STRATEGY OF CLEAN AND EFFICIENT USE OF CHINA'S MODERN COAL CHEMICAL INDUSTRY
Grouping of carbon capture,utilization and storage(CCUS)is a key path to clean and efficient use of modern coal chemical industry.China's current coal chemical industry has problems in increasing carbon emission intensity and high carbon reducing costs.This paper,based on the current status of China's modern coal chemical industry in production or producing capacity from producing,developing and planning projects,uses carbon dioxide capturing potential model and CCUS sourcing & sinking matching model to study the distribution,carbon emission,and carbon dioxide capturing potential,sourcing and sinking,and entire-process costs of CCUS projects.China's modern coal chemical industry has formed in a layout of west Inner Mongolia,Shaanxi,Shanxi and Ningxia as the center,Xinjiang and Qinghai as the supplement,and east coast as the extension.Carbon emission of China's modern coal chemical industry shows a directly rising trend if considering the developing and planning projects,up to 263.88 million tons by 2020 from the developing projects,and up to 644.79 million tons from the planning projects.By 2020,carbon dioxide capturing potential of CCUS projects is up to 556.22 million tons annually,of which Inner Mongolia,Shaanxi,Xinjiang and Shanxi seat on the top,up to 148.73,99.88,80.88 and 40.00 million tons respectively.On the basis of carbon dioxide capturing scales and pipe transporting economy,sourcing and sinking match is found well in Inner Mongolia &Shaanxi to Ordos basin,Shandong to Bohai bay basin,Xinjiang to Ordos and Junggar basin,Jiangsu & Zhejiang to Subei basin.Shaaxi,Shangdong,Jiangsu and Zhejiang are suitable for prioritizing the use of modern coal chemical industry CCUS technology from the entire process costs,carbon capturing potentials and sourcing & sinking match.
