Abstract
Mineral oils, shale oils, tar oils and the like are refined by a process comprising treating them with concentrated sulphuric acid (preferably of not less than 90 per cent by weight concentration) or with chloro-sulphonic acid in order to extract the more reactive components of the oil, and separating the solution (extract phase) from the treated oil (raffinate phase) by centrifuging before any noticeable chemical reaction (with subsequent solution of acid reaction products in the raffinate phase) has taken place. The acid remaining in the raffinate phase is then allowed to react chemically with the more reactive constituents present in this phase and the sludge thus formed is removed from the raffinate phase by centrifuging. Air may be blown through the raffinate while the chemical reaction is taking place and this air blowing may be continued until there is no noticeable formation of additional sludge and the sludge has been transformed into a state suitable for centrifuging. The agglomeration of the sludge may also be accelerated by the addition of oxides, hydroxides, or metal salts, preferably of metals belonging to the first and second groups of the periodic system. The de-sludged raffinate may be neutralized, for instance with lime, and the neutralization products removed by centrifuging, preferably while introducing water into the centrifuge. Specification 435,826 is referred to.
