RDR-350 Rotating disk reactor

The RDR-350 conducts reaction rate experiments between fluids and rock surfaces. The effects of mass transfer and chemical reactions are determined by varying the rock sample rotational speed and reaction temperature. The apparatus consists of a disk of rock spinning in a volume of reactive fluid at a constant angular velocity. The concentrations of the reactants in the bulk are measured by atomic absorption spectrophotometry at various time intervals while the disk is rotating at a fixed speed. The global reaction rate at a given angular velocity is computed from the change in reactant concentration versus time. The experiment is then repeated at different angular velocities to obtain the reaction rate as a function of angular velocity. Additional experiments at different temperatures or different test fluid concentrations can be performed to obtain the full rate law for the reaction system.
