What is this for?
Context
Esterification reactions are very important in the process industry, generally esters are used in the chemical industry and in the food industry, these reactions are characterized by a reaction model.
Objective
Use the ethyl acetate reaction as an example to verify that the reaction model represents the reaction model in Logix.
How to use
Assumed items:
Limitations
In the current configuration, the chosen reactor is an ideal perfect mixture reactor (ideal CSTR) so that in the liquid inside, it is assumed that:
- There are no gradients in any of its properties and, therefore, the conditions of the output streams are the same as those of the fluid within it, this to simplify the implementation of the configuration.
- In the reactor there is no evaporation of any of the components and, additionally, the adiabatic process is considered.
- Mixture properties are not considered, that is, the properties of the mixture will be the weighted sum of the properties of each of the species.
- The properties of substances are all independent of composition and, therefore, invariant over time.
- Although the reaction is reversible, the reverse reaction can be considered negligible.
Problem to be addressed
The idea is to have an initial configuration element, to be able to start the configuration of a reaction model.
Is this useful for me?
The reaction model is useful because it could be used for other developers to represent Fischer–Speier esterification reaction model, between carboxylic acid and alcohol.

Installation Guide
To implement, check the steps below.
Step 1
Open FactoryTalk Logix Echo, add a new controller (ControlLogix5580) and connect it.
Step 2
Download the configuration .ACD in your laptop and run it in Studio 5000, observe reactants and products:
Step 3
After the reaction starts, the formation of products such as ethyl acetate uses the interaction between reactor volume, activation energy, ethanol and acetic acid compositions and follows this mathematical model.
Step 4
After the reaction starts, the formation of products such as water uses the interaction between reactor volume, activation energy, compositions of ethanol and acetic acid and follows this mathematical model.
