| Description: | The scrubber naptha is an original sample from the Pumpherston Oil Company Limited at Mid-Calder, a leading company in the former Scottish oil-shale industry. British Geological Survey Petrology Collection sample number MC 7715. Scrubber naptha is a product of the first process the raw oil-shale undergoes, namely the heating in the retorts. The gases are led off to the condensers where the ammoniacal liquor and crude oil flows into a separator while the uncondensed gasses are led to two scrubbers, one a water scrubber to remove the remaining ammonia and the second an oil scrubber to remove the naptha. In the oil scrubber a descending spray of mineral oil absorbs the naptha which is then heated to dirve off the naptha which is then condensed into steam and raw scrubber naptha, the latter ready for refining. |
