Emission factors for metals from combustion of refinery fuel gas and residual fuel oil

Report no. 9/16: This report provides emission factors for nine metals (arsenic, cadmium, chromium, copper, lead, mercury, nickel, selenium and zinc) emitted to atmosphere during the combustion of refinery fuel gas in boilers and furnaces. It also provides a factor for nickel emissions from the combustion of refinery residual fuel oil.

These factors are considered to provide more representative average emission estimates than those provided in the reference commonly used for these factors (API Publication 348) as substantially more data have been used in their derivation.
