(1 point) You recommend that the company installs a wet scrubber to control particulate (PM) emis- sions. This involves spraying water on the exhaust gases, so that most of the particles leave in the water not the gas. The concentration of particles after combustion (in the influent gas) is 500µg/m³, the removal efficiency (nscrub) is 95%, the gas flow is 15 m³/s and the water flow is 1 m³/s. What is the rate of PM in the slurry (sludge waste) leaving the scrubber? Hints: removal efficiency (all one media, gas or liquid) n = PMin - PMout PMin x 100% Conservation of mass: all PM either ends up in gas or slurry. M M Concentration: = V Q PMin (scrubber) _g/d The tricky part here is keeping gas and liquid flows straight. PMout (gas) _g/d PMout (slurry) g/d _mg/m³ Concentration PMout slurry
