What is PFR and CSTR?
What is PFR and CSTR?
(CSTR and PFR stand for Continuous Stirred-Tank Reactor and Plug Flow Reactor.) For zero-order kinetics, this ratio is always equal to one and is independent of conversion.
How many types of reactors are there?
There are two basic types: the pressurized-water reactor (PWR) and the boiling-water reactor (BWR).
What is reactor in pharma?
Reactor is a process vessel in which raw materials are added and reaction can be conducted. There are different type of reactors use in different type of industries like pharmaceutical industries, color and dyes industries, petro chemical industries, fine chemical industries and many more.
Which reactor is used in pharmaceutical industry?
The batch reactor is used in the pharmaceutical industry for the production of drugs, where a rapid and precise temperature control is necessary. The model has to be built to include all the main features necessary for the purposes of modelling.
Which one is better CSTR or 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.
Is PFR better than CSTR?
At high fractional conversion values, the volume required for a CSTR increases rapidly compared the the volume of a PFR. If reactor volume is the only criterion for deciding the type of reactor to use, clearly PFRs are the optimal choice.
What is MOC in reactor?
Apart from the types of reactor, reactors are classified based on the material of construction. MOC means the material of which the equipment is made up. Reactors of different materials such as Stainless steel and glass-lined reactor.
Which nuclear reactor is best?
Top ten nuclear power plants by capacity
- Gravelines Nuclear Power Plant, France.
- Paluel Nuclear Power Plant, France.
- Cattenom Nuclear Power Plant, France.
- Yangjiang Nuclear Power Plant, China.
- Shin Kori Nuclear Power Plant, South Korea.
- Hongyanhe Nuclear Power Plant, China.
- Fukushima Daini Nuclear Power Plant, Japan.
What is PWR and BWR?
The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to steam and then drives a steam turbine. In a PWR, the reactor core heats water, which does not boil.
What is SSR reactor?
Jacketed Reaction Stainless Steel Reactor Vessel for cooling / heating. Reaction vessel is a container with an agitator for mixing, dispersing and reaction of different materials in chemical production. It is widely used in chemical, food, pharmaceuticals, resin, coating, paint, printing ink industry.
Why we use CSTR instead of PFR?
To achieve the desired conversion with smaller reactor volumes, use a combination. In this case, use a CSTR then a PFR. By doing so, the reactor volume is less than the area underneath the curve.
Why does PFR have better conversion than CSTR?
How do I choose between CSTR and PFR?
To achieve the desired conversion with smaller reactor volumes, use a combination. In this case, use a CSTR then a PFR. By doing so, the reactor volume is less than the area underneath the curve. For competing parallel reactions, selectivity for desired product can dominate the choice.
What is GLR and SSR?
Glass Lined Reactors (GLR) Alkaline. >7. Stainless Steel Reactors (SSR)
Why glass lined reactor color is blue?
The blue coloring comes from the cobalt that was added to the glass formulations a long time ago. Usually the choice of which color to use comes down to concerns about cleaning and what particles could be left behind.
