The hermodynamic Stability Problem, from a Mathematical Optimisation Perspective

Flash calculations are used for the dynamic simulation of vapor-liquid phase equilibria (VLE) in many chemical processes. When used to predict the composition of mixtures in VLE, the repeated applicatino of these flash calculations, particularly in dynamic cases can cause small inaccuracies to cascade. One way to prevent this, is to have strong...

High Pressure Hydrogen Dehydration Using Ionic Liquids

Renewable energy projects, such as wind and solar (PV) parks, are rapidly being built to replace fossil fuel based energy sources. The major drawback of electricity production from renewable sources is that they are intermittent and therefore lead to amismatch between the supply and the demand of energy. Energy storage in the form of hydrogen...

Solving Vapor-Liquid Flash Problems Using Artificial Neural Networks

Vapor-liquid phase equilibrium (flash) calculations largely contribute to the total computation time of many process simulation models. As a result, process simulations, especially dynamic cases, are limited in the amount of detail that can be included due to time restrictions. In addition, under certain conditions flash calculations can fail to...
