- Stability criteria and critical runway conditions of propylene glycol manufacture in a continuous stirred tank reactor S. M. López-Zamora I. Dobrosz-Gómez M. Á. Gómez-García Ingeniería propylene oxide propylene glycol Stability criteria runaway conditions The present paper presents the development of a new method for the analysis of the steady state and the safety operational conditions of the propylene oxide hydrolysis with excess of water in a Continuous Stirred Tank Reactor (CSTR). At first, for the industrial opera - tional typical values, the generated and removed heat balances were examined. Next, the effect of coolant fluid temperature on the critical ignition and extinction temperatures (T CI and T CE , respectively) was analyzed. The influence of the heat exchange parameter ( hS ) on coolant and critical temperatures was also studied. Finally, the steady state operation areas were defined. The existence of multiple stable states was recognized when the heat exchange parameter was in the range of 6.636 < hS kJ/(min.K) < 11.125. The Un - stable operation area was located between the T CI and T CE values, restricting the reactor operation area to the low stable temperatures. 2015 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64340413009 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.2 Vol.35
