Method for producing conjugated diene |
| abstract |
[PROBLEMS] To produce a conjugated diene more stably without producing piping blockage due to precipitation of a high-boiling by-product in the production of a conjugated diene by oxidative dehydrogenation of a monoolefin having 4 or more carbon atoms. It is to provide a way to do. A reaction step of obtaining a reaction product gas containing a conjugated diene by subjecting a raw material gas containing a monoolefin having 4 or more carbon atoms to an oxidative dehydrogenation reaction with a molecular oxygen-containing gas in the presence of a catalyst, and the reaction product gas And a cooling step for cooling the conjugated diene, wherein the cooling step supplies the coolant to the cooling tower, contacts the reaction product gas, and then heats the coolant discharged from the cooling tower. A method for producing a conjugated diene, which is cooled by an exchanger, precipitates dissolved in the coolant are deposited and collected in the heat exchanger, and the coolant after the precipitates are collected is circulated to the cooling tower. .
