Tóm tắt
This article deals with the experimental and theoretical localization of steady state maximum temperature along
an exothermic tubular reactor in counter current flow configuration; which represents a key parameter for safety in the
chemical engineering processes. The fluid flowing in the inner tube is a mixture of sodium thiosulfate solution in reaction
with hydrogen peroxide. To control the reactive fluid temperature, the inner tube is cooled with a refrigerant fluid flowing
through the annular space. The steady state is obtained from the resolution of the nonlinear partial differential equations
with the McCormack numerical method. The steady state temperature of the reactive fluid along the tubular reactor presents
a maximum value due to the exothermic chemical reaction. The maximum temperature value which represents the
critical point of the reactor is investigated. In particular its localization is studied for the first time according to various parameters
such as flow rates, reactant concentrations and inlet temperatures.
