I. Overview
In response to environmental protection requirements, the comprehensive and efficient utilization of high-purity CO 2 It is increasingly becoming the focus of widespread attention. Our company employs high-efficiency, low-energy-consumption food-grade liquid CO 2 Production technology, for CO 2 makes reuse possible.
Carbon-dioxide-rich gas streams such as lime kiln gas, flue gas, and fermentation gas typically operate at low pressures; therefore, Davco’s low-pressure swing adsorption ( PSA ) Carbon dioxide recovery technology, which can concentrate and further purify carbon dioxide. \ Liquefaction yields industrial-grade or food-grade carbon dioxide products.
Our company also offers products manufactured using the liquid-phase method ( MDEA/MEA etc.) technologies, engineering, and equipment for concentrating carbon dioxide.

Programmable control valves are critical components for the operation of pressure swing adsorption (PSA) and temperature swing adsorption (TSA) units, serving as the key equipment that ensures normal operation and reliable performance. Dakot’s specialized programmable control valves meet the American Petroleum Institute (API) zero-leakage standard, with a proven service life of over one million cycles without leakage, and feature resistance to frequent gas-flow erosion as well as automatic compensation of sealing materials.
Sichuan DKT Energy Technology Co., Ltd. (A subsidiary of Hydrexia (China)) has established the Sichuan Provincial Enterprise Technology Center, the Chengdu Engineering Technology Research Center for Industrial Waste Gas Purification and Utilization, and the China Petroleum and Petrochemical Engineering Gas Separation and Purification Technology Center, and boasts a professional team with high-level innovative R&D capabilities. After more than ten years of continuous research, DKT has successfully developed 30 new adsorbent materials on its own, which are widely used in the petrochemical, natural gas chemical, coal chemical, fine chemical, steel, metallurgical, environmental protection, and new energy industries, thereby establishing a complete industrial chain spanning R&D, production, design, and application.
High-Efficiency Helium Purification and Crude Helium Recovery Technology
For many years, Dakote has been dedicated to the development and application of helium extraction technologies, providing turnkey systems for helium recovery projects that have operated efficiently, safely, and reliably to this day. Specifically targeting helium-bearing feed streams such as natural gas and boil-off gas (BOG), the company has independently developed a patented ambient-temperature separation process for producing high-purity helium. Compared with conventional cryogenic helium separation technology, this approach offers greater operational convenience and significantly reduced energy consumption.
Hydrogen Production Technology
Hydrogen, as the cleanest green fuel, was officially classified as an energy source by the National Energy Administration on April 10, 2020, heralding an explosive surge in demand for hydrogen energy.
In response to the compositional characteristics of syngas generated during the clean, fractionated utilization of modern coal chemical processes and the associated application requirements, a comprehensive integrated technology for syngas separation and purification has been successfully developed. This technology encompasses pre-treatment via temperature swing adsorption (TSA) for impurity removal, sulfur-tolerant wide-temperature shift conversion, organic sulfur hydrolysis, water scrubbing for ammonia removal, MDEA-based desulfurization and decarbonization, fine desulfurization and dechlorination, catalytic deoxygenation, acid-gas desulfurization and sulfur recovery, PSA-based hydrogen enrichment, PSA-based methane concentration, PSA-based CO concentration, and membrane separation. The technology has been successfully implemented in several large-scale coal chemical projects across China and has received unanimous praise from users.
Pressure Swing Adsorption and Membrane Separation Technologies for Hydrogen Purification
Hydrogen is an important green and clean energy source as well as a key chemical feedstock, and has already been widely applied in numerous fields.
