| Description: | Young and Beilby's 'Pentland' retort, 1881. The central feature of their retort was the adoption of a two-stage process of distillation, the shale passing continuously through a vertical retort, the upper portion of which was heated to a suitable temperature for the production of oil, while in the lower part a higher temperature was maintained and, in an atmosphere of steam, a larger percentage of the nitrogen of the shale was converted into ammonia. Other improvements were also embodied, but while the yield of crude oil showed no marked difference, that of sulphate of ammonia was in some cases almost doubled. The Inventors were William Young (1841-1907) of the Clippens Oil Works, Midlothian (not related to Dr. James Young) and George Thomas Beilby (1850-1924) (later Sir George) of Oakbank Works. |
