We are installing a Liquid Waste Incinerator and is in the stage of Bids evaluation. Environmental regulations stipulate limit on 'Visual Emissions' as "10% Opacity" for Flue Gas. In order to meet this, one leading Supplier used cooling of scrubber water for bringing down the water vapor content of flue gas, consuming huge CW. But we are very short of CW supply. The Supplier assumed Water Vapor for opacity limit saying it contributes to opacity. Opacity definition (elsewhere) refers to only air contaminants i.e. SO2, NOx, PM etc. and not Water Vapor. The supplier suggested to get official clarification/waiver from Regulatory body if Opacity should exclude water vapor, in which case CW load can be brought down significantly.
Forum folks are requested to through some light and offer advice.
