Ethylene Cracking Equipment Naphtha (mainly), ethane, ethane/propane, propane, mixed feedstock, butane, LPG, refinery dry gas, diesel fuel, etc.

Steam cracked ethylene is the most important ethylene production path,and the production process mainly consists of steam cracking in tube furnaces and deep-cooling separation. It is divided into three production routes: light hydrocarbon cracking, naphtha-based mixed cracking, and coal chemical route. Other processes are catalytic pyrolysis,catalytic cracking, methanol to olefins are used in related products

Types of Ethylene Cracking Furnace can be technically divided into double-radiation chamber, single-radiation chamber and milliseconds furnace. From the type of furnace can be divided into CBL cracker, SRT cracker, USC cracker, KTI GK cracker, millisecond cracker, Pyrocrack cracker.
Ethylene cracker is divided into convection section and radiation section. The convection section recovers the flue gas waste heat, which is used to preheat and vaporize the feed oil and superheat the feed oil and dilution steam to the material's cross-over temperature, and the remaining heat is used to superheat the ultra-high-pressure steam and preheat the boiler feed water.
In the process of raw material preheating and vaporization, dilution steam is injected to reduce the vaporization temperature of the raw material oil and prevent the raw material oil from coking in the process of vaporization. Cracker convection section of each group of coils mainly by the heat exchanger tube through the back elbow welded into the end of the tube plate and the middle tube plate to support the furnace tube, some of the coils of the import and export through the collection box together. Each set of coils around the perimeter and then grouped on the furnace wall, it constitutes a module. It involves W/U/I type radiant tube steel structure, furnace tube, furnace wall (lining), burner, hole fittings, etc.
