Stability criteria and critical runway conditions of propylene glycol manufacture in a continuous stirred tank reactor

Here, a new method for the analysis of the steady state and the safety operational conditions of the hydrolysis of propylene oxide with excess of water, in a Continuous Stirred Tank Reactor (CSTR), was developed. For industrial operational typical values, at first, the generated and removed heat bal...

Inicialmente, para valores típicos de operación industrial, se examinaron los balances de calor generado y removido. Luego, se analizó el efecto de la temperatura del fluido de enfriamiento en las temperaturas de ignición y extinción (TCI y TCE, respectivamente). También se estudió el efecto del parámetro de transferencia de calor (hS) sobre las temperaturas críticas y del fluido de enfriamiento. Finalmente, se definieron las áreas de operación estables. Se reconoció la existencia de múltiples estados estables cuando el parámetro de transferencia de calor está en el intervalo de 6.636 hS kJ/(min.K) 11.125. El área de operación inestable está localizada entre los valores de TCI y TCE, restringiendo la operación del reactor al área de bajas temperaturas estables.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ingenieríahttps://revistas.unal.edu.co/index.php/ingeinv/article/view/46258Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónGómez, Miguel Ángel and López Zamora, Sandra Milena and Gómez, Isabel Dobrosz (2015) Stability criteria and critical runway conditions of propylene glycol manufacture in a continuous stirred tank reactor.
