Jingyuan has entered the trial operation phase! Construction progress of Phase I of the Comprehensive Utilization of Clean and Efficient Gasified Coal Power Gas Project (Relocation and Renovation)

The detailed engineering design, supervision, cost consulting, and follow-up auditing for various units of the project’s Phase II are progressing as scheduled. The civil construction work has already begun in full scale, and the bidding process for the long-life equipment has been completed; these devices are currently under production. Plan to complete the bidding process for the remaining equipment and materials during the winter construction shutdown period. We will step up efforts to organize the construction work once next spring arrives. It is reported that the gasification unit uses the HT-L pressurized coal gasification technology to produce crude syngas, with a production capacity of 120,000 Nm³/h of usable gas. The production process includes tasks such as the storage and transportation of fuel coal, coal grinding and drying, coal pressurization and transportation, gasification and syngas washing, as well as the treatment of slag and ash water. Project Overview: The Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization (Relocation and Renovation) project has a total investment of 5.425 billion yuan. It is located in the Yindong Industrial Park of the Baiyin High-Tech Industrial Park, covering an area of 839 mu. The raw coal and fuel coal used in the project are mainly Jingyuan coal, and advanced, mature, and energy-saving technologies such as pressurized coal gasification, isothermal shift, and Claus sulfur recovery are employed to produce products such as synthetic ammonia, methanol, urea, melamine, and urea ammonium nitrate solution ； At the same time, it supplies high-quality raw materials such as hydrogen and carbon monoxide to other chemical enterprises in the Yindong Industrial Park, thereby promoting the development of a circular economy in the park. The first phase of the Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization Project has an annual production capacity of 300,000 tons of synthetic ammonia, 350,000 tons of urea, 20,000 m3/h of (H2+CO), 40,000 tons of methanol, 50,000 tons of liquid carbon dioxide, 60,000 tons of melamine, 50,000 tons of urea-ammonium solution, 1,924 tons of sulfur, and 2,500 tons of catalysts. The second phase of the project results in an annual production capacity of 300,000 tons of ammonia, 350,000 tons of urea, 10,000 m3/h of (H2+CO), and 60,000 tons of methanol.

On October 27, the 40,000 Nm3/h air separation unit of Phase I of the Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization (Relocation and Renovation) project was successfully commissioned for the first time, producing qualified oxygen and nitrogen products. Image: This air separation unit utilizes low-temperature air separation technology and includes components such as an air compression system, a pre-cooling system, a molecular sieve purification system, a heat exchange system, a refrigeration system, a distillation system, and a backup system. It features good safety performance, high reliability, and significant energy-saving effects. Its main functions are to supply instrument air, process air, oxygen, and nitrogen throughout the plant, while also producing products such as liquid oxygen, liquid nitrogen, and liquid argon.

On the morning of October 31, the launching ceremony for the single-unit trial operation of Phase 1 of the Clean and Efficient Gasification and Comprehensive Utilization (Relocation and Renovation) project of Jingyuan Coal and Electricity at Gansu Nenghua Co., Ltd. was held. The project has successfully entered the trial operation and debugging phase, and construction of Phase 2 has also begun in full swing, marking an acceleration in the development of the company’s coal chemical industry base in the Baiyin High-Tech Industrial Park. The total investment in project planning is 5.425 billion yuan, with a land area of 839 mu. In terms of process technology, equipment selection, and environmental protection measures, the most advanced energy-saving technologies and treatment methods available internationally and domestically are employed. Advanced and mature technologies such as pressurized coal gasification, isothermal shift, low-temperature methanol washing, Claus sulfur recovery, liquid nitrogen washing, low-pressure ammonia synthesis, and carbon dioxide stripping for urea production are employed to manufacture products including synthetic ammonia, methanol, urea, melamine, and urea-ammonium nitrate solutions ； At the same time, it provides high-quality raw materials such as hydrogen and carbon monoxide to the enterprises located in the park, thereby forming an upstream and downstream industrial chain. The flue gas emissions from the project meet ultra-low emission standards, while wastewater is treated to achieve near-zero emissions. Solid waste such as ash and slag is comprehensively utilized in accordance with the principles of reduction, resource utilization, and harmlessness, thereby maximizing resource use and minimizing pollutant emissions and effectively promoting the development of a circular economy in the industrial park.

On April 15, the lifting of the coal powder storage tank for the Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization (Relocation and Renovation) project was completed successfully, marking the project’s smooth entry into the intensive pipeline installation phase. The coal powder storage tank to be lifted this time is the first custom-made equipment fabricated on-site. It is 18 m high and weighs 62 t; its installation height is 60 m. The lifting operation was carried out using an 800 t crawler crane as the main lifting device and a 70 t truck crane for assisting in the lift. The equipment was successfully lifted at 10 a.m., and was installed in one go by 12 p.m., thus fulfilling the installation deadline target and earning unanimous approval from the owner and the general contractor.

On May 4, 2024, the core equipment of the purification and synthesis unit in Phase I of the Jingyuan Coal and Electricity Clean and Efficient Gasification Gas Comprehensive Utilization (Relocation and Transformation Project), namely the shift gas scrubber (220-C-1101), was successfully lifted into place. The equipment has a diameter of 3.6 meters, a height of 87.86 meters, a net weight of 469 tons, and a total lifting weight of up to 689.8 tons; its weight and length rank it first among the equipment used in Phase 1 of the project. To reduce the safety risks associated with work at heights and improve construction efficiency, the contractor developed a specialized lifting plan which was reviewed by experts. Before carrying out the lifting operation, the workers were given technical instructions, and the necessary work permits were obtained in accordance with regulations; the lifting was performed by first securing the structure on the ground with appropriate supports before lifting it as a whole. The lifting machinery consisted of a 2,000-ton crawler crane as the main lifting device and a 650-ton crawler crane as an auxiliary device, working together in coordination. Thanks to the careful organization and efforts of all the personnel involved in the project, the gas scrubber was successfully lifted into place, laying the foundation for subsequent installation work.
