Steel and Chemicals Co-Production
Bridging the gap between heavy industry and chemical synthesis to drive the global transition toward a low-carbon future through innovative resource utilization.
Quantifying the Industrial Impact
Our technology leverages the massive scale of existing steel production to create a sustainable chemical feedstock.
China's annual steel production capacity, providing a vast source of by-product gases.
Average carbon dioxide concentration in blast furnace and converter gases.
Successfully completed large-scale industrial implementations across major steel groups.
Path towards ultra-low industrial emissions and the realization of "dual carbon" targets.
The Bridge Between Two Giants
China's steel production capacity exceeds 1 billion tons per year. A large amount of blast furnace gas (BFG), converter gas (BOFG) and coke oven gas (COG) is produced as by-products of the iron and steel production process, where CO, H2 and methane are contained.
C1 chemistry is a production process that converts and synthesizes chemical products from compounds of one carbon atom (CO, methane, etc.) as raw materials. Modern coal-chemical processing, which uses syngases mainly containing CO and H2 as the feedstock, is the most typical application.
CO and H2 are purified from the steel by-product gases and used directly in the C1 chemistry, which not only increases the utilization value of the steel gases but also reduces the production cost of chemical synthesis. It is one of the effective ways for the steel industry to realize the "dual carbon" goals.
Innovative Low-Carbon Solutions for a Sustainable Future
CO Recovery from N2-Rich Gases
Separation of CO from N2-Rich Gases is difficult throughout the world. With the exclusive PU-1 adsorbent, PKU Pioneer has realized the technological breakthrough of purifying CO from nitrogen-enriched gas mixtures.
BFG and BOFG Purification
We initiated the industry-leading purification process: "compression-desulfurization-deoxygenation-dehydration-carbon capture-CO purification". Successfully industrialized with low energy consumption.
Benefiting Carbon Capture
With 20-30% CO2 content in the blast furnace and converter gas, decarbonization is necessary for recovering high-purity CO. This model reduces the cost and energy consumption of carbon capture.
Significant Economic Benefits
Replaces coal gasification with steel exhaust gases, reducing raw material costs and avoiding coal price fluctuation risks, making terminal chemical products more competitive.
Outstanding Environmental Benefits
Immobilizes CO into chemical products while performing purification processes like dust removal and desulfurization, reducing emissions of carbon, sulfur, and nitrogen oxides.
Significant Social Benefits
A coordinated solution that surpasses industry limitations, extending the steel industry's value chain and promoting the transformation and upgrading of industry integration.
Versatile Industrial Integration
Foundry Blast Furnace Ironmaking
Generally, casting blast furnaces with useful volumes smaller than 1000m³ are used. CO can be purified and used to produce formic acid, acetic acid, and dimethyl carbonate.
Long Process Steelmaking
Enterprises adopt blast furnaces (1000-6000m³) and converters (30-350 tons). CO can be purified for chemical products with H2 excluded in the synthesis.
Steel and Coke Chemical Enterprises
Conglomerates equip coke ovens (4.3-7.6m) to manufacture coke. H2 can be purified for production of chemical products requiring H2 when synthesizing with CO.
Independent Coking Enterprises
Enterprises use coke ovens (4.3-7.6m) to manufacture coke. Methane in the COG can be reformed into syngas containing CO and H2 for separation.
