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
What are different types of fermentor?
1. Stirred tank fermentor 2. Airlift fermentor 3. Toerw fermentor 4. Bubble-up fermentor
Fluidized media reactor?
It is a single tank unit, consisting of a bar screen chamber, specially designed floating media to facilitate the attached growth process, oxygen transfer through diffused membrane aeration, lamella settler and chlorine contact tank. The system is available in mild steel and reinforced concrete. These systems are using for "WASTE WATER TREATMENT". Mahipal Reddy M Ionexchange Services lmtd Ph- +91 9986953011
Can you use cng in a lpg tank?
No
How can be maintain the mlss in aeration tank?
by drain the sludge of secondary tank from time to time....and one may also maintain mlss by the addition of jaggery ...

What are the conditions for reaction between Ethylene oxide and water in a plug flow reactor or in a Continuous Stirred Tank Reactor?
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 equation for reaction rate?
. The transformation of glucose into fructose by the enzyme glucose isomerase, was carried out in two different types suspended-enzyme bioreactors: 1) CSTR, and 2) plug flow reactor. The process obeys Michaelis-Menten kinetics. The following parameters and kinetic constants were kept the same in both bioreactors: $ So (input substrate concentration) = 1.0 mMol/L; $ F (volumetric flow rate) = 1.0 m3/h; $ Km = 7x10-4 Mol/L; $ Vmax = 0.2 mMol/(L.h) Determine: $ Volume of CSTR for 50% conversion of glucose; $ Volume of PFR for 50% conversion of glucose; $ Volumes of CSTR and PFR in series (assume that the volumes are equal) in two cases: $ first CSTR $ first PFR 2. Calculate the volume of a stirred tank bioreactor containing the same enzyme, but immobilized on the surface of a flat-geometry support. The value of the mass-transfer coefficient is 0.6 h-1. The values of the rest of process parameters are the same as above.
