Abstract
Provided is an NMP recovery systemfor causing NMP-containing gas to contact NMP-absorbing water, including: fillers (A) to (D) 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 () for distributing the NMP-containing gas so as to cause the NMP-containing gas to contact the water held by the fillers (A) to (D); and a water distribution unit () for distributing the water so as to make the water permeate through the fillers (A) to (D). In the fillers (A) to (D), 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.
