5-28 the following data are from the u. s. epa ap-42 emission factors for malt beverages. for a steam-heated brewers grain dryer, co 5 0.22, co2 5 53, and voc (ethanol) 5 0.73. the units for the emission factors in the epa tables are in lbs of pollutant per 1,000 barrels (bbl). a brewery produces about 7 million barrels of product per year. estimate the emissions of
(a) kg of carbon monoxide per year from fermenter venting
(b) kg of carbon dioxide per year from fermenter venting
(c) kg of vocs (ethanol) per year from fermenter venting
