**Evaluation Meeting for the Project under the Key R&D Program titled “Development and Demonstration of Large-Scale Water-Coal Slurry Gasification Technology” Held Author/Source: Gasification World Date: 2021-07-12 Views: 145 On July 9, 2021, the evaluation meeting for the project under the Key R&D Program “Development and Demonstration of Large-Scale Water-Coal Slurry Gasification Technology”, which is led by Shandong Energy Group, was successfully held at Inner Mongolia Rongxin Chemical Co., Ltd. **More than 40 people attended the meeting, including project managers from the High-Tech Center of the Ministry of Science and Technology, relevant experts, representatives from energy groups, energy and chemical companies, and representatives from 15 other organizations. The meeting appointed Professor Shui Hengfu from Anhui University of Technology as the head of the expert team. The meeting heard summary reports from the representatives of the five projects on the progress of their research and development work, the achievements obtained, funding expenditures, as well as the social and economic benefits, and reviewed relevant materials such as the project performance evaluation reports. After thorough research and discussion by the experts present, an evaluation conclusion was reached. The expert group has consistently held that the performance evaluation materials are complete and meet the evaluation requirements; the research tasks specified in the project plan were fulfilled, and the assessment criteria were satisfied, with the project management being systematic and orderly. The project \"Development and Demonstration of Large-Scale Water-Coal Slurry Gasification Technology\" was approved under the Key R&D Program in 2017. Through years of research, a series of fundamental theoretical achievements have been developed, including the laws governing the migration of trace elements during the water-coal slurry gasification process and testing methods for the viscosity-temperature properties of coal ash under steam conditions. Process design software packages for ultra-large multi-nozzle opposed water-coal slurry gasification industrial units as well as waste boiler-cooling type high-efficiency water-coal slurry gasification industrial units have been created. Moreover, a demonstration industrial unit for multi-nozzle opposed water-coal slurry gasification capable of processing 4,000 tons of coal per day per furnace has been built and brought into stable operation. On January 25, 2021, the demonstration unit passed a 72-hour on-site assessment organized by the Petrochemical Federation, with its results exceeding significantly the technical specifications set out in the Project Plan. From January 23 to 25, 2021, the 4,000-ton multi-nozzle gasification unit of Inner Mongolia Rongxin Chemical Co., Ltd. underwent a 72-hour performance test. The organization responsible for conducting the assessment is the China Petroleum and Chemical Industry Federation. An expert team conducted on-site inspections of the coal slurry preparation system, gasification and preliminary gas purification system, and slag treatment system of Rongxin Chemical’s 4,000-ton gasification plant. They also inspected the control room, analysis laboratory, and sites for sample collection, to ensure that the data collected as part of this assessment are accurate and reliable. Following the evaluation, the expert panel unanimously agreed that during the 72-hour testing period, the demonstration unit operated smoothly, and the various measurement data obtained were accurate and reliable. Both the coal consumption and oxygen consumption, as well as the carbon conversion rate, exceeded the specified criteria. By carrying out research on high-pressure process enhancement, scaling up of the gasifier, structural optimization, improvement of the refractory lining, and optimization of the burner design, the multi-nozzle opposed water-coal slurry gasification technology enabled industrial operation with a capacity of 4,000 tons of coal per day per unit, building upon existing industrial gasifiers with capacities of 1,000 tons, 2,000 tons, and 3,000 tons per day per unit; as a result, the unit passed the evaluation.
