Abstract

The present invention relates to a process for producing a nitrile with improved ammonia absorption effect. The process can atomize the spraying liquid, increase the contact area with ammonia, and improve mass transfer efficiency. The process for producing the nitrile comprises a step of subjecting a hydrocarbon feedstock to ammoxidation reaction to produce a reaction product containing nitrile (called as reaction step), and a step of feeding the reaction product into an absorption device through a gas inlet and spraying a spraying liquid onto the reaction product via a spraying device within the absorption device to cool the reaction product and form an absorption atmosphere (called as cooling step), wherein when measured at a vertical distance of 3000 mm above the gas inlet, the absorption atmosphere has an extinction coefficient of 0.004-0.02 m<-1>.
