Which temperature are used in PFR reactor?

It reaches temperatures of 800 – 1100°C.

How do you calculate the energy balance of a reactor?

1. The energy balance for the constant-pressure case follows from Equation 6.15. CP.
2. dT. dt= −∆HRknA.
3. in which CP = VRρ ˆ
4. CP is the total constant-pressure heat capacity. For an ideal gas, we. know from thermodynamics that the two total heat capacities are simply related,
5. CV = CP − nR. (6.21)

What is the material balance equation for plug flow reactor?

A material balance on the differential volume of a fluid element, or plug, on species i of axial length dx between x and x + dx gives: [accumulation] = [in] – [out] + [generation] – [consumption] where: x is the reactor tube axial position, m.

How is heat duty of a reactor calculated?

i.e. condenses.

1. Heat Duty (Sensible heat – No phase change) Q = M * Cp * ∆T. Where;
2. Heat Duty (Latent heat – Phase change) Q = M * λ Where;
3. Heat Duty for Multiphase streams. If you have a stream where more than one phase exists then you can calculate the heat duty using the equation below: Q = Qg + Qo + Qw.

What is plug flow in viscometer?

In fluid mechanics, plug flow is a simple model of the velocity profile of a fluid flowing in a pipe. In plug flow, the velocity of the fluid is assumed to be constant across any cross-section of the pipe perpendicular to the axis of the pipe.

What is reactor volume?

Reactor volumes per day (RVD) control is probably the most simplistic method by which a perfusion process can be developed and operated. Typically, a flow rate is set per day and increased as the cell concentration increases. The general rule is if the growth rate slows, then the RVD is increased.

How do I choose between PFR and CSTR?

Rate of reaction is directly proportional to reactant concentration for positive order reactions. More the concentration more will be the rate. Hence PFR gives higher conversion than CSTR for positive order reactions.
