Parametric sensitivity of a CSTR

Parametric sensitivity of pH and steady state multiplicity in a continuous stirred tank bioreactor (CSTBR) using a lactic acid bacterium (LAB),Pediococcus acidilactici

“…Pediococcus acidilactici , is also parametrically sensitive irrespective of the occurrence of a multiplicity of steady state. As observed by Chemburkar et al , during studies on an exothermic adiabatic CSTR, multiplicity occurs simultaneously with parametric sensitivity. Besides the existence of strong parametric sensitivity in the region of multiplicity, it is also present moderately with respect to D and D 1 and strongly with respect to s b in the region of unique steady state.…”

“…15,16,23 However, effort should also be made to investigate the parametric sensitivity of pH in CSTBRs. During studies on nth order irreversible exothermic reactions in a non-adiabatic CSTR, Chemburkar et al 24 showed that there exists a distinct relationship between parametric sensitivity of temperature and multiplicity of steady states. However, no such article dealing simultaneously with both parametric sensitivity of pH and multiplicity of steady states in CSTBRs is currently available.…”

Modeling the effect of wall capacitance on the dynamics of an exothermic reaction system in a batch reactor

“…The technique of early detection by hazardous states in chemical reactors has been developed by Gilles and Schuler [13] who predicted a safe operation detection system by applying one order and second order differentiation of reaction temperature with time. Hugo et al [14] concluded that as far as safe operation problem in reaction is concerned, reactors should [15] proposed the generalized parametric criterion to determine the safe operation in a continuous stirred tank reactor while Morbidelli and Varma [6] applied the same method to determine the safe operating region for batch reactor operation.…”

Thermal Stability of Gas Oil Hydrotreating Processes: Numerical Issues of the Matrix-Eigenvalue Approach

“…This situation can lead to thermal runaway [3]. This concept has been widely applied for chemical reactors thermal stability analysis [4][5][6][7][8][9][10][11][12][13][14]. Both approaches, performed under stationary conditions, help to define stability/instability maps as a function of the most important parameters such as operating conditions and model parameters.…”
