Disclosed are process and system for making an asphalt product and an olefin product from an asphaltenes-rich feed without using a vacuum distillation column. The feed is first deep stripped in a first stripping column using a stripping vapor such as steam and/or a C2-C3 paraffins-rich stream to obtain a bottoms liquid effluent having a high cutpoint and an overheads effluent comprising gas oil, lighter hydrocarbons, and the stripping vapor. The high-boiling point bottoms liquids effluent, with optional additional separation and/or treatment, can be used as asphalt products. The overheads effluent, with optional additional separation, can be fed into a pyrolysis furnace cracker, where it is converted into a cracker product mixture comprising olefins, lighter hydrocarbons, hydrogen, and the like, which can be recovered in a products recovery subsystem.

Process and system for processing asphaltenes-rich feed

Processes, systems, and apparatus are provided for producing a compressed process gas comprising light olefin such as ethylene. The process utilizes a pyrolysis reactor to produce the process gas. A power generator utilizes a turbine operated based on an Allam cycle to produce shaft power for operating one or more compressors involved in processing of the process gas while producing a reduced or minimized amount of COthat is released as a low-pressure gas phase product. Examples of using the shaft power for processing of the process gas can include compressing the process gas a process gas compressor powered by the produced shaft power and cooling the process gas using a refrigeration compressor powered by the produced shaft power.

A method and apparatus for conversion of petroleum resid fluid through atomization and pyrolysis, including: generating a stream of atomized resid fluid; and delivering the stream to a plurality of cracking particles, wherein the cracking particles have a temperature from 700° C. to 1200° C. when the stream is delivered. Generating the stream of atomized resid fluid may include: delivering heated resid fluid to a nozzle; and delivering diluent fluid to the nozzle. A method and apparatus includes: a first multi-phase fluid application device configured to generate a first stream of atomized resid fluid; a port configured to guide a plurality of cracking particles to intersect the first stream; and a particle heating component configured to heat the cracking particles before the particles intersect the first stream.

Processes for converting an organic-material-containing feed comprising contacting the feed with a plurality of fluidized hot particles in a pyrolysis zone to product a first pyrolysis effluent, optionally contacting the first pyrolysis effluent with a quenching stream to impart additional pyrolysis of organic materials contained in the quenching stream, separating at least a portion of the particles and feeding them to a combustion zone where the particles are heated to an elevated temperature, optionally contacting the combustion zone effluent with a second organic-material-containing stream to produce, e.g., syngas, and feeding at least a portion of the heated particles to the pyrolysis zone.

Processes for converting organic material-containing feeds via pyrolysis

Processes are described for isomerizing one or more C-Calpha olefins to produce an isomerization mixture comprising one or more C-Cinternal olefins comprising contacting an olefinic feed comprising the one or more C-Calpha olefins with a catalyst under isomerization conditions, wherein the catalyst comprises a microporous crystalline aluminosilicate having an MWW framework. The resulting isomerization mixture typically exhibits a low pour point with maintained biodegradability properties as compared to the olefinic feed, and is particularly useful in drilling fluid and paper sizing compositions.

A catalyst and corresponding methods of using a catalyst are provided that can be beneficial for conversion of paraffins into a product stream enriched in aromatics and/or methane while reducing or minimizing the content of ethane in the product stream. Such catalysts and methods can be useful, for example, for processing a raw gas, associated gas, tail gas, natural gas, or other type of methane-containing feed stream to convert Chydrocarbons in the stream to heavier hydrocarbons and methane while reducing or minimizing content of ethane in the products from the conversion reaction. Such conversion can be useful for upgrading a methane-containing feed stream to have an energy content that is suitable for pipeline transport under one or more specifications for transport of natural gas. The catalyst and corresponding method can also be beneficial when used as a second stage catalyst in a configuration involving multiple conversion stages.

Systems and methods are provided for conversion of light paraffinic gases to form liquid products in a process performed in a fixed bed radial-flow reactor. The light paraffins can correspond to Cparaffins. Examples of liquid products that can be formed include C-Caromatics, such as benzene, toluene, and xylene. The fixed bed radial-flow reactor can allow for improved control over the reaction conditions for paraffin conversion in spite of the fixed bed nature of the reactor. This can allow the process to operate with improved efficiency while reducing or minimizing the complexity of operation relative to non-fixed bed reactor systems.
