【HaiChuan Chemical Discussion】Shaanxi Coal Yulin Gasification adopts Collin CCG top-mounted multi-nozzle dry powder coal gasification technology
Thread Content
The gasification unit of the first phase of Shaanxi Coal Yulin Chemical’s 1.8 million tons per year ethylene glycol production project utilizes Collin CCG top-mounted multi-nozzle dry powder coal gasification technology. The unit is capable of producing over 700,000 standard cubic meters of syngas per hour, making it the largest Collin dry powder coal gasification demonstration plant in the world at present. Under the EPC general contracting by Tianchenyuan, 5 Colins CCG pulverized coal gasification units with a daily coal input of 2,000 tons each will be used; each unit has an effective dry-base gas production capacity of 140,000 cubic meters per hour. Completion and commissioning are scheduled by the end of June 2021.
In recent years, Yankuang Group has made significant efforts to advance the research and development as well as industrial application of coal gasification technology. In 2014 and 2019, it established industrial demonstration projects for multi-nozzle opposed water-coal slurry gasification at Rongxin Chemical, with capacities of 3,000 tons and 4,000 tons per day respectively. The water-coal slurry hot-wall furnace gasification technology developed by Yankuang Group holds an internationally leading level in terms of intellectual property rights. At present, Yankuang Group is actively planning a 4 million tons per year coal indirect liquefaction project in Yulin, as well as an 800,000 tons per year coal-to-olefins project and a 5 million tons per year coal indirect liquefaction project in Xinjiang. It is using the 3,000 tons per day OMB new-type pulverized coal gasification industrial demonstration project of Lunan Chemical as a pilot project for its western development initiatives, and is accelerating its implementation. This approach serves both to provide a model for the on-site conversion and clean, efficient utilization of low-grade, low-quality coal in Shaanxi, Inner Mongolia, and Xinjiang regions while accumulating relevant experience, and it also represents an important step in implementing the group’s strategy of coordinating resources, technologies, and industries across different regions.
Currently, among the more than 20 gasification technologies available domestically and internationally, the multi-nozzle opposed gasification technology holds a significant market share. In particular, multi-nozzle gasification technology holds an absolute advantage in market share for coal water slurry gasification at 2,000 tons and above. Multi-nozzle gasification technology has become one of the preferred technologies for coal chemical enterprises both domestically and internationally. Multiple coal-water slurry gasification units in Zhenjiang, Jiangsu, including those operated by Supor, have been in continuous operation for over 500 days, setting multiple new world records and reaching an internationally leading level among such units.
German company Collin Industrial Technology GmbH possesses over 40 years of experience in research, development, design, manufacturing, construction, and operation in the field of dry powder gas flow-bed gasification. It holds independent and complete intellectual property rights as well as industrial solutions related to its Collin CCG powder gasification technology. Collin was founded by Dr. Wolf, former head of the R&D department at the German Fuel Research Institute; its core technical team comes from the former German Fuel Research Institute and the Black Water Pump Gasification Plant. In the 1990s, Dr. Wolf and his colleagues founded Corin, and developed the CCG pulverized coal gasification technology based on the 200MW industrial plant for black water pump gasification.
Yulin Energy also uses the same technology
Was this technology chosen based on the characteristics of the coal type?
It is estimated that this is due to coal’s wide adaptability, as well as considerations regarding its gasification rate and operational aspects
With the same location and the same equipment, future maintenance will be much easier; it’s possible to share resources, and effective communication can also be maintained in case of malfunctioning systems
Recently, Colin Future Energy Technology (Beijing) Co., Ltd. reported that following the selection of Colin’s patented dry powder gasification technology for the 1.8 million tons per year ethylene glycol production facility in Phase 1 of the demonstration project on the utilization of coal in various ways by Shaanxi Coal Group Yulin Chemical Co., Ltd., this same technology has been chosen for the gasification process in Phase 1 of the 1.2 million tons per year ethylene glycol production project carried out by Shaanxi Yulin Energy Group Co., Ltd., specifically for the 400,000 tons per year production unit. These two messages indicate that in the Yulin region of Shaanxi, where water-coal slurry holds a dominant position, the Collin dry powder gasification process has emerged as a promising option and has gained recognition from coal chemical enterprises; its advantages in terms of economic efficiency, adaptability to different types of coal, and environmental protection are becoming increasingly evident.
