“…Sadiq et al [36] used FCP for the management of drilling waste disposal in offshore to determine the best discharge scenario considering risk, cost and technical feasibility criteria. The FCP is a step-by-step procedure of regrouping of a set of various basic indicators to form a single indicator [30]. Generally, the FCP is advantageous to the decision-makers in solving problems of multiple attributes and conflicting objectives.…”

“…But its application restricted to early stage design. Palaniappan et al [30] developed a systematic methodology to integrate inherent safety and environmental impact assessment. The study provides a unified framework for hazards and pollution analysis by focusing on process materials and their interactions with process units and conditions.…”

“…The study provides a unified framework for hazards and pollution analysis by focusing on process materials and their interactions with process units and conditions. A guide wordbased alternative generation technique, which meshes Palaniappan et al's [30] study with inherent safety and waste minimization principles, was proposed. The automated tool called iBDT, was implemented as an expert system and successfully tested on an acrylic acid process.…”

“…The chemical process industry, due to its high complex nature, is facing major challenges in responding to the political and social imperatives of continuous improvements in its environmental performance while at the same time ensuring its economic and fi nancial validity. However, several attempts have been made to integrate environmental and health considerations with economics in early stages of process design (Chen and Shonnard, 2004;Kheawhom and Hirao, 2004;Palaniappan et al, 2002;Sharrat, 1999). A variety of environmental indicators have been used in the environmental assessment of chemical processes from simple mass balance indices to more complicated methods based on multiple media, multiple exposure pathways, and multiple categories of impacts.…”

of substances to the environment and thus can produce misleading results. Therefore, emission based indicators are more accurate in representing actual impacts.Today, detailed process design tasks involve simulation, evaluation and optimization of the entire process. In fact, optimization is one of the most important steps in any chemical process design. Over the past decade, optimization of environmental performance has started to incorporate alongside traditional economic criteria. Several systematic methodologies are available for detailed characterization of environmental impacts of chemicals, products and processes and have been incorporated into the design and optimization of chemical processes. The most commonly used methods are Life Cycle Assessment (LCA) (Azapagic and Clift, 1999a, b;Azapagic, 1999), Methodology of Environment Impact Minimization (MEIM) (Stefanis and Pistikopoulos, 1997), Waste ReductionIncreasing social pressure and strict legislations have resulted in changing the approach of traditional design practices to incorporate multiple objectives in the design of process plants. Distillation is one of the major operations in the chemical process industry that is widely used for purifying products or recovering solvents or separation of valuable reactants from waste stream. In this paper, a procedure for multi-objective optimization is discussed with the help of a distillation unit from hydrocarbon recovery plant of a distillate fraction process. The procedure developed here consists of four stages and is based on current design tools. The aim is to support decisions during design phase and optimize the process variables in order to generate a process with improved economics along with satisfaction of environmental objectives. Total potential environment impact and total annualized cost are used as indicator for environmental and economic objectives, respectively. La pression sociale croissante et les législations strictes ont eu pour effet de modifi er la manière traditionnelle de concevoir les pratiques de façon à inclure des objectifs multiples dans la conception des installations de procédés. La distillation est une des opérations importantes de l'industrie des procédés chimiques et est largement utilisée pour purifi er des produits ou récupérer des solvants, ou encore pour séparer les réactifs intéressants dans les courants de résidus. On analyse dans cet article une méthode d'optimisation à objectifs multiples à l'aide d'une unité de distillation venant d'une installation de récupération d'hydrocarbures d'un procédé de fraction de distillat. La méthode mise au point ici consiste en quatre phases et utilise des outils de conception courants. Le but est d'appuyer les décisions lors de la phase de la conception et d'optimiser les variables de procédés afi n de fournir un procédé offrant de meilleures économies ainsi que la satisfaction de répondre à des objectifs environnementaux. L'impact environnemental potentiel total et le coût annualisé total sont utilisés comme indicateurs pour les obj...
