Research output: Patent › Patent

Abstract

The invention relates to a process for treating a raw material containing aluminium or a similar metal melting at a low temperature and organic matter, including metal separation. The invention is particularly intended for the treatment of liquid container rejects consisting of aluminium foil, polymer material and possible fibre residues in order to recover the aluminium and to utilise the organic matter as a fuel. In accordance with the invention, the raw material (5) is introduced in a bubbling fluidised bed (3), where the organic matter is gasified at a temperature higher than the melting point of the metal present. The gas removed from the fluidised bed and the entrained metal are subsequently cooled to a temperature below the melting point of metal by admixing a cooling medium such as water (6) in the gas flow. The solid metal particles are eventually separated from the gas e.g. with a cyclone (8) and the gas flow is possibly filtered (11) before combustion.
