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.

Integrated Gas Separation and Purification Technology for Large-Scale Modern Coal Chemical Industries

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.

Technology for Producing CNG/LNG from High-Concentration Methane in Coal Mine Gas

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. The company has been granted several invention patents for this technology, which now stands at an internationally leading level.

Natural Gas Mercury Removal Technology

Both domestic and international natural gas contain trace amounts of mercury, predominantly in its elemental form. Mercury can corrode equipment, pipelines, and instrumentation, poison precious-metal catalysts, and pose health risks to operating personnel; therefore, it must be efficiently removed.
