ABSTRACT
Fanavaran petrochemical company is located on the shore of Persian Gulf on west south of Iran, Imam Khomeini Bandar, petrochemical special economic zone with of 25 hectares area. Two units of this company, methanol unit with production capacity 1000000 tons/ years andmonoxide carbon unit with 140000 tons/years were studied for determination and emission factories of SO[2], CO[2], CO, NO, NO[2], NO[x] Gases. With attention to project goals, for implementation of this project 14 months took into from April 2008 till June2009. For goals provide of mentioned research on this basis, 32 case sampling were done from 3 emission sources by using of direct reading device of gas concentration according to standard methods of United State Environmental Protection Agency Results of the study indicate that concentration of issued pollutant gases from these units is in the level lower than Iran department of environment standard level. The total amount of emission Factory of SO[2], CO[2], CO, NO, NO[2], NO[x] gases diffused from these units are11.7 X 10[-6], 81/8 X 10[-6], 0.14 X 10[-6], 431.5 X 10[-6], 19.2 X 10[-6], 681.2 X 10[-6] kg /tons million production in a year respectively. Parameters which optimization is performed in accordance with them, include of additional air percentage, exit air temperature from pre heater, and fuel type, in fact with regarding these 3 factor's. effects, the work is done in a manner that the amount of pollutants diffusion is near to minimum and the selected best fuel
