Description

Technical Field

[0001] The utility model relates to the technical field of packed towers, in particular to a random packed tower. Background Art

[0002] A packed tower is a tower with low fluid resistance, suitable for processes with large gas processing volume and small liquid volume. The liquid flows from top to bottom along the surface of the packing, and the gas and liquid flow in countercurrent or parallel, depending on the specific reaction. The amount of liquid in the packed tower is small. Regardless of the gas phase or liquid phase, its flow pattern in the tower is close to piston flow. If solid phase is generated during the reaction process, a packed tower should not be used.

[0003] Announcement No. (CN215352859U) discloses a random packing tower. The fully washed reduced top gas then enters the rosette random packing in the secondary washing section, where it is countercurrently contacted with the lean amine liquid evenly flowing down from the second trough distributor located above it, further removing H2S from the reduced top gas. Finally, the reduced top gas enters the defoaming section. During the operation of the above-mentioned device, the contact time between the reduced top gas and the lean amine liquid is relatively short, which will affect the treatment effect of hydrogen sulfide and needs to be improved.
