ABSTRACT:
A system and method for conditioning and recycling inert gases which are used in a plasma furnace. The method comprises the steps of receiving the gas that is output from the plasma furnace and cooling the gas to a desired temperature. Substantially all the dust is removed from the gas and then the gas is compressed to the desired pressure using an oil-flooded screw compressor. Any oil which is introduced by the compressor is removed from the gas and an alarm is provided to signal a high oil level. Substantially all water vapor in the gas is removed and the gas is filtered to remove any remaining dust and small particulates. The amounts of water vapor and oxygen in the gas are monitored. The gas is then recycled to the plasma furnace.
