pollution loading of generator set

capacity: 550 kw

frequency: 60 Hz

fuel: diesel oil

consumption: 157 liters per hour

assuming that the generator set shall be used for an average of 1 hour per week, its annual fuel consumption(APC) shall be:

AFC = 157 liters/hr * 1 hr/week * 52 weeks/yr

= 8164 liters/yr or 2157 gallon/yr

using table in AP-42 5th edition: item II. internal combustion, sub-item a diesel ; <600 hp or 588.24 kw

the emission factors are:

particulate matters(PM) = 41.49 lbs/1000 gallons of fuel burned

carbon monoxide(CO) = 127.1 lbs/1000 gallons of fuel burned

nitrogen oxide(NO) = 590.2 lbs/1000 gallons of fuel burned

sulfur oxide(SO) = 38.31 lbs/1000 gallons of fuel burned

volatile organic compound(VOC) = 48.18 lbs/1000 gallons of fuel burned

pm loading annually

PM = 2157 gals/yr * ((41.49 lbs)/(1000 gals)) * ((1 metric ton)/(2200 lbs)) = 0.0407 metric ton/yr

CO loading annually

CO = 2157 gals/yr * ((127.1 lbs)/(1000 gals)) * ((1 metric ton)/(2200 lbs)) = 0.125 metric ton/yr

NOx loading annually

NOx = 2157 gals/yr * ((590.2 lbs)/(1000 gals)) * ((1 metric ton)/(2200 lbs)) = 0.579 metric ton/yr

SOx loading annually

SOx = 2157 gals/yr * ((38.31 lbs)/(1000 gals)) * ((1 metric ton)/(2200 lbs)) = 0.037 metric ton/yr

VOC loading annually

VOC = 2157 gals/yr * ((48.18 lbs)/(1000 gals)) * ((1 metric ton)/(2200 lbs)) = 0..040 metric ton/yr

that is my solution and i cant find a way to make its final unit mg/Ncm please help

thanks in advance :) and i wish you luck and can get the answer :-D
