Recuperative aluminium recycling plant. A demonstration at J. McIntyre (Aluminium) Ltd. [Nottingham (GB)]

Abstract

Direct energy savings worth up to 470,000 pounds/year are being achieved by J McIntyre (Aluminium) Ltd in the United Kingdom as a result of the development of a recuperative aluminium recycling plant. The overall design incorporates a novel version of a closed-well furnace coupled with a radically improved design of dry hearth furnace. The plant not only treats clean scrap more efficiently than at present, but will also treat contaminated scrap which has not previously been recycled in an environmentally acceptable way. This is because the plant incorporates fume pyrolysis, afterburning of organics, recuperation and fume treatment. At 1987 prices the total installed plant cost was 1.3M.pounds. The direct energy saving at 1987 fuel prices was between 294,000 and 470,000pounds/year. Also, the improved melting technique has reduced metal lost as dross by 2 - 8% (420 -1,680 tonnes/year) when compared to other furnace operations. The improved metal recovery (1987 prices) was worth a further 400,000 pounds - 1,600,000 pounds. Taking median figures for the total fuel-plus-metal savings results in a payback on the project of only 14 months, some six months less than anticipated. Other consequential benefits which have also helped in reducing operating costs have been improvements in output  More>>
