NOVELTY - The module (1) has several tubular separation membranes (3) arranged in parallel along the longitudinal direction of housing (2). A support plate (5) which supports the separation membrane, has baffles (7,8) provided with the penetration holes (7a,8a) by which the membranes are penetrated. A boss portion (3c) of membrane is penetrated by the penetration hole of the baffle (7). An end block (3d) is penetrated by the penetration hole of baffle (8). A fluid inflow port (9) is provided so that to-be-processed fluid is introduced between support plate and baffle (7).    USE - Multi-tubular type separation-membrane module for separating specific component in solution or mixture of gas containing components chosen from carbon dioxide, oxygen, nitrogen, methane, ethane, ethylene, propane, propylene, normal butane, isobutane, 1-butene, 2-butene, isobutene, sulfur hexafluoride, helium, carbon monoxide, nitrogen monoxide, etc.    ADVANTAGE - Since boss portion of tubular separation membrane is penetrated by the penetration hole of one baffle and end block is penetrated by the penetration hole of other baffle, the separation performance of tubular separation membrane does not deteriorate even if boss portion and end block contact the internal peripheral surface of the penetration hole. The pressure loss becomes small by arranging a baffle only to a housing both end side. The zeolite film is not damaged, even if a tubular separation membrane vibrates and the tubular separation membrane contacts the internal peripheral surface of the penetration holes. Hence the multi-tubular-type separation-membrane module can be operated stably over a long term. A drift does not arise in the housing, and the to-be-processed fluid contacts the tubular separation membrane uniformly with permeable flow volume.
