analytical solution to the optimal capacity of a batch-storage network that suffers from sporadic shutdown of its units. Lutze and co-workers (DOI: 10.1021/ie302513y) address process integration at the phenomenon level and generate flowsheet options, using a decomposition-based solution approach. Marmolejo and Gundersen (DOI: 10.1021/ie302541e) propose a new graphical representation of exergy particularly suited for the design of low-temperature processes. Rong and coworkers (DOI: 10.1021/ie302495w) study the synthesis of a process for recovering artemisinin, which is obtained from plants and used as a drug for several diseases, including malaria.
he International Symposia on Process Systems Engineering (PSE) have been a triennial tradition since 1982. The series was arranged by the International Organization for Process Systems Engineering with representation from the Asia Pacific Confederation of Chemical Engineering, the European Federation of Chemical Engineering, and the Inter-American Confederation of Chemical Engineering. It has proved to be an attractive global platform for the PSE academics, researchers, and practitioners from all corners of the world for sharing advances in PSE education, research, and application. PSE2012, the 11th in the series, was held in the global village of Singapore during July 15−19, 2012. While the PSE community continues its focus on understanding, synthesizing, modeling, designing, simulating, analyzing, diagnosing, operating, controlling, managing, and optimizing a host of chemical and related industries using the systems approach, the boundaries of PSE research have expanded considerably over the years. The changes and challenges brought about by the increasing globalization and common global issues of water, energy, sustainability, and environment provided the motivation for the theme of PSE-2012: Process Systems Engineering and Decision Support for the Flat World. PSE-2012 involved nearly 340 contributions on modeling, simulation, design, optimization, operations, control, water, energy, environment, sustainability, biosystems, oil and gas, pharmaceuticals, education, industrial applications, and others. Short versions of these papers have been published in the Proceedings of PSE-2012.1 We invited extended versions of some papers that reflected key developments related to water, process/product design, sustainability, and process operations and optimization. These appear in this special issue, after the usual stringent review process of I&ECR.

PROCESS OPERATIONS AND OPTIMIZATION Xi and co-workers (DOI: 10.1021/ie302488v) propose an equation-oriented approach that optimizes a high-density polyethylene (HDPE) slurry process for a target molecular weight distribution. Moon and co-workers (DOI: 10.1021/ ie302509q) analyze flow patterns in a cyclone using computational particle fluid dynamics to understand deposit formation in a residue fluidized catalytic cracking process. Müller and coworkers (DOI: 10.1021/ie302487m) experimentally evaluate the operating conditions for a three-phase separation unit in a process for hydroformylation of long-chain alkenes. Shin and co-workers (DOI: 10.1021/ie302511d) analyze the explosion risks of mixtures of alternative clean fuels. Yoon and co-workers (DOI: 10.1021/ie3025104) propose a methodology for the safe layout of chemical processes based on an index that incorporates the risk to humans.
WATER Chen and co-workers (DOI: 10.1021/ie302521v) present a mixed integer nonlinear programming (MINLP) model to synthesize water networks that involve batch and semicontinuous units and operate cyclically. Majozi and Gololo (DOI: 10.1021/ie302498j) present a technique to optimize the pressure drop in cooling water systems containing multiple cooling towers. Shuhaimi and co-workers (DOI: 10.1021/ ie302427v) present a model of water polygeneration system that can be used to simultaneously minimize freshwater consumption and wastewater generation.

PROCESS AND PRODUCT DESIGN de Medeiros and co-workers (DOI: 10.1021/ie302507n) develop a simulation model for upgrading natural gas for offshore applications using gas−liquid hollow fiber contactors via aqueous alkanolamines. Eden and co-workers (DOI: 10.1021/ie302516v) report a new methodology that designs molecular structures with desired target properties. Ganguly and co-workers (DOI: 10.1021/ie303007n) optimize a phosphoric acid fuel cell (PAFC) stack, using a reduced-order model. Lee and co-workers (DOI: 10.1021/ie302404g) find an © 2013 American Chemical Society
SUSTAINABILITY
Bezzo and co-workers (DOI: 10.1021/ie302442j) highlight the importance of water and carbon footprints in the strategic design of biorefineries, using a multiobjective formalism. Cresmaschi and co-workers (DOI: 10.1021/ie302478d) use computational fluid dynamics (CFD) to simulate a flooded bed algae bioreactor and use an ANN surrogate model to maximize algae production. Floquet and co-workers (DOI: 10.1021/ ie302490y) assess the sustainability of an integrated hightemperature steam electrolysis process that converts biomass to liquid fuel. Tan and co-workers (DOI: 10.1021/ie302485y) present a targeting concept for heat-integrated resource conservation networks. Tan and co-workers (DOI: 10.1021/ ie302481h) extend the well-known pinch analysis technique to match carbon dioxide sources and storage sites in the context of carbon capture and storage. Kravanja and co-workers (DOI: 10.1021/ie302599c) propose a method to reduce the many environmental footprints to a minimum in the multiobjective optimization of biomass-based energy systems.
