Refining

Definition and stakes

Albert Lidgett,  Petroleum

“ The refining operations consist of three distinct branches: (1) the distillation, (2) the extracting of paraffin and refining, and (3) the chemical treatment. When only a small percentage of the low boiling fractions 55 56 has to be removed from the crude oil, the process is known as “topping,” and a convenient form of apparatus for the purpose is the tower still. This consists of a vertical cylinder fitted with perforated plates resting at intervals on pipes through which superheated steam travels. ”

Jacques W. Redway,  Commercial Geography

“ Sugar Manufacture.—Sugar manufacture includes three processes—expressing the sap, evaporating, and refining. The first two are carried on at or near the plantations; the last is an affair requiring an immense capital and a most elaborately organized plant. The refining is done mainly in the great centres of population at places most convenient for transportation. The raw sugar may travel five or ten thousand miles to reach the refinery; the refined product rarely travels more than a thousand miles. ”
