Abstract

The present invention relates to a process and device for producing nitrile with controlled input pressure of spray liquid. The producing process can atomize the spray 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, and a step of spraying a spraying liquid onto the reaction product through a spraying device to cool the reaction product, wherein the spraying device comprises a spraying liquid inlet, a first spraying pipe in fluid communication with the spraying liquid inlet, a plurality of second spraying pipes in fluid communication with the first spraying pipe and extending perpendicularly to the first spraying pipe toward both sides thereof, a plurality of third spraying pipes in fluid communication with the second spraying pipes and extending perpendicularly to the second spraying pipes toward both sides thereof, and nozzles located at the ends of the third spraying pipes and in fluid communication therewith, wherein in the cooling step, the spraying liquid input pressure at the spraying liquid inlet is controlled to be 0.06-1.00 MPaG.
