Blending Experiment


Aims

The aims of this experiment are:


Theory

The theory describing how to obtain and analyse the RGA can be found in:

Module 6 - Multivariable Systems.


Experimental Apparatus and Procedure

The experimental setup for this simulation consists of:

There are two different ways of running the above system.

The experimental setup and procedure for each is discussed in turn below.


Constant Outflow

The first set of experiments deals with a constant outflow

The experimental apparatus therefore is shown below:

The aim of the experiment is to try and match up the measurements and manipulations using the RGA method discussed in the theory section. This will depend in part on the initial conditions in the tank and the operating conditions during the experiment. Therefore there are two different experiments.

Following the links below will take you to a further discussion about the experimental conditions along with pre-experimental questions to guide you through each simulation.



Constant Diluent Flow

The first set of experiments deals with a constant diluent flow.

The experimental apparatus again is shown. Note that this time there is only one way to run this experiment.

The first aim of this experiment is to evaluate the gain matrix and RGA and show that there is only one way to match up these variables (the flow out from the tank does not have any effect on the concentration in the tank). The second aim of the experiment is to run the two loops separately and then run them together to see how they interact and how the tuning is affected.

Following the link below will take you to a further discussion about the experimental conditions along with pre-experimental questions to guide you through the simulation.
