GAS-LIQUID CONTACT DEVICE, DISTILLATION DEVICE, AND HEAT EXCHANGE DEVICE

摘要

Provided is an NMP recovery system 1 for causing NMP-containing gas to contact NMP-absorbing water, including: fillers (10A) to (10D) that are permeable to the water and hold the water, wherein the permeated water moves according to gravity to flow out from the fillers; an NMP-containing gas distribution unit (30) for distributing the NMP-containing gas so as to cause the NMP-containing gas to contact the water held by the fillers (10A) to (10D); and a water distribution unit (40) for distributing the water so as to make the water permeate through the fillers (10A) to (10D). In the fillers (10A) to (10D), the NMP-containing gas is made to contact the NMP-absorbing water. Accordingly, NMP in the NMP-containing gas is absorbed in the water, so that the NMP is separated from the NMP-containing gas.

1. A gas-liquid contact device for causing gas containing an absorbable material to contact liquid absorbing the absorbable material, comprising:
a filler that is permeable to the liquid and holds the liquid, wherein the permeated liquid moves according to gravity to flow out from the filler; a gas distribution unit for distributing the gas so as to cause the gas to contact the liquid held by the filler; and a liquid distribution unit for distributing the liquid so as to make the liquid permeate through the filler, wherein in the filler, the gas containing the absorbable material is made to contact the liquid absorbing the absorbable material; and the absorbable material included in the gas is absorbed in the liquid and is separated from the gas.
