The invention relates to improved methods of desalting hydrocarbon feeds using a separator with a stacked disk centrifuge to separate an emulsified oil and water rag layer. This method is effective for desalting heavy, high ionic, and non-traditional crude oils.

Methods and apparatus for separating particulates from a fluid are provided. The apparatus can include a separation section having at least one wall, a first end, a second end, and an inner metal surface exposed to an internal volume of the separation section. The apparatus can also include a fluid discharge outlet in fluid communication with the internal volume at the first end. The apparatus can also include a particulate discharge outlet in fluid communication with the internal volume at the second end. The apparatus can also include an inlet in fluid communication with the internal volume. The inlet can be disposed intermediate the first end and the second end.

A gas-solids reaction system with termination devices to connect a riser with one or more separation devices. The termination devices have a radius of curvature that is at least 1.0 times as great as the diameter of the conduit forming the termination device. The termination devices can be openly or closely coupled to the separation devices.

A method for separating and recovering ultrafine particulate solid material from a suspension or slurry of the solid material and a hydrocarbon liquid by precipitation or flocculation of a heavy fraction of the hydrocarbon liquid with an effective amount of a precipitation or flocculation agent such that the precipitated heavy fraction encapsulates the particulate solid material. The method further comprises coking the precipitated heavy fraction and grinding the coked product to an ultrafine size.

The present invention provides a process for purifying coal tar through a centrifugation method. The process is characterized in that a viscosity of the centrifugated and separated coal tar is 30-100 mpa.s. According to the present invention, the viscosity of the coal tar is set to 30-100 mpa.s, and the viscosity is further preferably 50-100 mpa.s so as to effectively improve removing efficiency of QI particles in the coal tar.

A method of removing sulfur from sour oil by subjecting sour oil having a first sulfur content to high shear in the presence of at least one desulfurizing agent to produce a high shear treated stream, wherein the at least one desulfurizing agent is selected from the group consisting of bases and inorganic salts, and separating both a sulfur-rich product and a sweetened oil product from the high shear-treated stream, wherein the sulfur-rich product comprises elemental sulfur and wherein the sweetened oil product has a second sulfur content that is less than the first sulfur content. A system for reducing the sulfur content of sour oil via at least one high shear device comprising at least one rotor and at least one complementarily-shaped stator, and at least one separation device configured to separate a sulfur-rich product and sweetened oil from the high shear-treated stream.

A system and method for enhancing separation of a denser phase liquid from a lighter phase liquid within a multiphase stream. In one example, a cyclonic coalescer has a tubular housing and a plurality of coaxial flow chambers extending in the axial direction of the housing. A swirling element is associated with each of the plurality of coaxial flow chambers. The swirling elements are constructed and arranged to impart a tangential velocity of the stream flowing through the associated flow chamber.

The improved methods relate to desalting hydrocarbon feeds using a separator with a stacked disk centrifuge to separate an emulsified oil and water rag layer. This method is effective for desalting heavy, high ionic, and non-traditional crude oils.

The present invention relates to a method for separating catalyst fines from an oil stream comprising the steps of; separating catalyst fines from an inlet oil stream in a centrifugal separator to generate a stream of purified oil; obtaining an NMR response signal from an NMR apparatus related to the amount of catalyst fines in the purified oil stream and / or the inlet oil stream and initiating the addition of or increasing the amount of separation aid to the inlet oil stream when the NMR response signal indicates an increased amount of catalyst fines in the purified oil stream and / or the inlet oil stream, such as to increase the performance of separating catalyst fines from the oil stream.

The invention discloses a treating method for waste gas containing sulfur and hydrocarbons. The method comprises the following steps that: crude diesel or crude kerosene enters a rotating packed bed for devolatilization pretreatment; a material discharged from the liquid phase outlet of the rotating packed bed enters absorption equipment as an absorbent and contacts and reacts with waste gas containing sulfur and hydrocarbons, and hydrocarbons in the waste gas are recovered; waste gas discharged from the absorption equipment enters an alkali liquor absorption device for removal of sulfur-containing compounds in the waste gas, and a rich absorption solvent discharged from the absorption equipment directly enters a hydrogenation device; and waste gas discharged from the alkali liquor absorption device meets national standard and is discharged. The treating method for the waste gas containing sulfur and hydrocarbons provided by the invention adopts the rotating packed bed for pretreatment of the crude diesel or crude kerosene so as to remove foreign matters like hydrogen sulfide and volatile components in the crude diesel or crude kerosene, thereby preventing the waste gas from producing secondary pollution; and the method has the advantages of simple process, economical performance and reasonability and is applicable to absorption treating process for the waste gas containing sulfur and hydrocarbons.
