Combining Equations 24.5 and 24.6, we arrive at the design equation for CSTRs: [j]0 − [j] = − τrj Note that if [j]0 − [j] > 0, then j is depleted in the reaction, and this means that rj < 0, as we would expect if, for example, j is a reactant.

Continuous Stirred Tank Reactor. CSTR DESIGN EQUATIONS Space Time and Space Velocity concept The space time, τ , is the time required to process one reactor volume of feed and is given by the following equation: Ao Ao o C V V Fv eq 5-36 where C Ao is the initial concentration Approach to steady state in a continuous stirred tank reactor (CSTR).
