How do you design a reactor?

General Reactor Design

1. Step 1: Collect Required Data.
2. Step 2: Select Reaction Conditions.
3. Step 3: Determine Materials of Construction.
4. Step 4: Determine Rate-Limiting Step and Critical Sizing Parameters.
5. Step 5: Preliminary Sizing, Layout, and Costing of Reactor.
6. Step 6: Estimate Reactor Performance.

What is chemical reactor design?

In chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction, which is one of the classic unit operations in chemical process analysis. The design of a chemical reactor deals with multiple aspects of chemical engineering.

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.

How many types of chemical reactors are there?

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.

How do you size a reactor?

In order to size a reactor we must first know what the reactor should do, i.e. how large conversion (omsättning) it should accomplish. Fractional amount of reactant species (A) converted into product(s) or consumed by reaction. Indicates extent of reaction. Expressed in terms of limiting reactant.

How do you calculate volume of a reactor?

By definition, space velocity can be expressed mathematically as SV = Vo / V. In this expression, Vo represents the volumetric flow rate of the reactants entering the reactor and V represents the volume of the reactor itself.

What is the type of reactor?

The two main types of reactor are termed batch and continuous.

How do you size a vessel?

For systems with 82℃ / 71℃ flow and return and cold fill pressure up to 1.5 bar, a good rule of thumb is, 1 litre vessel capacity minimum per KW boiler output – round up to larger vessel capacity (e.g.160 KW boiler may require 200 litre vessel).
