Sizing of reactors by charts of Damkohler's number for solutions of dimensionless design equations.

ABSTRACT: The reaction kinetic rate and mass transport play an important role in the sizing and scale-up of reactors. The Damköhler's dimensionless number ( Da ) is the quotient of these effects. A new interpretation of Da as a local property is introduced Da(x,y,z,t) . A new graphical methodology is proposed for the sizing and scale-up of unidirectional flow reactors and CSTRs. The partial differential equation (PDE) and algebraic that describe the continuity within these reactors transform into dimensionless variables, and the conversion at the output is expressed as a function of the conditions at the input Da0 . The operating conditions as volumetric flow, residence time; design variables as reactor volume; and intrinsic reaction rate are involved in Da0 . The equations are solved numerically to
