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.
