Phase and reaction equilibria determine process feasibility.
Thermodynamics determines feasibility and equilibrium: Gibbs energy ΔG=ΔH-TΔS, ΔG°=-RT lnK, fugacity, activity coefficients, phase equilibria and equations of state (Peng-Robinson). Guides reactor conditions and separation design.
Higher temperature favours endothermic reactions.
Chemical thermodynamics tells you whether a reaction or separation is possible and how far it will go, which is essential before design.
Phase and reaction equilibria determine process feasibility.
Chemical thermodynamics tells you whether a reaction or separation is possible and how far it will go, which is essential before design.
Whether a process can occur spontaneously at constant temperature and pressure, with negative values favouring the reaction.
Equilibrium sets the maximum possible conversion at given conditions, so a process may need recycling to reach a high overall yield.
Typical applications include estimating the equilibrium conversion of an esterification reaction, checking whether a separation is possible at a given temperature and predicting the Gibbs energy change for a reaction at operating temperature.
Study "P&ID" first (topic 69 of 100 in Materials & Chemical). It covers the groundwork this topic builds on.
Equilibrium constant. Excess Gibbs energy models (NRTL, UNIFAC). Spontaneity.
Higher temperature favours endothermic reactions.
The next topic is "Vapour-liquid equilibrium", which builds directly on this one.
It is classed as Advanced in Materials & Chemical (topic 70 of 100). It is an advanced topic. It assumes you are comfortable with the intermediate topics in Materials & Chemical.
