摘要:
An apparatus and method are provided for processing hydrocarbon feeds. The method enhances the conversion of hydrocarbon feeds into conversion products, such as ethylene and propylene. In particular, the present techniques combine a first hydrocarbon feed with a second hydrocarbon feed and a hydrogen (H2) containing stream to manage the hydrogen content of the feed provided to a pyrolysis reactor. The mixture is then exposed to high-severity operating conditions in a pyrolysis reactor and further processing into desired olefins.
摘要:
The invention concerns integration of hydroprocessing and steam cracking. A feed comprising crude or resid-containing fraction thereof is severely hydrotreated and passed to a steam cracker to obtain an olefins product.
摘要:
This invention relates to a process and system for cracking hydrocarbon feedstock containing vacuum resid comprising: (a) subjecting a vacuum resid to a first thermal conversion in a thermal conversion reactor (such as delayed coker, fluid coker, Flexicoker™, visbreaker and catalytic hydrovisbreaker) where at least 30 wt % of the vacuum resid is converted to material boiling below 1050° F. (566° C.); (b) introducing said thermally converted resid to a vapor/liquid separator, said separator being integrated into a steam cracking furnace, to form a vapor phase and liquid phase; (c) passing said vapor phase to the radiant furnace in said steam cracking furnace; and (d) recovering at least 30 wt % olefins from the material exiting the radiant furnace (based upon the weight of the total hydrocarbon material exiting the radiant furnace).

A process, apparatus and system for forming light olefins, the process including heating a resid-containing hydrocarbon feedstock containing at least 10 ppmw of metals to vaporize at least 90 wt. % of said hydrocarbon feedstock; separating in a knockout drum a hydrocarbon vapor portion having less than 10 ppmw metals from a non-vaporized resid-containing portion; and feeding said hydrocarbon vapor to a catalytic cracking process to form light olefins.
摘要:
This invention relates to a process of producing an upgraded product stream from steam cracker tar feedstream suitable for use in refinery or chemical plant processes or for utilization in fuel oil sales or blending. This process utilizes an ultrafiltration process for separating the steam cracker tar constituents resulting in a high recovery, low-energy process with improved separation and product properties.
摘要:
In one aspect, the inventive process comprises a process for pyrolyzing a hydrocarbon feedstock containing nonvolatiles in a regenerative pyrolysis reactor system. The process comprises: (a) heating the nonvolatile-containing hydrocarbon feedstock upstream of a regenerative pyrolysis reactor system to a temperature sufficient to form a vapor phase that is essentially free of nonvolatiles and a liquid phase containing the nonvolatiles; (b) separating said vapor phase from said liquid phase; (c) feeding the separated vapor phase and methane to the pyrolysis reactor system; and (d) converting the methane and separated vapor phase in said pyrolysis reactor system to form a pyrolysis product. In another aspect, the invention includes a separation process that feeds multiple pyrolysis reactors.
