Abstract
Official abstract text for this publication.
A dehydration method is a dehydration method for selectively separating water from a mixture that contains water, and the method includes a step of supplying the mixture to a supply side space of a zeolite membrane having an ERI structure, and a step of making a pressure difference between the supply side space and a permeation side space of the zeolite membrane having an ERI structure.
First claim
Opening claim text (preview).
1 . A dehydration method for selectively separating water from a mixture that contains water, using a zeolite membrane having an ERI structure, the method comprising: a step of supplying the mixture to a supply side space of the zeolite membrane having an ERI structure; and a step of making a pressure difference between the supply side space and a permeation side space of the zeolite membrane having an ERI structure. 2 . The dehydration method according to claim 1 , wherein the zeolite membrane having an ERI structure contains at least two elements out of Si, Al, and P. 3 . The dehydration method according to claim 2 , wherein the zeolite membrane having an ERI structure contains at least Al, P, and O. 4 . The dehydration method according to claim 1 , wherein the zeolite membrane is formed on a porous support. 5 . A dehydration apparatus comprising: a separation vessel configured to include a porous support, a zeolite membrane having an ERI structure that is formed on the porous support, and a housing portion that is sectioned into a supply side space of the zeolite membrane having an ERI structure and a permeation side space of the zeolite membrane having an ERI structure; and a pressure changing apparatus configured to increase a pressure in the supply side space and/or reduces a pressure in the permeation side space. 6 . The dehydration apparatus according to claim 5 , wherein the zeolite membrane having an ERI structure contains at least two elements out of Si, Al, and P. 7 . The dehydration apparatus according to claim 6 , wherein the zeolite membrane having an ERI structure contains at least Al, P, and O.
