Many oil and gas fields in the US, Canada and Russia keep chemicals containing sulfur, oxygen and nitrogen along with the general hydrocarbon mass, a practice which retains impurities than complicate processing and reduce consumable properties. This monograph describes the scientific basis for isolating and possibly using the light fraction (C2-C5) of mercaptans. The authors ...
