工业尾气变成干净原料 我国首个焦炉煤气100%转化项目落地

Core Insights - The first 100% conversion project of coke oven gas in China has been established in Lingyuan, Liaoning, marking a significant step towards green and low-carbon development in the steel industry [1][7]. Group 1: Project Overview - The project utilizes advanced separation and synthesis technology to convert coke oven gas into LNG (liquefied natural gas), liquid ammonia, and hydrogen, achieving a complete conversion of waste gas into valuable resources [1][3]. - The annual production of coke oven gas in China is approximately 210 billion cubic meters, and utilizing 30% of this could reduce carbon dioxide emissions by about 45 million tons annually while generating over 100 billion yuan in industrial output [7]. Group 2: Economic and Environmental Impact - The conversion of coke oven gas into hydrogen has a cost advantage, being 30% to 50% cheaper than traditional coal or natural gas hydrogen production methods, which is driving rapid market growth [8]. - The produced LNG can provide heating for around 200,000 households for a month, while liquid ammonia can be further processed into fertilizers, refrigerants, and even rocket propellants [9]. Group 3: Technological Advancements - The purity of hydrogen produced from coke oven gas has improved from 99.999% to 99.9999%, which is crucial for applications in high-end manufacturing sectors such as electronics, aerospace, and advanced chemicals [12][14]. - The core technology relies on a new type of molecular sieve that selectively allows hydrogen to pass through while trapping impurities, enhancing the quality of the hydrogen produced [14].
