Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport. In still other aspects, the systems and methods can allow for reduced incorporation of external streams into the final product for transport while still satisfying one or more target properties.

Apparatus and process for upgrading heavy hydrocarbons

This disclosure relates to methods for reducing COemissions from a fluid catalytic cracking process by providing a chemical looping system comprising a regenerator and reducer reactor, an oxidizer reactor, and a combustor reactor, and by sequestering the carbon dioxide of a COand HO stream. Also, this disclosure relates to methods for reducing COemissions from a fluid catalytic cracking process by partially oxidizing catalyst coke particles in a fluid catalytic cracking regenerator reactor to produce synthesis gas, and by providing a chemical looping system comprising a reducer reactor, an oxidizer reactor, and a combustor reactor.

System to convert coke in fluid catalytic cracking process by utilizing metal oxides with in-situ COcapture

Systems and methods are provided for expanding the operating envelope for an FCC reaction system while also reducing or minimizing the net environmental COemissions associated with the FCC reaction system and/or the resulting FCC products. In some aspects, reducing or minimizing net environmental COemissions can be achieved during processing of unconventional feeds, such as feeds that are traditionally viewed as having insufficient tendency to coke in order to maintain heat balance within an FCC reaction system. In other aspects, this can correspond to expanding the production of diesel within an FCC reaction system by modifying the reaction conditions in a manner that can cause a reaction system to fall out of heat balance (relative to the heat needed to maintain a target operating temperature) even when using conventional feeds.

Slurry hydroconversion process for upgrading heavy hydrocarbons

Provided is a process capable of converting the cokes on spent catalysts in a fluid catalytic cracking (FCC) process into synthesis gas. The produced synthesis gas contains high concentrations of CO and Hand may be utilized in many downstream applications such as syngas fermentation for alcohol production, hydrogen production and synthesis of chemical intermediates. A reducer/regenerator reactor for a fluid catalytic process comprising a chemical looping system to produce synthesis gas is also described.

Integrated methods and systems are disclosed for the production of dimethyl ether. The method may include reforming natural gas to syngas in a first reactor; contacting the syngas produced in the first reactor with a catalyst system in a second reactor to produce dimethyl ether and carbon dioxide; and supplying steam as a cofeed to at least one of the first reactor and the second reactor in an amount sufficient to achieve a Mvalue of 1.4 to 1.8 or to improve the hydrocarbon or oxygenate selectivity.

Adsorbent materials comprising a ZIF material and cross-linked polymer are provided herein. Methods of separating organic compounds from an aqueous solution or a non-aqueous solution and biofuel production processes using the adsorbent material are also provided herein.

The invention relates to improved bitumen recovery processes and systems. One process provides for operation of a bitumen froth treatment plant at optimum shear rates in the feed pipe carrying the bitumen froth to the froth settling unit. Another process provides for optimizing the design of a bitumen froth treatment plant by optimizing the diameter of the feed pipe to impart an optimum shear rate to the bitumen froth mixture and further optimizing the volume of the feed pipe to impart an optimum residence time for the bitumen froth stream in the feed pipe. An optimal plant design is also disclosed, the plant including optimal diameter and volume of the feed pipe.

Optimizing feed mixer performance in a paraffinic froth treatment process

The disclosure relates to improved bitumen recovery processes and systems. In particular, the disclosure teaches processes and systems for recovering heavy crude oil while avoiding fouling of equipment by recycling at least a portion of a product bitumen from a solvent recovery unit for mixing with an overhead bitumen stream that may be a diluted bitumen stream containing solvent and bitumen. The overhead bitumen stream is a near-incompatible stream and the stream of mixed overhead bitumen stream and the treated bitumen stream is a compatible stream that will not foul equipment upon heating.

Fouling reduction in a paraffinic froth treatment process by solubility control

The invention relates to improved bitumen recovery processes and systems. The process may include providing a bitumen froth feed stream, separating the stream in a froth separation unit to produce a diluted bitumen stream, treating the diluted bitumen stream in an electrostatic desalter to produce a treated bitumen stream, and separating the treated bitumen stream into a solvent recycle stream and a bitumen product stream. The system may include a combined AC/DC desalter with a control unit for optimizing the treatment process to produce a product bitumen stream using less solvent and smaller separators than conventional bitumen froth treatment plants and processes.

Optimizing heavy oil recovery processes using electrostatic desalters

A distillation tower for use in a petrochemical or petroleum operation effects liquid and vapor separation by using centrifugal force applied to the feed introduced into a ring from a tangential inlet. The feed is separated into a liquid component that flows into the bottoms section of the tower and a vapor component that flows upwardly through the core of the ring to a wash zone in the tower. De-entrainment devices are provided in the core so that the vapor swirling upwardly impacts the devices and any remaining entrained liquid is separated from the vapor. As a result, overflash with decreased resid can be collected from the wash zone and used as feed suitable for a fluid catalytic cracking operation, for example.
