Objetivo
To demonstrate the feasibility of producing marketable fuels from scrap tyres on a commercial scale by pyrolysis.
Technical feasibility demonstrated but plant unable to achieve full continuous production and in financial difficulty. Currently shut down awaiting resolution of these difficulties and further modifications.
Tyres are heated in an oxygen free atmosphere to produce a light fuel oil, good quality solid fuel and a high grade steel scrap. The originality of the technology lies in its ability to treat a solid feedstock (tyres) as a source of hydrocarbons and to cope with the unique mechanical handling problems posed by such a feedstock. All types of tyres undergo a coarse size reduction and are then passed via a seal into the reactor. Hot gases containing no oxygen pass in counter current through the bed of tyres causing pyrolysis to occur. These gases carry with them the vaporized gaseous by-products of pyrolysis, including oil, in the vapour phase.
The vaporized mixture leaves the reactor and is cooled, condensing the oil which is collected in the base of the Quench Tower. This oil is then removed, its specification checked and adjusted as necessary. The gas is used to sustain the process. A carbonaceous solid fuel and steel scrap, the solid by-products of pyrolysis are continuously removed from the reactor by a novel extraction device, and the two components separated and passed to product storage.
The process is seen as having particular application in the European Community where a major waste disposal problem exists with regard to scrap tyres and alternative energy sources are of particular value.
