Fuel Oil With 0.5% Sulfur Content Author: Mauro Capocelli – Chemical Engineer – Researcher –University UCBM – Rome (Italy) 1.Theme Description The presence of sulfur compounds in fuel oils causes concern both during refining processes (due to catalyst deactivation and … Need this product? The process of making solutions of sulphur in mineral oil which consists in dissolving sulphur in a solvent at a temperature slightly above the melting point of sulphur, allowing the solution to cool and precipitate sulphur, and adding sulphur so precipitated to a mineral oil heated to a temperature somewhat below the melting point of sulphur. These kinds of steels are often used in several parts of refinery units. Assay. Either a light mineral oil or lard oil can be advantageously used as a sulphur solvent. Another disadvantage is that the stain made by the lubricant on the metal is difficult to remove. The process of making solutions of sulphur in mineral oil which consists in dissolving sul0 phur in a solvent at a temperature of about 2500 to 2650 F., allowing the solution to cool and precipitate sulphur, and adding sulphur so precipitated to a mineral oil heated to a temperature of about 150°. Proper Shipping Name: Sulfur Also, the sulphur compounds in the lubricant give it a disagreeable odor and are poisonous, causing painful skin irritations. Login to view pricing and place your PCCA order. These solutions are of a light yellow color and quite transparent. UN Number: UN1350 What I claim is: 1. Solubility and reactivity of sulfur dioxide in various oils. 2. PG:III. Sulphur has been found to be very effective for these purposes. Privacy Policy Other sulphur solvents which will take a substantial quantity of sulphuu' into solution at from 250° to 2650 and from which a substantial quantity of sulphur will precipitate upon cooling may be employed. 4. Elemental sulfur is a bright yellow, crystalline solid at room temperature. The method heretofore commonly employed has been to add to mineral oil a sulphurized fatty oil which is produced by heating a mixture of sulphur and oil for a considerable length of time to a temperature of about 450* F. Lubricating compositions so made are of very dark color, almost black, and a considerable portion of the sulphur is chemically combined with the oil. The possible role of such interactions between SO2 and oils will be examined similarly. Proper Shipping Name: Sulfur Sulfur (in British English: sulphur) is a chemical element with the symbol S and atomic number 16. The present invention has for its object to provide a method of making stable solutions of sulphur in mineral oil which contain a percentage of sulphur at least as high as obtained by the use of sulphurized fatty oils, which is of light color, transparent, odorless, and non-poisonous. Roberts (1997) states that elemental sulfur freezes at 119°C at atmospheric pressure, but the freezing point decreases by increasing H2S concentration in the sour-gas. Sulfur removal from crude oil and hydrocarbons Caustic washing method for oil desulfurization. International Water Solubility of elemental sulfur (orthorhombic S 8) at 25°C in organic solvents (data in mass-%): Ethanol = 0.066. VERY FINE, PALE YELLOW, AMORPHOUS OR MICROCRYSTALLINE POWDER. The process of the present invention consists in first converting the sulphur into a form more readily soluble in mineral oil and then dissolving the sulphur in mineral oil. A small quantity of the lighter fractions of mineral oil does not injuriously affect the lubricating properties of a mineral oil lubricating composition. <=0.5 % max. I have discovered that if sulphur be dissolved in a solvent at a temperature slightly above the melting point of sulphur but at temperatures below that which the sulphur changes to a dark brown color, the sulphur which is precipitated upon cooling of the liquid is much more soluble in mineral oils than any commercial forms of sulphur. Furthermore, it is to be understood that the particular procedure set forth is presented for purposes of explanation and illustration and that various procedures can be followed without departing from ,my invention as defined in the appended claims. 21-3, cr represents the concentration of the solid sulfur dissolved in the gas expressed as mass per uni… & Terms of Use. The herein described method of making a stable solution of sulphur in a mineral oil which comprises dissolving the sulphur in an oil at temperature slightly above the melting point of sulphur, allowing the solution to cool and precipitate sulphur, and adding sulphur so precipitated to mineral oil at a temperature below the melting point of sulphur. The crystalline sulphur precipitate will readily dissolve in the oil and remain in solution after the oil is cooled. Solutions of sulphur in mineral oil containing from 2% to 5% sulphur can readily be made by the method above described. The crystalline sulphur precipitate will readily dissolve in the oil and remain in solution after the oil is cooled. This invention relates to a method of producing a soluble sulphur and more particularly to a method of producing stable solutions of sulphur in mineral and other oils. generation. Domestic & Canada: It is abundant, multivalent and nonmetallic. IS ODORLESS AND TASTELESS. Examples of such chemical compounds are tricresyl phosphate and chlorinated paraffin, either 'of; which may be employed as the solvent for sulphur. If the solvent is undesirable in the lubricating composition, the sulphur can be filtered out and washed prior to its addition to the lubricating oil. CLASS 4.1: Flammable solid. Of course, sulfur values as low as 0.2% are enough to create sulfidation corrosion in plain steels and low alloy steels.
