A space time of 3 hours for a flow reactor means that___________________?
Correct answer: A. The time required to process one reactor volume of feed (measured at specified conditions) is
- A. The time required to process one reactor volume of feed (measured at specified conditions) is
- B. 3 hours
- C. Three reactor volumes of feed can be processed every hour
- D. It takes three hours to dump the entire volume of the reactor with feed
- E. Conversion is cent per cent after three hours
Explanation
Space time is the reactor volume divided by the volumetric feed rate, so it represents the time needed to process one reactor volume of feed at the specified conditions. It is not necessarily the actual residence time for every fluid element.

A CSTR is to be designed in which an exothermic liquid phase first order reaction of the type, A → R, is taking place. The reactor is to be provided with a jacket in which coolant is flowing. Following data is given: CA0= 5 kmole/m3; XA = 0.5; Feed temperature = reactor temperature = 40°C. Rate constant at 40°C = 1 min-1; (ΔH) = - 40kJ/mole; ρ = 1000kg/m3 CP = 4 J/gm.°C ; q = 10-3 m3/min (ρ and CP are same for the reactant and product streams). The amount of heat to be removed is_________________?
