Manufacture of Ammonia From Natural Gas: Source: Ed Cussler

This document discusses the design of chemical reactors for viable chemical reactions under specified process conditions. It outlines the module objectives of explaining chemical kinetics concepts, analyzing rate measurements, designing and optimizing chemical reactors, and understanding interactions between transport processes and reaction kinetics. It also lists the key activities in chemical reactor design, such as selecting thermodynamically feasible reactions and processing conditions, specifying the design basis, selecting the reactor operation mode, collecting kinetics information, applying reactor design equations to determine reactor type and size, and designing the reactor geometry to avoid flow issues.
