Chemical Reaction Engineering
For a tubular reactor with space time 'τ' and residence time 'θ', the following statement holds good.

τ = θ , for an isothermic tubular reactor in which the density of the process fluid is constant

τ and θ are always equal

τ = θ , when the fluid density changes in the reactor

τ = θ , for a non-isothermal reactor

τ = θ , for an isothermic tubular reactor in which the density of the process fluid is constant

τ and θ are always equal
