The US EPA requires hazardous waste incinerators to meet a standard of 99.99% destruction and removal of organic hazardous constituents injected into the incinerator, which is referred to as "four nines DRE". The efficiency is calculated by measuring the mass flow rate of organic constituents entering the incinerator and the mass flow rate of constituents exiting the incinerator stack, as shown in Figure 1. Draw a mass-balance diagram and determine the allowable quantity of contaminant in the exit stream if the incinerator is burning 1.2000 g/s of hazardous constituents. If the incinerator is 96% efficient in destroying the hazardous constituents, what scrubber efficiency is necessary to meet the EPA standard?

A control, process for a glass furnace will remove boron from the 1400 oF furnace by cooling the exhaust to 275 oF in an evaporative cooler to condense B2O3. The cooled exhaust will then pass through a ro verse-jet filter to remove suspended dust, including the B2O3 particulates. Draw a preliminary flow sheet for the process, indicating any auxiliary equipment needed, List any operating difficulties you think might arise with this system.
