Innovative pétrole nettoyer invention par un professeur de génie chimique-Travaux recevoir une reconnaissance internationale

A recovery ship carries a large tank filled with seawater. Une reprise navire transporte une grande cuve remplie d’eau de mer. When the ship approaches an oil slick, it opens a series of holes in the bottom of the tank; the movement of the ship’s hull forces the oil past the holes. Lorsque le navire se rapproche d’une marée noire, il ouvre une série de trous dans le fond de la citerne, le mouvement de la coque du navire forces de l’huile passé les trous. Because oil is less dense than seawater, it rises to the top of the tank and gradually displaces all the seawater. Parce que l’huile est moins dense que l’eau de mer, il s’élève vers le haut du réservoir et déplace progressivement l’eau de mer tous. The holes are then closed and the ship returns to dock to unload the oil. Les trous sont ensuite fermés et le navire retourne à quai pour décharger l’huile.

( PRWEB ) May 17, 2004 — Dr. Chaalal, Adjunct Professor of the Chemical Engineering and Process Department-United Arab Emirates University, has designed a tanker for recovering lost oil. (PRWEB) Mai 17, 2004 – Dr. Chaalal, professeur adjoint du Chemical and Process Engineering Department-Université des Emirats Arabes Unis, a conçu un navire-citerne pour la récupération de pétrole perdu.

A recovery ship carries a large tank filled with seawater. Une reprise navire transporte une grande cuve remplie d’eau de mer. When the ship approaches an oil slick, it opens a series of holes in the bottom of the tank; the movement of the ship’s hull forces the oil past the holes. Lorsque le navire se rapproche d’une marée noire, il ouvre une série de trous dans le fond de la citerne, le mouvement de la coque du navire forces de l’huile passé les trous. Because oil is less dense than seawater, it rises to the top of the tank and gradually displaces all the seawater. Parce que l’huile est moins dense que l’eau de mer, il s’élève vers le haut du réservoir et déplace progressivement l’eau de mer tous. The holes are then closed and the ship returns to dock to unload the oil. Les trous sont ensuite fermés et le navire retourne à quai pour décharger l’huile.

Explaining the technique, Dr Chaalal says the recovery ship carries a large tank filled with seawater. Explication de la technique, explique le Dr Chaalal la récupération navire transporte une grande cuve remplie d’eau de mer.

When the ship approaches an oil slick, it opens a series of holes in the bottom of the hull to connect the water in the tank to the water outside. Lorsque le navire se rapproche d’une marée noire, il ouvre une série de trous dans le fond de la coque à connecter l’eau dans le réservoir à l’eau à l’extérieur. Just like a glass full of water which is upturned in a filled sink. Tout comme un verre plein d’eau qui est chavirée dans un puits rempli.

The water in the tank does not flood out as long as the holes remain unchanged. L’eau dans le réservoir n’est pas comme les inondations longtemps que les trous restent inchangés. As the ship moves along, its specially designed hull shape forces any oil it encounters underneath the boat pass the holes. Comme le navire se déplace le long, sa coque spécialement conçu forme forces d’huile qu’il rencontre sous le bateau passer les trous.

« Because oil is less dense than seawater, it rises up through the holes to the top of the tank. » «Parce que le pétrole est moins dense que l’eau de mer, il se dresse à travers les trous en haut de la citerne. » Dr. Chaalal explains. Explique le Dr Chaalal. « As the oil builds up in the tank, it gradually displaces the seawater until it contains nothing but oil. The holes are closed and the ship returns to dock to unload its catch. » « Comme l’huile s’accumule dans le réservoir, il déplace peu à peu l’eau de mer jusqu’à ce qu’il ne contient rien, mais le pétrole. Les trous sont fermés et le navire retourne à quai pour décharger sa cargaison. »

Dr Mohamed said Dr Chaalal also demonstrated the technique using a 60cm long scale model in a tank containing a one-litre ‘slick’ of crude oil. Dr Mohamed a déclaré le Dr Chaalal également démontré la technique en utilisant une échelle de 60 cm modèle dans un réservoir contenant un litre-un « slick » de pétrole brut. To simulate sea conditions, the tank was agitated. Pour simuler les conditions de mer, le réservoir a été agité. In only a couple of minutes, the boat recovered 99 per cent of the oil. En quelques minutes, le bateau récupéré 99 pour cent du pétrole.

Dr Will Hendry, Operations Supervisor for Briggs Environmental Services, a counter-pollution specialist based in Aberdeen, Scotland, said the idea will certainly be welcomed by the oil industry. Dr Will Hendry, superviseur des opérations pour Briggs Environmental Services, un contre-la pollution spécialiste basé à Aberdeen, en Écosse, a déclaré l’idée sera certainement bien accueillie par l’industrie pétrolière.

What makes Dr. Chalal’s invention so desirable is that it does not use chemicals that can harm sea creatures and that Qu’est-ce qui rend M. Chalal l’invention est souhaitable afin de ne pas utiliser de produits chimiques qui peuvent endommager les créatures marines et que

most of the recovered oil should be reusable. la plupart des hydrocarbures récupérés devraient être réutilisables. It can simply be reloaded into tankers and recycled. Il peut simplement être rechargées dans les navires-citernes et recyclés.

The idea first occurred to Dr Chaalal when he was completing his doctorate studies at Newcastle Upon Tyne University in 1990. L’idée a eu lieu au Dr Chaalal quand il achevait son doctorat à Newcastle Upon Tyne University en 1990. On joining the United Arab Emirates University he met Dr Mamdouh Ghannam, who was supervising two students who had an interest in oil spills. En rejoignant l’Université des Emirats Arabes Unis, il a rencontré le Dr Mamdouh Ghannam, qui a été la supervision de deux étudiants qui ont un intérêt dans les déversements d’hydrocarbures. Chaalal took the opportunity to pursue his idea resulting in a successful laboratory demonstration in which 99 percent of a 1 litre ‘slick was cleared in two minutes. Chaalal a eu l’occasion de poursuivre son idée d’où un succès de démonstration en laboratoire dans laquelle 99 pour cent d’un 1 litre « nappe a été autorisé en deux minutes.

Omar Chaalal believes his idea can change the way of cleaning oil spills around the world. » If he is right then millions of birds, fish and mammals may owe their survival to a university professor. Omar Chaalal croit que son idée peut changer le mode de nettoyage des déversements de pétrole dans le monde. « S’il est juste alors des millions d’oiseaux, de poissons et de mammifères mai doivent leur survie à un professeur d’université.

Dr. Chaalal has been serving the Chemical Engineering Department for several years, and has taught many courses including Introduction to Chemical Engineering, Advanced Separation Processes, Chemical Engineering Reaction, Physical and Organic Chemistry. Dr. Chaalal a servi le Département de génie chimique pendant plusieurs années, et a enseigné de nombreux cours, y compris l’introduction de génie chimique, avancée des procédés de séparation, de réaction génie chimique, physique et chimie organique. He has contributed much to the research and has been involved in the publishing of many papers regarding the field of Environment and Chemical Engineering. Il a beaucoup contribué à la recherche et a été impliqué dans la publication de nombreux documents concernant le domaine de l’environnement et le génie chimique.
