Energy Optimization and Alternative Solutions with Semi Coke
Metallurgical Industry
In the metallurgical industry, semi-coke can be used as a blast furnace injection material and a reducing agent for ferroalloys.
Blast Furnace Injection Material:
Feasibility of Semi-coke as Injection Material:
Semi-coke can effectively replace anthracite as an injection material in blast furnaces. Tests confirm that semi-coke powder is technically feasible, with a practical injection ratio of 15% to 30%, making it a viable option.
Benefits in Blast Furnace Operation:
Due to its high fixed carbon content and strong chemical activity, semi-coke functions as a heat source, reducing agent, and carburizing agent in the blast furnace. This allows for the substitution of coke, resulting in energy savings and reduced consumption.
Environmental and Operational Advantages:
With its low ash and sulfur content, semi-coke improves blast furnace production efficiency. It reduces the coke ratio, cuts down desulfurization energy usage, and enhances both operational efficiency and environmental performance, making it a more sustainable choice.
Ferroalloy Plants
Reducing Electricity and Coke Consumption:
In ferroalloy production, replacing metallurgical coke with semi-coke can greatly reduce electricity and coke consumption. This results in lower energy costs and a more efficient production process, while optimizing resource use without compromising production quality.
Enhanced Reducing Properties of Semi-coke:
Semi-coke’s high carbon content and strong reducing properties make it an ideal reducing agent for ferroalloy production. It effectively facilitates the reduction of metal ores, improving overall process efficiency and the quality of the end product.
Impact on Furnace Output:
The use of semi-coke instead of metallurgical coke leads to increased furnace output. Its efficient reduction reaction helps stabilize furnace operations, boosting yields and lowering costs per unit of ferroalloy produced. This enhances both the economic and technical performance of ferroalloy manufacturing.
Chemical Industry
semi-coke can be used as a reducing agent for calcium carbide, a raw material for fertilizer gas production, and a feedstock for gasification to produce syngas.
Calcium Carbide Reducing Agent
Ideal for Calcium Carbide Production:
Semi-coke’s low ash, aluminum, phosphorus content, and high resistivity make it a highly effective reducing agent in calcium carbide production.
Energy and Cost Savings:
Using semi-coke reduces energy consumption and lowers production costs, making it a more economical choice.
Improved Product Quality:
Semi-coke enhances the quality of calcium carbide, resulting in a more consistent, higher-grade product.
Fertilizer Gas Production Raw Material
Enhanced Gas Production:
Low ash and sulfur content in semi-coke boost gas production rates, improving efficiency in fertilizer gas production.
Lower Ash Emissions:
Semi-coke reduces ash emissions, making the process cleaner and more environmentally friendly.
Decreased Desulfurization Needs:
Reduced sulfur content lowers desulfurization requirements, saving energy and improving gas quality.
Gasification for Syngas Production:
Reduced Tar Content:
Semi-coke gasification produces syngas with less tar, improving syngas quality.
Higher Useful Gas Content:
Gasification of semi-coke results in a higher yield of valuable gases like hydrogen and carbon monoxide.
Less Burden on Purification:
Lower tar content reduces the strain on gas purification units, enhancing process efficiency and lowering maintenance costs.
Clean Fuel Field
Semi-coke, as a clean fuel, can replace traditional coal and oil.
Residential Fuel
- Low Pollutant Content: Semi-coke has only one-fifth of the pollutants found in raw coal.
- Lower Sulfur Levels: The sulfur content in semi-coke is only one-tenth of that in raw coal, making it less harmful to health and the environment.
- Clean Energy Alternative: Semi-coke is an ideal clean fuel for residential use, helping to reduce indoor air pollution.
- Replacement for Smokeless Coal: It can replace smokeless coal in both urban and rural areas, contributing to cleaner air and reducing emissions.
Power Plant Fuel
- Low Ash and Sulfur Content: Semi-coke’s low ash and sulfur characteristics make it a cleaner alternative to traditional coal.
- Reduced Emissions: These properties help to lower the amount of harmful pollutants released during combustion.
- Improved Environmental Quality: Using semi-coke in power plants helps improve overall environmental conditions by reducing emissions.
- Fuel Substitution: Semi-coke can effectively replace traditional coal in power generation, reducing the environmental footprint of the power industry.
