For a tubular reactor with space time 'η' and residence time 'ζ', the following statement holds good ?
Correct answer: A. η = θ, for an isothermic tubular reactor in which the density of the process fluid is constant
- A. η = θ, for an isothermic tubular reactor in which the density of the process fluid is constant
- B. η = θ, when the fluid density changes in the reactor
- C. η and θ are always equal
- D. η = θ, for a non-isothermal reactor
Explanation
Space time equals residence time when the fluid density, and hence volumetric flow rate, remains constant through the reactor. This condition is represented by an isothermal tubular reactor with constant process-fluid density.
