Abstract:
Disclosed are methods and systems for removing a highly reactive polymer precursor such as carbonyls from a liquid hydrocarbon stream. Embodiments may disclose a method for removal of carbonyls from a liquid hydrocarbon stream comprising the steps of providing a liquid hydrocarbon stream containing carbonyls, providing a liquid bisulfite stream comprising an alkali metal bisulfite, and contacting the liquid hydrocarbon stream and the liquid bisulfite stream in a mass transfer device wherein at least a portion of the carbonyl reacts with the alkali metal bisulfite to form a solid adduct that is soluble in the bisulfite solution.
Abstract:
The present disclosure relates to a process for reducing the sulphur content of hydrocarbon feedstocks such as Natural Gas Condensate, Kerosene, Jet Fuel, Diesel, Vacuum Gas Oil and Fuel Oil. The process uses a tailored oxidation process comprising one or two oxidation steps to produce sulphoxides and/or sulphones. These sulphoxides and sulphones, whilst being still present in the liquid hydrocarbon streams, are subsequently extracted thereby producing a low sulphur hydrocarbon stream and optionally following further treatment of the sulphoxides and/or sulphones, produce a low sulphur aromatic hydrocarbon stream and an aqueous stream of sodium sulphite or sulphuric acid. The low sulphur hydrocarbon stream and low sulphur aromatic hydrocarbon stream may be individually recycled or combined for recycling.
Abstract:
Methods and apparatuses for processing hydrocarbons are provided. In one embodiment, a method for processing a hydrocarbon stream includes feeding a hydrocarbon stream including amine and mercaptan to an extraction zone. The method includes contacting the hydrocarbon stream with an alkaline stream in the extraction zone to convert the mercaptan to a mercaptide. Further, the method includes contacting the hydrocarbon stream with water in the extraction zone to remove the amine from the hydrocarbon stream.
Abstract:
Systems and methods for conditioning synthetic crude oils are provided herein. The systems and methods described herein subject the synthetic crude to one or more process solutions to provide conditioned synthetic crude exhibiting, for example, a reduced TAN.
Abstract:
A system and method for cleaning sulfur and other pollutants from bunker oil to be used for fuel in large cargo ships is described. Preferably, the system includes two or more stages having a mixer to create an emulsion of oil and water. One or more treatment chemicals are added to the water before it is mixed with the oil in order to assist in separating the sulfur from the oil and freeing it up so that it can combine with various other molecules present in the water or be dissolved in the water. The emulsion may pass through a microcavitation chamber as well as an electrolysis reactor chamber in order to further clean the fuel oil by removing additional sulfur content. The clean fuel is sent to a fuel service tank for use in a diesel engine combustion cycle.
Abstract:
A reaction system and method for removing heteroatoms from oxidized-heteroatom-containing hydrocarbon streams and products derived therefrom are disclosed. An oxidized-heteroatom-containing hydrocarbon feed is reacted in a reaction system thereby forming non-ionic hydrocarbon products. The products derived therefrom are useful as transportation fuels, lubricants, refinery intermediates, or refinery feeds.
Abstract:
Methods for processing algal oils are provided. In an embodiment, a method for removing a contaminant from an oil includes contacting the oil with a base to form an intermediate solution. Further, the method includes contacting the intermediate solution with an acid to form an acidic solution. The method separates the acidic solution into an oil portion and an aqueous waste portion including the contaminant.
Abstract:
A method of upgrading a heteroatom-containing hydrocarbon feed by removing oxidized-heteroatom contaminants is disclosed. The method includes contacting the oxidized-heteroatom-containing hydrocarbon feed with a caustic and a selectivity promoter, and removing the heteroatom contaminants from the heteroatom-containing hydrocarbon feed.
Abstract:
The present invention relates to a method and to a plant for dehydration of a liquid or gaseous effluent, wherein the following stages are carried out: neutralizing the effluent with at least one of the following brines: soda brine, potash brine, or mixtures thereof, dehydrating the neutralized effluent on soda or potash briquettes, collecting the brine resulting from dehydration and using it in the neutralization stage (2).
