What are the factors to be considered for reactor design?
The different factors required for reactor design are (i) Size of reactor (ii) Type of reactor (iii) Time or duration of reaction (iv) Temperature & Composition of reacting material in the reactor (v) Heat removal or added and (vi) Flow pattern of fluid in the reactor.
What is chemical reactor design?
A chemical reactor is an enclosed volume in which a chemical reaction takes place. The design of a chemical reactor deals with multiple aspects of chemical engineering. Chemical engineers design reactors to maximize net present value for the given reaction.
How do you design a reactor?
General Reactor Design
- Step 1: Collect Required Data.
- Step 2: Select Reaction Conditions.
- Step 3: Determine Materials of Construction.
- Step 4: Determine Rate-Limiting Step and Critical Sizing Parameters.
- Step 5: Preliminary Sizing, Layout, and Costing of Reactor.
- Step 6: Estimate Reactor Performance.
What are the types of reactors?
Main types of nuclear reactor
- Pressurised water reactor (PWR)
- Boiling water reactor (BWR)
- Advanced gas-cooled reactor (AGR)
- Light water graphite-moderated reactor (LWGR)
- Fast neutron reactor (FNR)
- Nuclear power plants in commercial operation or operable.
How does a tubular reactor work?
The tubular reactors work on the principle of continuous flowing systems in a cylindrical geometry. First you will introduce a fluid or fluids that you intend to mix with other reactants into the tubular reactor. As the fluids of reactants flow through the tube or tank, there is a chemical reaction that takes place.
What is the function of reactor?
The main job of a reactor is to house and control nuclear fission—a process where atoms split and release energy. Fission and Fusion: What is the Difference? Reactors use uranium for nuclear fuel. The uranium is processed into small ceramic pellets and stacked together into sealed metal tubes called fuel rods.
Why are chemical reactors important?
INTRODUCTION. The most important unit operation in a chemical process is generally a chemical reactor. Chemical reactions are either exothermic (release energy) or endothermic (require energy input) and therefore require that energy either be removed or added to the reactor for a constant temperature to be maintained.
What is kinetics and reactor design?
Chemical kinetics is the study of rate and mechanism by which one chemical species is converted to another. Thermodynamics is an engineering fundamental having various applications for the chemical reactor design.
What is design equation?
Equation which, based on production measurements or specifications, provides a performance property useful in design calculations. NOTE A design equation can be defined by applying reasonable extremes to the variables in a limit state equation to arrive at a conservative value of expected performance.
What are the two main types of reactors?
There are two basic types: the pressurized-water reactor (PWR) and the boiling-water reactor (BWR).
What are the types of chemical reactors?
The three classical generic chemical reactors are the batch reactor, the continuous stirred-tank reactor (CSTR), and the plug flow tubular reactor (PFR). Each of these reactor types has its own unique characteristics, advantages, and disadvantages.
What is reactor design and why is it important?
Reactor design uses information, knowledge, and experience from a variety of areas-thermodynamics, chemical kinetics, fluid mechanics, heat transfer, mass transfer, and economics. Chemical reaction engineering is the synthesis of all these factors with the aim of properly designing a chemical reactor.
What process input data is required for reactor design?
Out of all process equipment, reactor design requires the most process input data: reaction enthalpies, phase-equilibrium constants, heat and mass transfer coefficients, as well as reaction rate constants.
What is chemical reaction engineering?
Chemical reaction engineering is the synthesis of all these factors with the aim of properly designing a chemical reactor. To find what a reactor is able to do we need to know the kinetics, the contacting pattern and the performance equation. We show this schematically in Figure (1).
What are the different types of chemical reactors?
Identifying type of chemical reactor. Batch/plug flow/Mixed flow. All chemical reactors come under these 3 categories. Identifying the type of system. Either homogeneous or heterogeneous system. Finding the order of reaction, rate equation of chemical reaction and rate constants. They mainly depend on the type of system.
