gPROMS Advanced Model Library for Gas-Liquid Contactors (AML:GLC) is an “open-model” library of high-fidelity, non-equilibrium component models for gas-liquid separation. It is designed to cover a wide range of separation operations, including conventional packed columns for distillation, absorption and evaporation, and more complex units such as heat-integrated devices, partition columns, partial condensers, compact heat and mass exchangers (dephlegmators), and falling-film columns. The approach used in the AML:GLC results in accurate information for decision support in optimization of process, equipment and control design and operations. Accuracy is achieved by using a rate-based approach that employs dual-flow hydrodynamics for estimation of heat and mass transfer, making the assumption of equilibrium only at the infinitesimally thin interface between gas and liquid films. Non-condensibles are handled rigorously in both phases.
