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.... Platforms: Matlab

We would like to rise water temperature with a heater. Oulet temperature must be equal to the set point temperature (80dlT-C). Proportional (P), Proportional-Integral (PI) and Proportional-Integral-Derivative (PID) control are used and the respective results are compared. Inlet water temperature... Platforms: Matlab

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... Platforms: Matlab

The two programs computes residue curve maps for the methyl acetate and isopropyl acetate chemistries at atmospheric pressure. These calculations involve solving a complex system of differential algebraic equations (DAEs). This can be readily achieved using the built-in function of MatLab,... Platforms: Matlab
