Abstract: A baffle (i.e., tube support) for use in a shell-and-tube heat exchange reactor, such as, for example, an ethylene oxide (EO) reactor, is provided that accommodates reduced tube pitch, and thus more catalyst packed tubes can be inside the reactor. The baffle, which can be referred to herein as a corrugated grid support, includes a plurality of corrugated stainless steel strips which sit into each other and form a grid pattern having tube openings. Each tube opening is configured to permit a catalyst packed tube to be inserted therein, while allowing a sufficient open area along the shell side of the tube to permit coolant to flow through the reactor.
