摘要： A process for cracking hydrocarbon feedstock containing resid comprising: heating the feedstock, mixing the heated feedstock with a fluid and/or a primary dilution steam stream to form a mixture, flashing the mixture to form a vapor phase and a liquid phase which collect as bottoms and removing the liquid phase, separating and cracking the vapor phase, and cooling the product effluent, wherein the bottoms are maintained under conditions to effect at least partial visbreaking. The visbroken bottoms may be steam stripped to recover the visbroken molecules while avoiding entrainment of the bottoms liquid. An apparatus for carrying out the process is also provided.

摘要： The invention relates to a method for processing asphaltene-containing feed to a pyrolysis furnace by raising the final boiling point of the feed/steam mixture to the pyrolysis furnace to ensure fouling occurs lower in the convection section where the mixture of air and steam can burn off fouling deposits during decoking operations. The final boiling point of the feed stream is increased by adding a heavy essentially asphaltene-free high boiling point hydrocarbon to the feed stream before the feed stream enters the convection section of the pyrolysis furnace, whereby said fouling occurs lower in the convection section.

摘要： A feedstream comprising tar is feed to a solvent deasphalter wherein it is contacted with a deasphalting solvent or fluid to produce a composition comprising a mixture or slurry of solvent containing a soluble portion of the tar, and a heavy tar fraction comprising the insoluble portion of the tar. These fractions may be separated in the deasphalter apparatus, such as by gravity settling wherein the heavy tar fraction is taken off as bottoms, and the solvent-soluble fraction taken as overflow or overheads with the solvent. The overflow or overheads is sent to a solvent recovery unit, such as a distillation apparatus, wherein solvent is recovered as overheads and a deasphalted tar fraction is taken off as a sidestream or bottoms. The solvent or a portion thereof, recovered as overheads, may be then be recycled to the solvent deasphalter, or in a preferred embodiment, at least a portion of the solvent is steam cracked to produce a product comprising light olefins.

摘要： Underground storage caverns are used for the bulk storage of hydrocarbon liquids, such as crude oil and gases, such as natural gas. The cavern is accessed through a bore hole which has casing and, for some bore holes, internal tubing with an annulus between the casing and tubing. The upper end of the cavern has a roughly cylindrical region termed the chimney. In order to check it for physical integrity, it is necessary to measure the profile of the chimney. This is also referred to as conducting a survey of the cavern. The cavern typically has hydrocarbon liquid above brine up to the surface. An inert gas can be injected above the hydrocarbon liquid to form an interface. The profile is conducted by driving the gas/liquid interface downward with gas pressure to a reference level determined by sequentially transmitting acoustic pulses to locate the reference level. Gas is injected to increase the pressure by a predetermined value and thereby drive down the interface by a known distance. The volume of the gas injected is used together with the known distance to determine a profile of the chimney. The process of injection of gas to increase the pressure by the predetermined value and measurement of the volume is repeated sequentially to determine the chimney profile at progressively lower regions, thereby producing an extended profile of the chimney.

摘要： Underground storage caverns are used for the bulk storage of hydrocarbon liquids, such as crude oil and gases. The caverns are typically formed in salt formations by dissolving the salt and removing it with a flow of water. The cavern is accessed through a bore hole which has casing and internal tubing with an annulus between the casing and tubing. Some cavern bore holes may have casing, but no tubing. The cavern typically has hydrocarbon liquid above brine with an inert gas above the hydrocarbon liquid. In order to use the cavern, and periodically check it for physical integrity, it is necessary to test the cavern to determine if there is leakage from the cavern or the bore hole. The interface of the hydrocarbon liquid and overriding gas is moved downward by injecting gas into the annulus. Acoustic pulses are sent down the annulus through the gas to determine when the interface is located just below the end of the casing in the top of the cavern chimney (a reference level) by examining the return reflection pulse from the interface for a polarity inversion. When this is detected, a measured volume of gas is injected into the annulus. After a waiting period, the gas is released from the annulus and measured until the interface is detected by acoustic pulses to again be at the reference level. The volumes of injected gas and released gas are compared to determine if there has been leakage from the cavern. Alternative, the interface can be driven by gas pressure from the surface down to the casing bottom and back to the surface with gas volumes detecting leakage.
