    摘要: A gas separation module comprising: (a) a permeate collection tube; (b) a membrane envelope wound spirally around the tube to provide a wound membrane structure comprising two end faces; and (c) an anti-telescoping device (ATD) secured to the permeate collection tube, the ATD comprising: (i) an inner peripheral part, (ii) an outer peripheral part which surrounds the inner peripheral part, (iii) one or more connection parts which connect the inner peripheral part and the outer peripheral part and which contacts with one of said end faces; (iv) vents which allow gas to flow through the ATD; wherein the ATD satisfies Formula (1): (L CP−L contact)/(L VENT)=R Formula (1) wherein: R is from 1.47 to 1.88; L VENT is the cross sectional area of the vents which allow gas to flow through the ATD; L CP is the total area inside the outer peripheral part; and L contact is the contact area of the connection parts and the end face of the wound membrane envelope. Clamps are also claimed.
