HOW DOES THE TANKS MODEL GENERATE SPECIATED EMISSIONS?
The model offers several options for speciating emissions into their component parts. When the user is able to specify the properties and amounts of the liquids stored, the program relies upon Raoult’s Law and Dalton’s Law to estimate component emissions. If liquid properties are not known, Version 4.0 of TANKS has default liquid speciation profiles for crude oil and selected petroleum products. The last option uses tank headspace vapor speciation data for fixed roof tanks. The user must supply this data.
