Abstract: A system and process for upgrading a whole crude oil feed in an integrated ebullated-bed and hydrotreater is provided in which the whole crude oil is flashed into a flashed straight run distillates fraction and an atmospheric residue fraction. The atmospheric residue fraction is hydroprocessed in an ebullated-bed reaction zone, while the flashed straight run distillates fraction and the products fraction produced from the ebullated-bed reaction zone are hydrotreated in a fixed-bed reaction zone. Distillates from the hydrotreater and the unconverted residue fraction from the ebullated-bed reaction zone can be combined to produce an upgraded synthetic crude oil.
Abstract: A process for the production of middle distillates from a paraffinic feedstock produced by Fischer-Tropsch synthesis comprising a limited content of molecules containing at least one oxygen atom. In the process, the feedstock is subjected to at least one hydrocracking/hydroisomerization stage in the presence of a hydrogen stream also containing a limited atomic oxygen content.

Abstract: Methods and fuel processing apparatuses for upgrading a pyrolysis oil stream and a hydrocarbon stream are provided herein. In an embodiment, a method for upgrading a pyrolysis oil stream and a hydrocarbon stream includes providing a pyrolysis oil stream and providing a hydrocarbon stream separate from the pyrolysis oil stream. The pyrolysis oil stream and the hydrocarbon stream are mixed in a mixing zone and in the absence of a particulate cracking catalyst. The pyrolysis oil stream and the hydrocarbon stream are introduced in a substantially common direction into the mixing zone to form a mixture of the pyrolysis oil stream and the hydrocarbon stream. The mixture of the pyrolysis oil stream and the hydrocarbon stream are catalytically cracked in the presence of the particulate cracking catalyst.
Abstract: Embodiments of apparatuses and methods for treating mercaptans are provided. In one example, an apparatus comprises a vessel capable of receiving a feed stream that comprises liquid hydrocarbons and the mercaptans. The vessel comprises an extraction section that is capable of extracting a portion of the mercaptans from the feed stream to form a mercaptan-reduced, liquid hydrocarbon-containing stream. A catalyst bed section is capable of contacting the mercaptan-reduced, liquid hydrocarbon-containing stream with a catalyst in the presence of oxygen (O2) and caustic at reaction conditions effective to oxidize a remaining portion of the mercaptans and form a sweetened liquid hydrocarbon-containing stream.

Abstract: The present invention is directed to a method for making a catalyst for hydroprocessing a carbonaceous feedstock under hydroprocessing conditions, and the use of that catalyst. More particularly, the present invention is directed to methods for inhibiting rapid decomposition of ammonium nitrate during calcination of the catalyst following metal impregnation, wherein ammonium nitrate is formed when a nitrate-containing composition and an ammonium-containing component is used in the deposition of metal onto the catalyst.
Abstract: The physical and chemical properties of heavy and extra-heavy crudes are improved by a procedure that uses a homogeneous type catalyst and involves the stages: 1. separation and removal of the water fraction that is contained in the hydrocarbons, 2. catalyst injection and activation of the reaction system, 3. elimination of gaseous hydrocarbons and recovery of the partial pressure of hydrogen at different times, 4. reaction and 5. recovery of distillated products.

Abstract: A bitumen stream is upgraded by heating to near-critical or super-critical conditions in the stream. The bitumen stream may be from a water-based extraction process, an in situ bitumen recovery process, or a solvent-based bitumen extraction process. To achieve an appropriate feed stream composition, water and/or clay may be added. The clay offers a catalytic effect. To achieve an appropriate feed stream composition, water may alternatively be removed.
Abstract: An apparatus and method are provided for processing hydrocarbon feeds. The method enhances the conversion of hydrocarbon feeds into ethylene. In particular, the present techniques expose feed containing hydrocarbons to high-severity operating conditions in a pyrolysis reactor and separate the reactor product from the reactor into a first product having hydrogen and a second product including ?90 mole percent of the acetylene in the reactor product. Then, the second product is reacted with a catalyst in a converter to form ethylene.

Abstract: A system for desalting a crude oil stream includes an elongated, vertically oriented vessel that has an interior piping structure arranged concentric to the vessel. The piping structure, which may have more than one level, has a plurality of spray nozzles oriented at a downward angle for atomizing wash water into a downward flowing crude oil stream. The spray nozzles may be located on a same side or opposite sides of the piping structure. Where multiple levels are used, the number of spray nozzles on each level may be the same as or different than the number of spray nozzles on other levels. The pressure drop through each spray nozzle is preferably no greater than 300 psi and the nozzles preferably deliver a dilution water droplet preferably no larger than 300 microns in diameter. A mixing valve, static mixer, or both can be placed downstream of the vessel.
