In January 2007, it was first applied to the "Shell" pulverized coal gasification ammonia synthesis device in Liuhua, Guangxi, creating the world's first application in the "pulverized coal gasification" ammonia production device. Operation data shows that a ton of ammonia consumes medium-pressure steam. 1.013 tons, which saves 2.227 tons of steam compared with the high water/gas process. Not only the operation of the device is stable and safe, but also the energy saving effect is significant, and the total annual economic benefit is 76.9123 million yuan.
The successful application of QDB series catalysts and pulverized coal gasification low water/gas sulfur-tolerant shift process in Liuhua, Guangxi, solved the problem of high-concentration CO raw gas shift reaction, stabilized the shift operation, and significantly reduced steam consumption and process condensate emissions, achieving innovation and breakthrough in sulfur-resistant conversion technology.
