An ethylene cracking furnace is a device used to produce ethylene. Ethylene is an important chemical raw material, which is usually produced by thermal cracking process. The decomposition of heavy-duty hydrocarbon feedstock, usually petroleum feedstock or natural gas, into ethylene and other by-products. The following is the structure of the ethylene cracking furnace and an introduction to the refractories used in each part of the furnace. Structure of Ethylene Revamp Furnace Heating furnace. The core part of the ethylene cracking furnace is the heating furnace. It is used to provide high temperature and heat energy to promote the decomposition of hydrocarbons. The reactor. The part behind the heating furnace includes the reaction catalyst, such as graphite, metal catalyst, etc. It is used to catalyze the decomposition of hydrocarbons. Separation device. Used to separate the resulting ethylene and other byproducts from the reaction mixture. This usually includes equipment such as cond
