various petroleum processes. The first two methods are only two commercially utilized routes to styrene production. Method 3 was practiced by Union-Carbide Corporation but later was replaced with a dehydrogenation process. Methods 4 & 5, involving chlorine, have generally been suffering from high cost of the raw materials and from the chlorinated contaminants in the monomer. Manufacture of styrene directly from petroleum streams is difficult and costly. The two commercially important routes to styrene

the client wants, then Générale will create a company that can. Générale and Lyonnaise have put France on the cutting edge of R&D on water purification, transport, and waste-water treatment. In Mery-sur-Oise, Générale has established the first chlorine-free water-treatment system in the world. In Tokyo, Lyonnaise researchers are working with the Japanese to develop compact water-purification plants using biological systems. The companies have also become leaders in emerging markets for “green”

of method. They realise its when they introduce or adapt a new method and when they replace an old method. I tested five parameters in order to evalue the new method. The two equipments have this parameters in common: glucose, potassium, sodium, chlorine and lactate. Page 1 sur 48 Travail de diplôme / Johana Aymon TABLE DES MATIERES 1. INTRODUCTION 2.

Aum Shinrikyo chemical and biological attacks in Tokyo with the March 2004 jihadist attacks in Madrid clearly demonstrates that explosives are far cheaper, easier to use, and more effective in killing people. The failure by jihadists in Iraq to use chlorine effectively in their attacks also underscores the problem of using improvised chemical weapons. These problems were also apparent to the Al-Qaeda leadership, which scrapped a plot to use improvised chemical weapons in the New York subway

Most countries report 100% treatment of their water supplies, whereas Cuba only reports 84%. Water treatment is typically done by chlorination for disinfection, but evidence suggests that the water is not being reliably chlorinated due to a lack of chlorine. The water supply system is unstable because pumps are in need of repair and because of frequent interruptions in the electrical supply needed to run the pumps. With respect to waste water, only 38% of the population is served by a waste water collection

question du blanchiment à l’aide de produits chlorés a représenté une problématique environnementale importante du secteur papier. Mais dans les années 1990 de nouveaux procédés limitant ces problèmes se sont développés : TCF (Totally chlorine free) ou ECF (Elementary chlorine free). Ceux-ci ont permis d’obtenir des effluents moins corrosifs tout en réduisant à des niveaux très faibles les éléments chlorés. Ils ont aussi autorisé le développement de circuits de recyclage de l’eau dans le processus de fabrication
