On January 11th, Wison Engineering EPCCT successfully completed a 72-hour continuous operation assessment of the first ten-thousand-ton-level power plant flue gas carbon dioxide capture and hydrogenation to methanol pilot plant. This achievement not only signifies a major success in the pilot phase of this innovative technology but also represents an important advancement for China in the field of carbon capture and utilization in power plants.
The assessment, organized by the China Petroleum and Chemical Industry Federation (CPCIF), included an on-site operational evaluation, during which all key performance indicators of the system met design specifications. The average carbon dioxide capture rate exceeded 95%, with peak rates surpassing 99%. Additionally, the conversion rates for hydrogen and carbon dioxide were above 99%, and methanol selectivity was also greater than 99%. Compared to traditional coal-to-methanol processes, energy consumption was reduced by over 70%. These indicators position the project at the forefront of industry standards.
The core technology for this project stemmed from a strategic collaboration between East China University of Science and Technology and Shenergy Group. Wison Engineering managed the project lifecycle, overseeing everything from process package development and design to procurement, construction, and plant operation. The facility effectively integrates a highly efficient CO2 capture unit with an innovative CO2 hydrogenation to methanol process unit, achieving successful commissioning in a single trial run and quickly fine-tuning to meet design capacity for methanol aqueous solution production. This accomplishment highlights the technical expertise and execution capabilities of the project team.
Wison Engineering won the EPC project bid in January 2024, receiving government environmental approval in April, followed by the commencement of on-site detailed surveys a week later. With a stringent schedule mandating "December commissioning", the project team meticulously coordinated all aspects including R&D, design, procurement, and construction under the support of the company. By May, pile foundation work was complete, civil construction began in June, installation started by late August, single-unit testing commenced in November, and integrated commissioning took place in early December. The project was successfully trialed on December 23rd, after extensive preparation. Throughout the process, the project department exhibited a strong sense of responsibility and commitment, efficiently navigating challenges such as plum rain seasons, high-temperature conditions exceeding 40 degrees Celsius, and typhoons, all while adhering to safety and quality standards. Through effective collaboration with stakeholders, including the technology patentee and the owner, Wison Engineering ensured seamless coordination with the capture unit EP provider and the supervisory unit. Drawing on the extensive experience of the plant start-up unit, the operation team was proactive in designing the commissioning schedule, emergency response plans, and other necessary preparations, which facilitated the steady advancement of the trial operation. After optimization efforts, the facility successfully transitioned to a continuous and stable testing phase, culminating in the successful completion of the 72-hour assessment by the CPCIF.
