Chemical Reaction Engineering Batch process is preferred over continuous process, when the Same equipment can not be used for several processes of the same nature Product yields and quality can not be achieved in continuous process, because of long residence time Sales demand of product is not steady All of these Same equipment can not be used for several processes of the same nature Product yields and quality can not be achieved in continuous process, because of long residence time Sales demand of product is not steady All of these ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering 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 2/3 kW 4kW 1kW 5/3 kW 2/3 kW 4kW 1kW 5/3 kW ANSWER DOWNLOAD EXAMIANS APP
