Integration of modular process simulators under the Generalized Disjunctive Programming framework for the structural flowsheet optimization

The optimization of chemical processes where the flowsheet topology is not kept fixed is a challenging discrete-continuous optimization problem. Usually, this task has been performed through equation based models. This approach presents several problems, as tedious and complicated component properties estimation or the handling of huge problems (with thousands of equations and variables). We propose a GDP approach as an alternative to the MINLP models coupled with a flowsheet program. The novelty of this approach relies on using a commercial modular process simulator where the superstructure is drawn directly on the graphical use interface of the simulator. This methodology takes advantage of modular process simulators (specially tailored numerical methods, reliability, and robustness) and the flexibility of the GDP formulation for the modeling and solution. The optimization tool proposed is successfully applied to the synthesis of a methanol plant where different alternatives are available for the streams, equipment and process conditions.

An alternative disjunctive optimization model for heat integration with variable temperatures

This paper presents an alternative model to deal with the problem of optimal energy consumption minimization of non-isothermal systems with variable inlet and outlet temperatures. The model is based on an implicit temperature ordering and the “transshipment model” proposed by Papoulias and Grossmann (1983). It is supplemented with a set of logical relationships related to the relative position of the inlet temperatures of process streams and the dynamic temperature intervals. In the extreme situation of fixed inlet and outlet temperatures, the model reduces to the “transshipment model”. Several examples with fixed and variable temperatures are presented to illustrate the model's performance.

Humanitarian Visas: Option or obligation?. CEPS Liberty and Security in Europe No. 68, 27 October 2014

Third-country nationals seeking protection have no EU-wide legal channels at present for entering EU territory and triggering protection mechanisms under the Common European Asylum System. As a result, many embark on hazardous journeys, with concomitant risks and loss of human life. The absence of ‘protection-sensitive’ mechanisms for accessing EU territory, along with EU external and extraterritorial border and migration management and control, undermine Member States' refugee and human rights obligations. Humanitarian visas may offer a remedy in this regard by enabling third-country nationals to apply in situ for entry to EU territory on humanitarian grounds or because of international obligations. This study asks whether the existing Visa Code actually obliges Member States to issue humanitarian visas. It also examines past implementation of humanitarian visa schemes by Member States and considers whether more could be done to encourage them to make use of existing provisions in EU law. Finally, with a Commission proposal for Visa Code reform on the table, it asks whether there is now an opportunity to lay down clear rules for humanitarian visa schemes.
