the natural gas supply network or compressed and liquefied to become compressed/liquefied natural gas, thus achieving better economic benefits.

Methanol cracking hydrogen production technology
In areas without convenient hydrogen sources, small-scale hydrogen production (below 100 Nm3/h) in industries such as fine chemicals, pharmaceuticals, electronics, and metallurgy generally uses electrolysis of water. This technology is mature, but due to high energy consumption (approximately 5-6 kWh/Nm3H2), the unit cost of hydrogen is relatively high. Therefore, it is more suitable for scales below 100 Nm3/h.

Natural combustible gas found in underground oil fields or coal seams, mainly composed of CH4. Our company's research and development in pressure swing adsorption separation of CH4/N2 technology and new CH4/N2 adsorbents have a significant role in the purification of low-concentration natural gas, making it an effective way to utilize low-concentration combustible gas rationally.

Light hydrocarbon (natural gas, biogas, etc.) steam reforming hydrogen production technology
Hydrogen production from light hydrocarbons (natural gas, biogas, etc.) is a relatively traditional technology, often used in large-scale hydrogen supply situations and dominating industrial hydrogen production. However, since this hydrogen production process requires high temperatures above 800℃, the equipment such as the converter requires special materials, and energy balance and recovery must be considered. Therefore, the investment is large and the process is relatively long, making it unsuitable for small-scale hydrogen production and generally suitable for hydrogen supply quantities above 1000 Nm³/h. In regions with abundant natural gas, natural gas is the best choice for hydrogen production.
