Title:

SEPARATION MEMBRANE MODULE

Document Type and Number:

WIPO Patent Application WO/2023/210803

Kind Code:

A1

Abstract:

A separation membrane module (1) includes a tubular housing (20), a columnar reactor (10) housed in the housing (20), an annular first flange (30) surrounding a first end portion (10a) of the reactor (10), and a first bonding material (35) interposed between the first flange (30) and the reactor (10). The housing (20) has a first facing surface (J1) facing an end surface (K1) of the first flange (30) and an inner circumferential surface (G1) facing an outer circumferential surface (L1) of the first flange (30). A coefficient of thermal expansion of the first bonding material (35) is smaller than a coefficient of thermal expansion of the first flange (30). A coefficient of thermal expansion of the reactor (10) is smaller than the coefficient of thermal expansion of the first flange (30).
