What is a stirred pressure reactor, and how does it differ from other types of reactors?

A Stirred Pressure Reactor (SPR) is a type of reaction vessel used in chemical processes that operates under pressure while being continuously stirred. The stirring mechanism ensures uniform mixing of reactants, heat transfer, and efficient contact between phases. Unlike batch reactors, which operate in a single cycle, or plug flow reactors, which rely on unidirectional flow, a Stirred Pressure Reactor combines both high pressure and agitation. This results in better control over reaction conditions, making it ideal for reactions that require precise temperature and pressure management.
