Title: A method of and means for desulphurising mineral oils and spirits
IPC: C10G27/04
Filed: 1922-01-25
Abstract: 196,680. Nesfield, A. C. Jan 25, 1922. Mineral oils, purifying.-Mineral oils are desulphurized by impregnating them with hydrochloric acid gas and air or a mixture of hydrochloric acid gas, hydrogen, and air, washing the treated oil with caustic soda or lime water, and filtering by centrifuge or otherwise to remove the sulphur &c. The oil may be treated in gaseous form, or may be exposed to the gases as a film or spray, or the gases may be bubbled through it. Crude shale oil or spirit may be distilled into two fractions terminating at about 392‹ F. and 750‹ F., each fraction being separately treated. To obtain white spirit, the oils after washing with alkali may be further washed with 2 per cent of sulphuric acid; if emulsification occurs, the oil is washed with sodium chloride solution. The process may be carried out in the apparatus described in Specification 183,527, or in that shown in the Figure. The oil passes into the reaction chamber a, which is fitted with wire gauze screens h, bv the pipe b, and the gas and air by pipe c. Reduced pressure is obtained by a vacuum pump connected to the opening d, thus ensuring passage of the gaseous mixture through the chamber. The oil passes through pipe e to the settling tank g. The Provisional Specification describes the treatment of distillates with chlorine or allied gas, or hydrochloric acid gas or a mixture of hydrochloric acid gas and hydrogen. The distillate is then washed with sulphuric acid, and any deposit is removed; the oil is again washed with caustic soda, allowed to settle and distilled, the distillate being treated with ozone or other oxidizing agent, and allowed to settle. After further washings with acid and alkali, the distillate is heated to 200‹-220‹ F. in the case of spirit, and to 750‹ F. in the case of oil. When the sulphur occurs at sulphuretted hydrogen, sulphur dioxide may be used to decompose it, the resulting 'acid being removed by lime or caustic soda.
