gCrystal Software Suite
The gCrystal software suite’s easy-to-use, drag-and-drop graphical environment permits model-based innovation, engineering, and optimization of solution-crystallization processes, including precipitation. The program enables the creation of detailed models containing first-principles representations of the complex physics and chemistry of crystallization. The results can be used to develop high-fidelity predictive models, which can help to optimize crystallization process design and operation, determine optimal process economics, and manage risks associated with engineering decisions for both batch and continuous processes. These new model-based techniques enhance scaleup efforts to improve throughput and size consistency, often accompanied by energy savings. The program is suitable for use in pharmaceutical, food, chemicals, and mineral processing applications.

gPROMS Version 3.3
Version 3.3 of the gPROMS advanced process modeling (APM) software provides high-fidelity predictive process modeling for process engineers. The latest version contains improved productivity features that help the user to quickly obtain initial solutions for complex processes such as coupled reactions and distillation flowsheets. Special features help facilities to protect the intellectual property embodied in their models so that they may be distributed securely within and outside the organization. When used to carry out high-fidelity predictive modeling of both products and processes, the APM program can help engineers to speed innovation, manage development risk, and optimize process design and operation. The new graphical task editor provides easy drag-and-drop functionality and graphical visualization to the existing gPROMS task language, making it easy to define and verify complex operating procedures and startup policies for batch and other dynamic processes. Other new features simplify the creation of process flowsheets and reduce memory consumption.

gPROMS version 3.2
Version 3.2 of the gPROMS advanced process modeling (APM) software is used in the oil and gas, chemicals and petrochemicals, power generation, clean energy, food and beverage, consumer products, and pharmaceutical sectors. This release features improvements in the handling of discrete logic within the equation-oriented modeling environment, and contains numerous productivity, speed and robustness upgrades. These enhancements allow gPROMS library models to incorporate sophisticated supervisory controllers whose execution is completely transparent to end-users of the software. The software can detect over- and under-specification conditions and make intelligent suggestions for the choice of specification variables, as well as provide analysis and assistance for numerical troubleshooting during model construction and execution.

gPROMS Advanced Model Library for Gas-Liquid Contactors
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.
