1. A shell-and-tube heat exchange reactor comprising:
a plurality of elongated tubes in which an inlet end of each of the elongated tubes is affixed to an inlet tube sheet and the outlet end of each of the elongated tubes is affixed to an outlet tube sheet; and
at least one baffle positioned between the inlet tube sheet and the outlet tube sheet and configured to support each of the elongated tubes, wherein the at least one baffle comprises a plurality of corrugated stainless steel strips configured to form a grid pattern having tube openings, wherein each tube opening is spaced apart from an adjacent tube opening by a portion of one of the corrugated stainless steel strips and each tube opening permits one of the elongated tubes to pass there through, wherein the reactor is used in ethylene oxide (EO) production and each elongated tube is filled with a silver-based epoxidation catalyst.
