The diagram shows the complete process from the original shale through the various treatments and distillations and showing the end products. The process can be conveniently considered in two stages. The raw oil-shale is distilled/heated in retorts in the absence of air and in the presence of steam. This allows the shale to undergo decomposition and distillation into crude oil and ammonia. The second stage is refining the crude oil. The object is to obtain from the crude oil various types of refined oil and wax as required by the prevailing markets at the lowest possible working cost and with the smallest amount of capital spent on refining plant.
