Natural gas and light hydrocarbon hydrogen production utilizes natural gas and other light hydrocarbons as feedstock, employing Steam Methane Reforming (SMR) and Water-Gas Shift (WGS) as core technologies to generate hydrogen, followed by purification through MDEA (Methyldiethanolamine) decarbonization and PSA (Pressure Swing Adsorption) to obtain high-purity hydrogen. Techairs has delivered over fifty natural gas hydrogen production projects with capacities ranging from 200 to 40,000 Nm³/h, achieving hydrogen purity of 5N–6N (99.999%–99.9999%) for applications in petroleum refining, traditional chemicals, fuel cells and hydrogen mobility, electronics and semiconductors, metallurgy and metal processing, as well as food and pharmaceuticals.

Methanol-to-hydrogen production is a process in which methanol and water, as feedstocks, undergo a reforming reaction over a catalyst to generate hydrogen, which is then purified by technologies such as PSA to obtain high-purity hydrogen. Techairs has completed over 200 methanol-to-hydrogen projects, with capacities ranging from 35 to 40,000 Nm³/h and hydrogen purity reaching 5N to 6N. The produced hydrogen is suitable for fuel cells and hydrogen mobility, traditional chemical industries, laboratories and research facilities, electronics and semiconductors, metallurgy, glass, ceramics, and other sectors.

Biogas-to-hydrogen is a process in which biogas is used as feedstock, first subjected to desulfurization via alkaline method or iron complex method, and then decarbonized by VPSA to produce biomethane. The biomethane then undergoes Steam Methane Reforming (SMR) and Water-Gas Shift (WGS) to generate hydrogen, which is further purified through MDEA decarbonization and PSA to obtain high-purity hydrogen. Techairs is the first in China to have developed and mastered the complete set of patented technologies for biogas-to-hydrogen, which is widely applied in green hydrogen, fuel cells, chemical industry, and other fields.

Organic dehydration refers to the process of removing water from a mixture of organic compounds and water using Pressure Swing Adsorption (PSA). As early as 2004, Techairs designed the largest ethanol dehydration unit at that time, with a capacity of 460,000 tons per year. Currently, the largest unit built has reached a capacity of 600,000 tons per year.

Gas separation is a process that utilizes the characteristic of different gas components having varying adsorption capacities on solid adsorbents as pressure changes. By periodically altering the system pressure, the separation of mixed gases is achieved. Techairs Dual-High Pressure Swing Adsorption technology (THiPSA™) and Full-Temperature Range Pressure Swing Adsorption technology (FTrPSA) provide a solid technical foundation for gas separation, purification, and upgrading projects. These technologies have been widely applied in various industries, including petroleum, fine chemicals, photovoltaic semiconductors, and industrial gases.

The fully automatic load regulation is a dynamic optimization system realized by integrating multivariable control strategies and intelligent algorithms. Its core lies in coordinating automated operations across feedstock handling, reaction control, and product purification. Under the control of this system, automatic load regulation can be achieved simply by inputting the rated load of the unit, and it is applicable to any load within the unit’s turndown range. Project managers can remotely monitor the unit's operation, significantly reducing the burden on on-site personnel, avoiding human errors, and optimizing production.

Skid-mounted modular construction refers to the modular prefabrication and assembly of a unit in a specialized workshop, followed by pre-shipping inspection at the factory, and then transportation to the site either in modular or fully integrated form. It can be divided into two types: modular and integrated. In 2014, Techairs established a dedicated skid-mounted modular manufacturing base, realizing a one-stop production model that significantly improves production efficiency and product quality.

Techairs Remote Service Cloud Platform was created in response to the needs of the times, specifically designed to address the shortcomings in “service” within the company and even the industry. It provides an integrated solution that offers comprehensive services to users. Guided by the corporate spirit—“Creating Value through Technology, Winning the Future with Excellence”—the platform works together with users to pursue a promising future. The main functions of the Remote Service Cloud Platform include routine equipment operation and maintenance, fault alarming and handling, periodic operation reporting, and unit optimization and retrofitting.

Adsorbent is a solid substance capable of adsorbing specific components (adsorbates) from gases or liquids through its surface or pore structure. Techairs has developed a wide variety of molecular sieve adsorbents featuring large specific surface area, high adsorption selectivity, and the ability to be regenerated and reused. Under stable feed gas composition, these adsorbents can achieve a service life as long as that of the unit itself.

A catalyst is generally a substance that increases the rate of a chemical reaction without altering the standard Gibbs free energy change of the reaction. It can also be described as a substance that accelerates the reaction rate without shifting the chemical equilibrium, while its own mass and chemical properties remain unchanged before and after the reaction. Techairs has developed bifunctional, high-performance catalysts featuring poison resistance and anti-coking properties, which have laid a solid technical foundation for the company's hydrogen production technologies.

A program-controlled valve is a pneumatically actuated on-off valve that can be connected to a DCS (Distributed Control System) or PLC, enabling remote control via computer programs. The high-performance specialized program-controlled valves adopted by Techairs feature superior sealing performance, zero leakage operation under high-frequency cycling, fast response speed, and the ability to handle high differential pressure conditions, among other advantages. They are widely used in Pressure Swing Adsorption (PSA) units for a variety of industrial gases, including oil products, natural gas, hydrogen, carbon monoxide, nitrogen, oxygen, reformate gas, FCC dry gas, and more.
