Abstract

The present invention relates to an absorption device with opposing-placed spraying liquid inlets and a process for producing nitrile. The absorption device can maximize the ammonia absorption rate and reduce ammonia breakthrough. The absorption device of the present invention comprises a shell and a plurality of spraying devices arranged in layers along the central axis direction of the absorption device at predetermined vertical spacings, wherein each of the spraying devices independently 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, perpendicularly to the first spraying pipe, arranged along both sides thereof, a plurality of third spraying pipes in fluid communication with the second spraying pipes and, perpendicularly to the second spraying pipes, arranged along both sides thereof, and nozzles located at the ends of the third spraying pipes and in fluid communication therewith, wherein when a cross-section is obtained by cutting the absorption device at a direction perpendicular to the central axis of the absorption device, at least one selected from the group consisting of the first spraying pipe, the second spraying pipes, and the third spraying pipes of one of the plurality of spraying devices and at least one selected from the group consisting of the first spraying pipe, the second spraying pipes, and the third spraying pipes of another of the plurality of spraying devices substantially coincide in terms of the projection on the cross-section, and the angle between the projections of the spraying liquid inlet of the one spraying device and the spraying liquid inlet of the another spraying device on the cross-section is 180°.
