1) High-quality H2 adsorbents, CO special adsorbents and other adsorbents with large adsorption capacity, good selectivity, high strength and long service life with world class advanced level are adopted. 2) While removing specific gas, the pressure of alkane components can be retained. 3) The selectivity is good, and the adsorption capacity for components other than the specific gas to be removed is weak. 4) Strong anti-interference ability, light hydrocarbons, sulfides and other components in syngas have no effect on the performance of the adsorbent. 5) Using PSA and TSA technologies to remove complex organic compositions. Compared with the hydrogenation method, the the energy consumption is lower.
Hydrogen purification & capture
Developed a high separation coefficient, high-precision special hydrogen extraction adsorbent and high-yield pressure swing adsorption process, which can separate and purify hydrogen from industrial by-product hydrogen-containing gas. The hydrogen product meets the requirements of fuel cell hydrogen and high-purity hydrogen. High strength and excellent performance. It not only has a large dynamic adsorption capacity for hydrocarbon impurities and CO2 components, but also is easy to desorb, and has stable performance for long-term use. Compared with EU/US/Japan origin adsorbents, the performance of this adsorbent is similar, but the price is much lower.
Carbon removal (decarburization) & capture
A special adsorbent for carbon capture has been developed, and the low-pressure adsorption force and adsorption capacity have been improved through special treatment of flue gas, and energy-saving optimization has been carried out in the process. Developed and used low-pressure pressure swing adsorption (0.05MPa) carbon capture package technology to replace traditional pressure swing adsorption technology (0.5-06MPa). The two main advantages are lower energy consumption and less investment, and there is no amine adsorption method Corrosion, secondary pollution and other issues.
1) The liquefaction process of our LNG plants adopts the new DMR refrigeration process, which has low energy consumption and effectively reduces the safety risk of the screw. 2) All valves in the cold box are welded, and there is no flange connection in the cold box, which minimizes possible leaks in the cold box. 3) The LNG process is mature and reliable, the process organization is advanced, the operation and maintenance are simple, and only 3 operators are required for one shift. Starts up quickly (startup time is less than 3 hours). It is especially suitable for small skid-mounted natural gas liquefaction equipment. 4) High degree of integration. The skid-mounted design and manufacture of the device reduces the on-site installation workload, shortens the installation time, and saves the floor area.
1) Mean time failures for special program-controlled valves (except seals) is over 20 years. 2) Drying agent lifetime is over 3 years. 3) Special patented desiccant with strong adsorption power and high performance. 4) Small average drying cost per cubic meter.
1) The product quality is more pure and stable than traditional technology. 2) High purity up to 99.999% is available. 3) Fully automated operation is basically realized. 4) Normal temperature operation, low energy consumption. 5) The unique patented process makes small loss of helium venting, and the recovery rate is over 98%.
1) Automatic operation without unmanned management on site. 2) Uninterrupted operation with stable performance throughout the year. 3) Functions of logic control, interlocking, and alarming available by distributed control system. 4) Process display, alarm, remote start and stop etc on the operator/engineers stations. 5) Regeneration gas is smaller and the recovery rate is over 98%;
1) The recovery rate of carbon dioxide is high, above 98%. 2) Uninterrupted running throughout the year. 3) Clean food grade liquid carbon dioxide is available. 4) Hydrogen production together available.
