How Should Shale Gas Extraction Be Taxed? [PDF]

open access: yesIMF Working Papers, 2017
This paper suggests that the environmental and commercial features of shale gas extraction do not warrant a significantly different fiscal regime than recommended for conventional gas. Fiscal policies may have a role in addressing some environmental risks (e.g., greenhouse gases, scarce water, local air pollution) though in some cases their net ...

Gas extraction of a western sub-bituminous coal. Final report. [Supercritical gas extraction]

open access: yes, 1978
The British National Coal Board has developed a technique for the extraction of UK bituminous coals with supercritical fluids, whereby an extract is obtained which can be hydrocracked to a distillate oil rich in benzene derivatives, together with a reactive char suitable for gasification or combustion. No hydrogen is needed for the extraction, the need

DETERMINATION OF HALOTHANE IN GAS, BLOOD, AND TISSUES BY CHEMICAL EXTRACTION AND GAS CHROMATOGRAPHY

open access: yesBritish Journal of Anaesthesia, 1971
SUMMARY The method is an adaptation of those of Wolfson, Ciccarelli and Siker (1966) and of Cervenko (1968). Halothane is extracted into Analar carbon tetrachloride which contains chloroform as a trace impurity. This chloroform is used as an internal standard.
