Opportunity crudes and refinery challenges during hydrocracking operations—Part 2
Refineries worldwide often face practical challenges and operating issues when processing opportunity crude oils to maximize profit margins.
A dynamic 1D model for accelerated reactor cooling
Refinery hydrofining units must undergo planned and emergency shutdowns for catalyst changeover.
Accurate prediction of phase equilibrium properties—Part 1
Phase equilibrium properties, such as bubble-point, hydrocarbon dewpoint, water dewpoint, phase envelope, two-phase compositions, compressibility factor, hydrate equilibrium properties, etc., for hydrocarbon mixtures have been calculated accurately using the Peng-Robinson cubic equation of state by implementing constant and temperature-dependent binary interaction parameters in the Van der Waals mixing rule.
