Gas separation membrane module

A membrane module for gas separation, comprising:

• a housing;
• a gas separation membrane disposed in the housing;
• and
• an adhesive part for affixing the gas separation membrane to the housing, wherein
• the gas separation membrane is composed of a porous membrane,
• the adhesive part satisfies at least one of the following (1) to (6):
• 1) the adhesive part has a low-mobility component having a composition ratio V (%), as measured by pulse NMR, wherein 30≤V≤100;
• 2) the adhesive part has an attenuation rate W (%) represented by the following formula:
• W=[(I1−I2)/I1]×100
• wherein I1 is a signal intensity at start of measurement in the pulse NMR of the adhesive part, I2 is a signal intensity 0.05 msec after the measurement starts, and
• wherein 30≤W≤100;
• 3) the adhesive part has a change ratio X (%) represented by the following formula:
• X=[(V2−V1)/V1]×100
• wherein V1 and V2 respectively represent the composition rates V(V1(%)) and V(V2(%)) before and after immersion of the adhesive part in a 7 mol/L aqueous silver nitrate solution or heptane for 1 month at 25° C., and
• wherein −50≤X≤50;
• 4) the adhesive part has a change ratio Y (%) represented by the following formula:
• Y=[(W2−W1)W1]×100
• wherein W1 and W2 respectively represent the attenuation rates W(W1(%)) and W(W2(%)) before and after immersion of the adhesive part in a 7 mol/L aqueous silver nitrate solution or heptane for 1 month at 25° C., respectively, and
• wherein −120≤Y≤120;
• 5) the adhesive part has a nitrogen atom content (CN, % by mass), wherein 0.0010≤CN≤10, and a sulfur atom content (CS, % by mass), wherein 0.0010≤CS≤0.01;
• and
• 6) the adhesive part has a hardness K, wherein 10D≤K≤90D.
