Abstract
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.
Claims7
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.
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.
