摘要: Described herein are methods and systems for performing liquid-liquid extraction in bulk tankage. According to certain embodiments, the liquid-liquid extraction can occur in a bulk tank via a circulation loop, in which a solvent mixture is injected with the hydrocarbon ahead of mix valves on the circulation loop. According to other embodiments, a misting system is installed in the vapor or head space of bulk tankage. The misting system distributes small micro-drops of a solvent mixture so as to cause a uniform lay down over the entire top surface area of hydrocarbon. The solvent mixture migrates from the top surface of the hydrocarbon to the bottom of the bulk tank, reacting during migration to cause liquid-liquid extraction.

摘要: Systems and processes for removing organic acids from liquid hydrocarbon product streams are provided. The systems and processes can include injecting an ammoniated water wash into a liquid hydrocarbon product stream, such as an effluent stream from a methanol conversion process, and subsequently separating the treated liquid hydrocarbon product stream from the wash water. The addition of ammonia can reduce the amount of water wash by an unexpected amount.

摘要: A process for the removal of residual sulfur compounds from rich liquid caustic is disclosed where a single column containing two reaction zones catalytically oxidizes mercaptans to disulfide oils. The second reaction zone utilizes a bundle of vertical hanging fibers and is maintained as a gas continuous phase comprising from about 20% to about 100% by volume vapor. This process is especially useful as part of a hydrocarbon desulfurization process flow scheme.

摘要: A process for reducing TAN of hydrocarbon feed oil, comprising: a. combining alkaline earth metal, in an aqueous solution having a pH of 10 to 14, with the hydrocarbon feed oil to make a mixture; b. vigorously mixing the mixture; c. precipitating a metal-naphthenate salt; and d. removing the metal-naphthenate salt to reduce the TAN by 50 to 100%; wherein a weight ratio of the hydrocarbon feed oil to the aqueous solution is from 0.25:1 to 20:1. Also, a process for reducing TAN, comprising: a. combining an inorganic alkaline earth metal salt having a water solubility at 20° C. from 35 to 150 g/100 g water, in an aqueous solution having a pH of 10 to 14, to make a mixture; b. precipitating a metal-naphthenate salt; c. collecting the metal-naphthenate salt at an interface between an oil phase and an aqueous phase; and d. removing the metal-naphthenate salt.

摘要: 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.
