Abstract
A dehydration method by which water is selectively separated from a water-containing mixturewith a separation membrane. The separation membrane is a DDR type zeolite membrane. The dehydration method includes bringing the mixtureinto contact with one side of the DDR type zeolite membraneand causing a pressure difference between that side of the DDR type zeolite membranewhich is in contact with the mixture and the other side of the DDR type zeolite membraneto thereby cause the water to selectively permeate and separate out. By the dehydration method, water can be selectively separated from a water-containing mixture without the need of a high energy cost. The separation membrane has excellent acid resistance.
