GasEvolutionModel Class

This model is used to calculate the emissions associated with the generation of a non-condensable gas as the result of a chemical reaction. The model assumes that the gas is exposed to the VOC, becomes saturated with the VOC vapor at the exit temperature, and leaves the system. The model also assumes that the system pressure is 760 mmHg, atmospheric pressure. This model is identical to the Gas Sweep model, except that the non-condensable sweep gas (usually nitrogen) is replaced in this model by a non-condensable gas generated in situ. It is important to note that if the generated gas is itself a VOS, non-VOS or TVOS, then the emission of this gas must be accounted for by a separate model, usually the Mass Balance model.

For example, if n-butyllithium is used in a chemical reaction and generates butane gas as a byproduct, the evolution of butane gas causes emissions of the VOC present in the system. These emissions can be modeled by the Gas Evolution model (to account for the emission of the VOC vapor which saturates the butane gas) and the Mass Balance model (to account for the emission of the VOC butane).
