Where is CSTR used?
Continuous stirred-tank reactors are most commonly used in industrial processing, primarily in homogeneous liquid-phase flow reactions, where constant agitation is required.
They may be used by themselves, in series, or in a battery.
CSTRs are also used in the pharmaceutical industry as a loop reactor..
How do I choose between CSTR and PFR?
For between PFRs and CSTRs: With positive order kinetics (ie. reaction rate increases with increasing starting material concentrations) you will always get higher conversion with a PFR. You would choose a CSTR if the reaction was autocatalytic and you didn’t want to reflux a PFR.
What is PFR and PR?
Plants grow toward sunlight because the red light from the sun converts the chromoprotein into the active form (Pfr), which triggers plant growth; plants in shade slow growth because the inactive form (Pr) is produced. If seeds sense light using the phytochrome system, they will germinate.
Which is active PR or PFR?
Pfr is the physiologically-active form of the protein; exposure to red light yields physiological activity in the plant. Exposure to far-red light converts the Pfr to the inactive Pr form, inhibiting phytochrome activity. Together, the two forms represent the phytochrome system.
How is PR converted to PFR?
Pr absorbs red light (~667 nm) and is immediately converted to Pfr. Pfr absorbs far-red light (~730 nm) and is quickly converted back to Pr. Absorption of red or far-red light causes a massive change to the shape of the chromophore, altering the conformation and activity of the phytochrome protein to which it is bound.

What does SSF mean in medical terms?
Sacrospinous fixation (hysteropexy) surgery helps restore support to the uterus or vaginal vault in the case of a previous hysterectomy (uterus removal).
What does MW stand for in medical terms?
molecular weightAbbreviation for molecular weight.
What is the difference between CSTR and PFR?
A PFR has a higher theoretical efficiency than a CSTR of the same volume. That is, given the same space-time (or residence time), a reaction will proceed to a higher percentage completion in a PFR than in a CSTR. This is not always true for reversible reactions.
How does PFR work?
The PFR model is used to predict the behaviour of chemical reactors of tubular design, so that key reactor variables, such as the dimensions of the reactor, can be estimated. … As the plug flows down the PFR, the residence time of the plug element is derived from its position in the reactor.
What is the meaning of CSTR?
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.
