1. A Case Study on CCUS

By Zhang Yongjie, Chief Scientist of Baosteel Research Institute

According to the data from World Steel Association, the global steel production in 2017 was 1.689 billion tons, with more than 3.2 billion tons of carbon dioxide emissions. At the end of 2017, G20 Ministers reached a consensus on reducing steel excess capacity. In China, steel output was 831.7 million tons, accounting for about a half of the global steel production. China has been increasingly strict in emission reduction.

Baosteel was ranked the second large manufacture in global steel production. It has persisted energy saving and emission reduction since it was born. In recent years, it initiated CCUS technology research and practice, and innovated energy saving management. The experiment was called Bao-CCU by the World Steel.

Bao-CCU includes: 1) after the analysis of ULCOS and Course50, Baosteel chose blast furnace gas to capture carbon dioxide; 2) after technical modular comparison and selection, Baosteel proposed to use the waste heat resource to implement carbon separation -- chemical absorption method instead of pressure swing adsorption; 3) at same time, calorific value of blast furnace gas upgraded that could increases the output of power plant output; 4) CO2 could be used in steelmaking process, microalgae cultivation, carbon sequestration to obtain biofuels, and as a technical solution to partially replace nitrogen.

2. Technical Research and Practice on Low Carbon and Energy Efficiency in Steelmaking  

A book named《钢铁低碳高能效共性难题技术研发与应用》in Chinese published by  Metallurgical Industry Press in August 2019.

Authors:  Zhang Yongjie, Chief Scientist of Baosteel Research Institute, with Dr. Huang Jun, Inner Mongolia University of Science and Technology, et al. 

 
After decades endeavor, combining local and global advanced knowledge and practical experience, Baosteel achieved a lot in steelmaking technically and economically. The book summarizes the latest development trends of typical common problems of low-carbon and energy efficiency in steelmaking, presents Baosteel upgraded theoretical minimum energy models, and 10 R&D cases with technical solutions.
