Technology for Producing CNG/LNG from High-Concentration Methane in Coal Mine Gas
Release Date:
2021-12-21
Source:
To maximize the utilization of coal-bed methane resources, and in response to the challenges posed by the high oxygen and nitrogen content in low-concentration methane streams as well as associated safety concerns, Dakote has, after years of intensive R&D, successfully developed a safe and efficient process for the separation and concentration of methane from such streams. Several invention patents have been granted, and the technology has reached an internationally leading level. Currently, this technology has been implemented on an engineering scale at Yangquan Coal Industry, Jincheng Anthracite Mining Group, Shaanxi Yuxiang, and other enterprises, where it has been operating safely and reliably over the long term, delivering significant economic, social, and environmental benefits.

(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.
