temperatures in the range 900-1200C at which all the compounds areconverted to carbon dioxide. Any fine metal or mineral particles are

blown upwards into a cooler region of the chamber, they are oxidisedand then recovered by passage through a cyclone/filter assembly.Particles down to one micron are recovered in this process which can

be as much as 99.5 per cent efficient, while toxic gases are treated usingstandard proprietary techniques. The throughput of the plant is 0.2 tonneof waste per day and is capable of reclaiming gold from grease, platinumfrom whale oil and nickel from fat. In the last process an electrolyticroute converts the nickel oxide to nickel sulphate.

9.9.7 Hot organic stripping

Steel-based shop fittings require an electrostatically applied epoxy- polyester powder. Due to stricter emission control for the protectionof the environment an existing 150 kW gas fired pyrolysis furnaceoperating at 850C was replaced by a 30 kW electric organic solvent

stripping tank. The resultant resin/powder sludge is removed byconventional disposal methods. The electric furnace operates at onlyabout 90C which ensures that the jigs are no longer metallurgicallyweakened, and now they only need to be replaced on a 'wear and tear'

basis instead of having to be routinely changed every month. The energysavings resulted in a payback of 27 months; the product quality and theworking, as well external environments have been considerablyimproved.

9.9.8 Pure gas generators

A method for producing on site nitrogen, hydrogen and air has beendeveloped in the NITROX system, shown schematically in Figure 9.28.

Air passes through a motor driven compressor and then through afilter to remove water droplets and dirt. A carbon molecular sieve trapsoxygen, water, carbon dioxide and hydrocarbons allowing purenitrogen to pass through to a holding reservoir. Another device, zeolitesieve, traps water allowing pure dry air to be stored to a second reservoir.After a fixed time the sieves are back flushed and automatically

regenerated. The gases pass through flow controllers to outlet points for use.
