Abstract: Embodiments of the present invention are generally related to a system and method to remove hydrogen sulfide from sour water and sour oil. In particular, hydrogen sulfide is removed from sour water and sour oil without the need for special chemicals, such as catalyst chemicals, scavenger chemicals, hydrocarbon sources, or a large scale facility. The system and method in the present invention is particularly useful in exploratory oil and gas fields, where large facilities to remove hydrogen sulfide may be inaccessible. The present invention addresses the need for safe and cost effective transport of the deadly neurotoxin. Particular embodiments involve a system and method that can be executed both on a small and large scale to sweeten sour water and sour oil.

Abstract: A method for upgrading a hydrocarbon feed is disclosed. The method may be carried out in a pyrolysis furnace that may have at least two coils and at least two thermal zones. The method may include two operating or run modes that may be repeated in a cycle. In one run, upgrading may be carried out in one coil while decoking may be carried out in the other coil. After a predetermined amount of time, the streams of the two coils may be switched for a second run, such that decoking may be carried out in the coil in which upgrading was done in the first run and upgrading may be carried out in the coil in which decoking was done in the first run. The first and the second run are cyclically repeated one after the other.
Abstract: The present invention relates to a process for the treatment of refinery purge streams, containing a hydrocarbon component in slurry phase having a boiling point higher than or equal to 140° C., characterized by the presence of quantities of asphaltenes higher than or equal to 5% by weight and characterized by the presence of a solid content higher than or equal to 5% by weight. The process provides that said purge be mixed with a suitable fluxing agent according to appropriate ratios and under certain conditions, forming a suspension with a content higher than or equal to 10% by weight of compounds having a boiling point TbP lower than or equal to 350° C. After mixing, the suspension is sent to a liquid/solid separation step which operates under suitable conditions, separating a solid phase containing a residual organic component and a solid component, called cake, and a liquid phase containing residual solids. The solid phase obtained is cooled to below 60° C.
Abstract: One or more processes for stabilizing a hydrocarbon stream. An unstabilized hydrocarbon stream comprising C5+ hydrocarbons and including some butane, propane and ethane, may be passed to a first separation zone. The first separation zone has an increased operating pressure so that a residue gas stream recovered from the first separation zone requires minimal compression for further processing. A bottoms stream form the first separation zone is passed to a second, lower pressure separation zone which provides an NGL stream and a C5+ liquid hydrocarbon stream that is stabilized.
Abstract: Methods for reducing potential pollutants in carbonaceous materials such as coal, lignites and the like prior to utilization such as by combustion, the invention in preferred embodiments processes such materials by resonance disintegration including inter alia subjection to rapid pressure increases and decreases to reduce the materials to particle sizes of a preferable mean value of approximately fifty microns or less. Pollutants such as sulfur, mercury and other heavy metals bound in a mineral fraction and micronized by such processing can then removed by classification techniques based on physical differences between a micronized carbonaceous fraction and the mineral fraction. Combustion of the micronized carbonaceous fraction substantially free of the mineral fraction results in emissions having reduced levels of sulfur, mercury and other toxic substances.

Abstract: The present invention relates to delayed coking of heavy petroleum residue producing petroleum coke and lighter hydrocarbon products. The invented process utilize a pre-cracking reactor and a reactor furnace for mild thermal cracking of the feedstock and an intermediate separator, before being subjected to higher severity thermal cracking treatment in a coker furnace and a coking drums, resulting in reduction in overall coke yield.
Abstract: A membrane unit is able to recover hydrogen from a resid waste gas stream. Two membrane units provide even greater hydrogen recovery. The membrane separation is performed at conditions that allow the pressure of the recovered hydrogen to enter into a second stage of compression, saving the expense of the first stage of compression.

Abstract: Processes and apparatuses are disclosed for treating a naphtha stream from a FCC unit comprising passing the naphtha stream to a naphtha splitter column to provide a light naphtha stream and a heavy naphtha stream. The light naphtha stream is reacted in a mercaptan oxidation reactor to provide a demercaptanized naphtha stream. The demercaptanized naphtha stream is stripped in a light stripper column to provide a treated light naphtha stream and a bottoms stream.
Abstract: Processes and systems for upgrading resid hydrocarbon feeds are disclosed. The process system may operate in two different operating modes, maximum conversion and maximum quality effluent. The process system may be reversibly transitioned between the different operating modes. The system has the ability to reversibly transition between the two modes without shutting down the system or losing production.

Abstract: Slurry hydrocracking processes are described. The methods include hydrotreating a heavy residual hydrocarbon feed in a hydrotreating zone under residual hydrotreating conditions to form a hydrotreated effluent. The hydrotreated effluent is separated in an first separator to form an overhead vapor stream and a bottoms stream. The bottoms stream is hydrocracked in a slurry hydrocracking zone under slurry hydrocracking conditions. The effluent from the slurry hydrocracking zone is fractionated in a fractionation zone into at least two streams. Slurry hydrocracking apparatus is also described.
Abstract: Settling unconverted pitch from a SHC reactor effluent before fractionation improves efficiency of fractionation of slurry hydrocracked products. The recycle of soft pitch to the SHC reactor results in improved reactor operation by avoiding the recycle of lighter products which vaporize in the reactor to occupy reactor space and the recycle of hard pitch which will not convert. The settling step facilitated by mixing with a solvent can achieve a separation between soft pitch and hard pitch not achievable in a fractionation column.
