Gas absorption is a very ubiquitous unit operation in any chemical plant. It has in common with liquid-liquid extraction that there are two carrier streams and one solute to be partioned between them. Here, we use the McCabe and Thiele graphical method to study the separation of acetone from air....

We would like to rise water temperature with a heater. Oulet temperature must be equal to the set point temperature (80dlT-C). Proportional-Integral-Derivative (PID) control is used. Inlet water temperature is equal to 20dlT-C. Water flow is equal to 10 m3/hr. Tank volume is equal to 100 m3....

MolMass is a function for calculating the molar weight of a substance given in form of a chemical formula.Function call: MM = MolMass(substance)Substance is a string of the chemical formula of a substance.Example: MM = MolMass('Fe2(SO4)3');Substance can also be a vector of substances opened by...

It is desired for modern process systems to achieve optimal operation. However, operation at a pre-designed nominally optimal point may not necessarily be actually optimal due to realtime disturbances, measurement and control errors and uncertainties. Self-optimizing control aims to tackle this...

PID control over the exit raffinate composition (x5) of a five stages column is obtained by changing solvent flow rate (G). The set point is equal to 0.1. The model equations include backmixing effects. This problem is solved using Berkeley-Madonna in Chemical Engineering Dynamics, Ingham et al.,...

A reaction object contains parameters that describe a chemical reaction scheme in terms of reagents, reaction steps, rate constants and equilibrium constants. The reaction can be evaluated to provide concentrations of species as a function of time and starting concentration. The reaction can also...
