Cracking furnace is widely used in the following industries:
1. petrochemical industry: it is the key equipment for the production of ethylene, propylene and other olefins. Through pyrolysis of naphtha, light diesel and other petroleum fractions at high temperature, ethylene can be produced in large quantities, and a series of polymer materials such as polyethylene, polyvinyl chloride and polystyrene can be extended, which are widely used in packaging, construction, automobile, electronics and other industries. Propylene is the raw material for the production of polypropylene, acrylonitrile, propylene oxide and other important chemical products, which is widely used in the fields of synthetic fibers, plastics, rubber and so on.
2. coal chemical industry: it can be used in the process of coal to olefin and coal to natural gas. Coal to olefin technology is to convert coal into methanol, and then produce ethylene, propylene and other olefin products through high-temperature cracking of methanol, which helps to reduce the dependence on imported oil and ensure energy security and stable supply of chemical raw materials. In the process of coal to natural gas, high temperature cracking furnace can crack some by-products in the process of coal conversion to improve the quality and calorific value of product gas.
3. natural gas chemical industry: acetylene, syngas and other important chemical raw materials can be produced from natural gas by high-temperature pyrolysis. Acetylene can be used to produce PVC, vinyl acetate and other products, and is widely used in plastics, chemical solvents and other fields; Syngas (the mixture of carbon monoxide and hydrogen) is the basic raw material for the synthesis of ammonia, methanol, dimethyl ether and many other chemical products, which further expands the chemical utilization of natural gas and improves the added value of natural gas resources.
4. environmental protection: organic wastes such as waste plastics and rubber can be cracked and transformed into reusable fuels and chemical raw materials, so as to realize the recycling of resources and reduce environmental pollution.
5. biomass energy utilization: agricultural and forestry wastes such as straw and sawdust are pyrolyzed in a high-temperature pyrolysis furnace at a temperature range of 500-800 ℃ to produce biochar, bio oil and combustible gases. Biochar can be used to improve soil fertility and water retention; After upgrading, bio oil is expected to become a clean energy alternative to fossil fuels; Combustible gas can be directly burned for heat supply or power generation.
