| titleOfInvention | A kind of steam cracking method |
| abstract | A kind of steam cracking method, the method comprises: water vapour and mixed being incorporated in convection zone of liquid cracking stock heat by (1), cracking stock mixture is vaporized and is heated to cross-over temperature, then the cracking stock mixture of vaporization is added in radiation section and carries out the first scission reaction, obtain the first cleavage reaction product; (2) logistics containing alkene is carried out preheating in described convection zone, and the logistics containing alkene after preheating is mixed to carry out the second scission reaction in the exit of described radiation section with described first cleavage reaction product, obtain the second cleavage reaction product, then described second cleavage reaction product is injected described quenching apparatus and carry out refrigerated separation.Described steam cracking method can not only efficient recovery from the heat of the high-temperature split product of radiation section, but also can not cause blocking owing to producing coking in rapid-cooling heat exchanger. |
