Some organic chemical plants employ closed-loop sampling which may help to reduce fugi- tive emissions. The flaring of vapors vented from various vessels or equipment is another technique which is used by some plants (particularly those produc- ing toxic or hazardous chemicals) that will reduce fugitive emissions.

A distinct set of PASs has been developed for semi-volatile organic chemicals (SVOCs). The term SVOCs comprises organic molecules that can occur to a significant extent in both the gas-phase and condensed phases, which corresponds to the vapour pressure range of approx. 10 −1 to 10 −6 Pa. The group of SVOCs comprises a large number of
