CO Recovery from N2-Rich Gases
Separation of CO from N2-rich gases is difficult throughout the world. With the exclusive PU-1 adsorbent and the associated separation process, PKU Pioneer has realized the technological breakthrough of purifying CO from nitrogen-enriched gas mixtures, which has provided key technological support for the development of the steel and chemicals co-production projects.
BFG and BOFG Purification
PKU Pioneer initiated the process blast furnace gas and converter gas purification process in the industry- "compression-desulfurization-deoxygenation-dehydration-carbon capture-CO purification". Having been successfully industrialized, the process will further improve the efficiency of the cogeneration of the steel and chemicals co-production with low energy consumption and advanced technologies.
Benefiting Carbon Capture
With 20-30% CO2 content in the blast furnace and converter gas, decarbonization (carbon capture) is necessary for recovering high-purity CO from BFG and BOFG. Therefore, combining steel and chemical production reduces the cost and energy consumption of carbon capture for the iron and steel industry.
Significant Economic Benefits
Compared with modern coal chemical industry, the steel-chemical co-production replaces coal gasification with steel exhaust gases, which reduces the raw material cost of chemical engineering and avoids the risk arising from coal price fluctuation, making the price of terminal chemical products more competitive.
Outstanding Environmental Benefits
Steel-chemical co-production immobilizes CO originally used for combustion into chemical products, and simultaneously carries out performs purification processes such as dust removal and desulfurization, reducing emissions of carbon, sulfur and nitrogen oxides and other pollutants emitted by iron and steel enterprises to achieve ultra-low emissions and “dual carbon” target.
Significant Social Benefits
As a coordinated solution that surpasses the limitations of a single industry, steel-chemical co-production helps to extend the industrial chain of the steel industry, improve the risk-resistant ability, expand the raw materials for the chemical industry, enhance product competitiveness, and promotes the transformation and upgrading of industry integration.
