What is the industrial application of PFR and CSTR?
The continuous-flow, well-stirred tank reactor or CSTR finds wide application in the chemical industry from pilot plant to full-scale production operation. The basic arrangement, sketched below, comprises a tank thermostated at some surrounding temperature Ta into which one or more reactant feed streams flow at some controlled rate. The contents react in the tank and are stirred either mechanically or as a consequence of the flow characteristics, and there is an outflow.The various control parameters include:· the inflow concentrations ci,0 of the different reactants;· the total volumetric flow rate v through the reactor;· the ambient temperature or the temperature of any cooling jacket Ta· the inflow temperature T0 (which may be different from Ta)whilst other features, such as reactor shape and size might be of interest at the design stage.The response variables are the concentrations ci and the temperature T within the reactor.The product/reactant mix flows out with concentrations ci and temperature T equal to the values in the reactor.The continuous inflow of fresh reactants (and matching volumetric outflow of reactant and-product mixture) provides a thermodynamically open system, in which true steady state behaviour can be sustained 'indefinitely'.by Baijnath

No
Does condensate return need to go through a flash tank prior to a DA tank for a steam boiler system?
In a steam boiler system, condensate return does not necessarily need to go through a flash tank before entering the Deaerator (DA) tank. However, using a flash tank can be beneficial in recovering some heat and reducing pressure, allowing for more efficient use of the condensate. This process can help minimize the amount of makeup water required and improve overall system efficiency. Ultimately, whether to include a flash tank depends on the specific system design and operational requirements.

The Feed conditons entering are at 25 deg c with 101.3 kpa the reactor is a cstr operating at 65deg c the product if ethylene glycol!!!!!!
Diffeerence between CSTR and PFR on volume baises?
For simple understanding PFR can be imagined as multiple CSTR's in series. PFR has benefits of higher conversion rates, product uniformity & less energy losses. CSTR stands for Continuously Stirred Tank Reactor. PFR stands for Plug Flow Reactor.
What is the calculation of residence time distribution for ideal continuous stirred tank reactor?
dividing output wolume with reactor volume
How do you do an energy balance for a cs-tr?
To perform an energy balance for a CSTR (continuous stirred-tank reactor), you need to account for the energy input (heat, work) and output (cooling, agitation losses, heat exchange with surroundings) in the system. The energy balance equation typically involves the heat generated or consumed in the reaction, the heat capacity of the reactor contents, and the temperature changes within the reactor. By summing up these energy terms, you can determine the overall energy balance for the CSTR system.

Is a PFR better than a CSTR?
Whether a Plug Flow Reactor (PFR) is better than a Continuous Stirred Tank Reactor (CSTR) depends on the specific application and reaction kinetics. PFRs typically offer higher conversion rates for first-order reactions due to their flow characteristics, allowing for better control of residence time and concentration gradients. However, CSTRs provide more uniform conditions and are easier to mix, making them suitable for reactions that require thorough mixing or have complex kinetics. Ultimately, the choice between the two depends on factors such as reaction type, desired product yield, and operational constraints.

What are the advantages of stirred tank bio reactors over shake flasks?
Stirred tank bioreactors provide better control over environmental conditions such as temperature, pH, and oxygen levels compared to shake flasks. They also allow for continuous monitoring and sampling of the culture without the need to disrupt it. Additionally, stirred tanks have larger volumes, enabling production of larger quantities of biomass or products.
Whats better for an exothermic reaction a PFR or CFSTR reactor?
That depends on what kind of reaction system you have. Generally, large CSTRs are not suited for use at high pressures because of mechanical strength limitations. Typically, they are used for liquid phase reaction systems at low or medium pressures when appreciable residence times are required. PFRs are more suitable at higher pressures and temperatures. The PFR are usally employed for liquid phase reactions when relatively short residence times are needed. It is the reactor of choice for continuous gas phase operations. Hope that helps.
