What is space time in reactor?
Space time is the time necessary to process one volume of reactor fluid at the entrance conditions. This is the time it takes for the amount of fluid that takes up the entire volume of the reactor to either completely enter or completely exit the reactor. Sample Industrial Space Times. Reaction.

When would you use a plug flow reactor?
Plug flow reactors are used for some of the following applications:
- Large-scale production.
- Fast reactions.
- Homogeneous or heterogeneous reactions.
- Continuous production.
- High-temperature reactions.
How do you calculate volume of a reactor?
By definition, space velocity can be expressed mathematically as SV = Vo / V. In this expression, Vo represents the volumetric flow rate of the reactants entering the reactor and V represents the volume of the reactor itself.
What are some characteristics of the CSTR reactor?
| Type of Reactor | Characteristics |
|---|---|
| Continuously Stirred Tank Reactor (CSTR) | Run at steady state with continuous flow of reactants and products; the feed assumes a uniform composition throughout the reactor, exit stream has the same composition as in the tank |
Is CSTR a batch reactor?
A continuous stirred tank reactor (CSTR) is a batch reactor equipped with an impeller or other mixing device to provide efficient mixing. In chemical engineering the name CSTR is often used to refer to an idealised agitated tank reactor used to model operation variables required to attain a specified output.
What is the meaning of the space velocity 5 per hours?
A space velocity of 5 hr⁻¹ means that A. Five reactor volumes of feed (at specified conditions) are being fed into the reactor per hour. After every 5 hours, reactor is being filled with the feed. Cent per cent conversion can be achieved in at least 5 hours. A fixed conversion of a given batch of feed takes 5 hours.
What is the significance of space-time and space velocity?
Explanation: Space time is the time spent by a unit volume of reactants inside the reactor. It is the performance measure for a flow reactor. Explanation: Space velocity has the dimensions of time-1. A space velocity of 2 hr-1 implies that 2 reactor volumes are fed per hour.
What is the conversion equation?
Conversion Rate = Total number of conversions / Total number of unique visitors * 100. Conversion Rate = Total number of conversions / Total number of leads * 100.
What does conversion mean in chemistry?
Conversion is defined only for the Reactants not for products, For reactant A Conversion is defined as the Number of moles of A reacted to the Total number of moles of A fed into the system(i.e. Reactor). It is a basic term in a Chemical kinetics and plays a vital role in the Chemical Reaction Engineering.
