Title
(EN) CONVERSION OF WASTE PLASTICS MATERIAL TO FUEL
(FR) CONVERSION DE DÉCHETS PLASTIQUES EN CARBURANT
Abstract
(EN)
A process is described for treating waste plasties material to provide at least one on-specification fuel product. Plasties material is melted (4) and then pyrolysed in an oxygen-free atmosphere to provide pyrolysis gases. The pyrolysis gases are brought into contact with plates (13) in a contactor vessel (7) so that some long chain gas components condense and return to be further pyrolysed to achieve thermal degradation. Short chain gas components exit the contactor in gaseous form; and proceed to distillation to provide one or more on-specification fuel products. There is a pipe (12) directly linking the pyrolysis chamber (6) to the contactor (7), suitable for conveying upwardly-moving pyrolysis gases and downwardly-flowing long-chain liquid for thermal degradation. There is a vacuum distillation tower (26) for further processing of liquid feeds from the first (atmospheric) distillation column (20). It has been found that having thermal degradation in the contactor and pyrolysis chamber and by having a second, vacuum, distillaton column helps to provide a particularly good quality on-specification liquid fuel.

La présente invention concerne un procédé destiné à traiter des déchets plastiques afin d'obtenir au moins un produit carburant répondant aux spécifications. Les matériaux plastiques sont fondus (4) puis pyrolysés dans une atmosphère exempte d'oxygène afin d'obtenir des gaz de pyrolyse. Les gaz de pyrolyse sont mis en contact avec des plaques (13) dans une cuve à contacteurs (7) de sorte que certains composants gazeux à chaîne longue se condensent et retournent pour être de nouveau pyrolysés afin d'obtenir une dégradation thermique. Les composants gazeux à chaîne courte sortent de la cuve à contacteurs sous forme gazeuse ; et passent à l'étape de distillation afin d'obtenir un ou plusieurs produits carburants répondant aux spécifications. Le dispositif comprend une conduite (12) liant directement la chambre de pyrolyse (6) à la cuve à contacteurs (7), appropriée pour transporter les gaz de pyrolyse se déplaçant vers le haut et le liquide à chaîne longue circulant vers le bas pour une dégradation thermique. Il comprend également une tour de distillation sous vide (26) destinée à traiter encore les charges d'alimentation en liquide provenant de la première colonne de distillation (atmosphérique) (20). Il s'est avéré qu'avoir une dégradation thermique dans la cuve à contacteurs et la chambre de pyrolyse et qu'avoir une seconde colonne de distillation sous vide aide à obtenir un carburant liquide répondant aux spécifications de qualité particulièrement bonne.
