Inauguration Ceremony for the World’s First 100,000-Ton Green, Low-Carbon Methanol Plant
Recently, Henan Shuncheng Group — Anyang Shunli Environmental Protection Technology Co., Ltd. utilizes carbon dioxide to produce green, low-carbon methanol in a co-production process. LNG Project Commissioning , this project is also The world's first Put into production 100,000-Ton Green, Low-Carbon Methanol Plant 。
Sichuan DKT Energy Technology Co., Ltd.( A subsidiary of Hydrexia (China)) is honored to be the EPC contractor for the three main units of this project. (TSA Pre-purification device, MDEA Decarbonization unit, hydrogen recovery unit ) Design and installation for this project Provide Finished Independent Core Technologies , fully leveraging the unit’s technical advantages of energy efficiency, high performance, safety and stability, simple operation, and high availability.
During project implementation Our company consistently adheres to the principles of meticulous planning, close coordination, and scientific management, striving to deliver projects that are precise, satisfactory, and highly efficient.
As China 2030 Peak carbon emissions, 2060 With the steady advancement of policies related to carbon neutrality, Dakote has leveraged its independently developed technologies to vigorously promote green and clean energy projects, achieving significant economic and social benefits.

This device utilizes our company’s independently developed technology.
Characteristics of Temperature Swing Adsorption (TSA) technology:
1) Design the process appropriately by selecting a single-stage or multi-stage adsorption bed based on the composition and concentration of impurities in the coke oven gas, thereby ensuring optimal purification performance.
2) Design the adsorption tower appropriately, with particular emphasis on the tower diameter-to-height ratio, gas distribution, and mechanical water separation, to eliminate adverse phenomena such as channeling, bypass flow, and the entrainment of mechanical water into the adsorbent bed, thereby ensuring high adsorbent utilization efficiency.
3) The third-generation temperature swing adsorbent, developed and optimized by Dakote Energy, effectively removes impurity components (such as tar, naphthalene, and benzene) from the feed gas. This adsorbent features low bulk density, high pore volume, large specific surface area, and enhanced adsorption capacity, while also exhibiting easier and more complete desorption, thereby ensuring long-term, safe, and stable operation of the unit.
Characteristics of MDEA decarbonization technology:
1) The MDEA acid-gas removal process adopts a single-stage absorption with fully lean solvent, tailored to the characteristics of the gas being treated. This process is simple to operate, requires lower capital investment, and has low power consumption.
2) MDEA solution exhibits extremely low solubility for gases such as CO and H2; therefore, the loss rate of valuable gases during MDEA-based acid-gas removal is very low.
3) MDEA solution exhibits both physical and chemical absorption characteristics, with a high CO2 loading capacity.
4) MDEA exhibits excellent stability, with minimal degradation during operation; it is chemically stable, causes virtually no corrosion to equipment and piping, and results in low solvent loss.
5) The addition of active components to the MDEA solution enhances the solvent’s CO2 absorption rate, increases its CO2 loading capacity, improves desulfurization accuracy, reduces the heat required for regeneration, and ensures more complete regeneration.
6) Reasonably design the absorber tower structure and employ high-efficiency packing to significantly enhance mass-transfer capacity.
7) Reasonably design the structural layout of the regeneration tower and reboiler to ensure stable operation during the regeneration process.
Characteristics of hydrogen recovery (membrane separation) technology:
The hydrogen recovery unit employs membrane separation for hydrogen enrichment. The entire membrane separation system is essentially free of moving parts, features a minimal number of control loops and monitoring points, allows for quick and convenient start-up and shutdown, requires very little maintenance, and achieves an exceptionally high availability.
