Increasing dependence on high sulphur ‘sour’ crude oil combined with increasingly stringent requirements on the sulphur content of processed fuels has rapidly made sour crude and sour gas the major commercial sources of sulphur. Production is outstripping demand, resulting in large S stockpiles. Since other chalcogens, Se and Te in particular, could be concentrated by the same processes that concentrate S, sour crude has been suggested as a possible source of Te for photovoltaics. The possibilities are explored for both Se and Te in the present paper. Suppressed concentrations of Se in crude oil and gas relative to sulphur and the even lower likely concentrations of Te mitigate against this prospect. Copyright © 2011 John Wiley & Sons, Ltd.
