<P>PROBLEM TO BE SOLVED: To provide a multi-tube separation membrane module that can supply a sweep gas, having the effect of reducing the partial pressure of a penetrating component on the secondary (penetration) side of a membrane, to the inside of each tubular membrane element even when using a membrane module mounted with a plurality of tubular membrane elements whose one end is sealed and whose other end is opened. <P>SOLUTION: In the multi-tube separation module 1, a sweep gas injection pipe 3 is inserted into the inside of each tubular membrane element 2 from the open end 2b of the membrane element 2, the tip 3a of the sweep gas injection pipe 3 is opened inside a part closer to the sealed end 2a of the membrane element 2, sweep gas sent into each sweep gas injection pipe 3 from a sweep gas introducing part is supplied from the open tip 3a of the sweep gas injection pipe 3 into the inside of the part closer to the sealed end 2a of the membrane element 2, a component penetrated from each membrane element 2 is diluted by the sweep gas in the inside of the membrane element 2, and the partial pressure of the penetrating component is lowered and a mixed component of the penetrating component and the sweep gas are discharged. <P>COPYRIGHT: (C)2013,JPO&INPIT |
