摘要： It has been discovered that metals and/or amines can be removed or transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains water-soluble hydroxyacids. Suitable water-soluble hydroxyacids include, but are not necessarily limited to glycolic acid, gluconic acid, C 2 -C 4 alpha-hydroxy acids, poly-hydroxy carboxylic acids, thioglycolic acid, chloroacetic acid, polymeric forms of the above hydroxyacids, poly-glycolic esters, glycolate ethers, and ammonium salt and alkali metal salts of the hydroxyacids, and mixtures thereof. The composition may also include at least one mineral acid to reduce the pH of the desalter wash water. A solvent may be optionally included in the composition. The invention permits transfer of metals and/or amines into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. The composition is particularly useful in treating crude oil emulsions, and in removing calcium and other metals therefrom.

摘要： A demulsifying agent may be added to a hydrocarbon stream in an effective amount where the hydrocarbon stream includes a plurality of solids. The demulsifying agent may be added to the hydrocarbon stream at a location that is upstream from a desalter. The demulsifying agent may water-wet at least a portion of the solids for subsequent separation of the solids from the hydrocarbon stream. The demulsifying agent may be or include but is not limited to at least one maleic acid derivative, such as di-lauryl succinate, dioctyl succinate, di-hexyl succinate, octyl pheno succinate, dodecyl diphenyl succinate, ditridecyl succinate, dioctyl sulfosuccinate, disodium laureth sulfosuccinate, diammonium 1-icosyl 2 sulfosuccinate, ammonium 1,4 didecyl sulfosuccinate, dihexyl sodium sulfosuccinate, sodium dinonyl sulfosuccinate, sodium lauryl sulfoacetate, salts thereof, and combinations thereof.

摘要： Mitigating or preventing corrosion of metal may be achieved in systems that are alkaline, such as carbon dioxide capture systems. The method may include adding an additive to a system wherein the system is at an alkaline pH; the system has both O2 and CO2 present; or the system is at an alkaline pH and has both O
2 and CO
2 present. The additive may be selected from the group consisting of: quaternary aromatic amines; quaternary alkyl substituted aromatic amines; and combinations thereof. The corrosion inhibiting properties of the additives may be increased by use of synergistic combinants. The abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b)-

摘要： The addition of strong neutralizing amines to react with free fatty acid in biodiesel fuels that may be left from some synthesis routes can lower the total acid number (TAN) of the biodiesel fuel. Surprisingly, the strong neutralizing amines do not interfere with the biodiesel fuel itself which may be primarily fatty acid methyl esters. These strong neutralizing amines may also improve the oxidative stability of biodiesel fuels.

摘要： It has been discovered that metal-containing components can be transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition which is a blend of polymers. The composition includes at least one diepoxide polymer, at least one polyol; and preferably at least one aromatic sulfonic acid. An aromatic solvent may be optionally included in the composition. The invention permits transfer of metal-containing components into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. The composition is particularly useful in treating crude oil emulsions, and in removing iron-containing components therefrom.

摘要： The present disclosure describes a method and system for estimating the onset of salt formation in an overhead fluid system. The method may include measuring parameters of a process stream by collecting data from one or more sensor arrays on an overhead line, such as from a distillation column, and then estimating the onset of salt formation corrosion using the data from the sensor arrays. The method may be implemented in real-time. The method may include transmitting data to monitoring facilities and/or sending instructions to alarms and/or regulators. Also described is a system for performing the method.

摘要： Multi-valent metals, such as iron, may be removed from crude oil by introducing at least one metal removal chemical to the crude oil before, during or after the crude oil is charged to a settling tank. After mixing the metal removal chemical with the crude oil, the crude oil is kept still or held quiescent for an effective period of time to allow the metal species to settle to the bottom of the tank. Oil having reduced metal content may be removed from the top of the tank and/or metal-rich oil may be drained from the bottom of the tank or both. The crude oil having reduced metal content will cause fewer problems downstream in the refinery.

摘要： It has been discovered that crosslinked polydimethylsiloxane (PDMS) resins are useful defoamers and antifoamers for hydrocarbon-containing liquids, such as delayed coker feedstocks and feedstocks to preflash and atmospheric towers. These PDMS resins are crosslinked with either alkyl polysilicate or siloxane. The crosslinked PDMS resins may be used alone or together with linear PDMS, and are typically blended with a carrier such as kerosene for easier handling. Importantly, the use of crosslinked branched PDMS resins permit less total amount of polysiloxanes to be used, which reduces the silicon carryover in coker products and reduces poisoning of downstream catalysts.
