Pyrolysis Furnace For Ethylene Production

Pyrolysis Furnace are important pieces of equipment used for large scale ethylene production. It usually consists of a light diesel cracker and an ethane cracker. By heating the ethylene feedstock at high temperature to decompose the reaction. Thus, ethylene and other chemicals are obtained. Torture stomach box-type heating furnace. Make light diesel oil as raw material. Then after cracking to get separated methane return to the pyrolysis furnace to crack. Thus getting ethylene, propylene, petrol and other raw materials.

Ethylene pyrolysis furnace is usually composed of: furnace body, burner, burner, heat exchanger, control system and other components. The furnace body is the core of the ethylene cracker. It is often made of metal or ceramic material. It has very high heat and corrosion resistance. Light diesel oil and ethane are preheated, light diesel oil and ethane pyrolysis furnace for cracking. The feedstock is vapourised before feeding. The material outlet of light diesel oil pyrolysis is up to 798℃. And the material outlet temperature in the ethane pyrolyser is: 847°C. The pyrolysis gas is cooled to 450~550°C and 350~450°C in the corresponding waste heat kettles. The gas from the waste heat pot is then cooled, compressed and dried in a series of processes. High purity C2H4/C3H5 is produced.

Light diesel oil pyrolysis furnace and ethane pyrolysis furnace body structure is similar. Usually consists of: convection section and radiation section. The two stages do not value are not vertically overlapping. Instead, there is a horizontal turning section. The two stages are not vertically overlapping, but have a horizontal turn section, which is connected by a through column. The convection section is provided with convection tube bundles. Both ends have elbow boxes. The flue gas waste heat after combustion in the radiation section is used to heat the light hydrocarbon medium in the convection tube bundle. A collector is provided on top of the convection section. It will also be equipped with two flue channels on top to bring together an induced draft fan. The outlet is connected to the chimney. The radiant section is fitted with a vertical furnace tube. Cracking medium light hydrocarbon heating and reflecting parts. The intracranial temperature can reach: 1260℃. Both side walls and the bottom are installed in the oil and gas nozzle.
