Publication number: 20230053229Abstract: Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into light and heavy fractions utilizing convection heat from heaters used in steam cracking. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize either an ebullated bed reactor with extrudate catalysts or a slurry hydrocracking reactor using a homogeneous catalyst system, such as a molybdenum based catalysts which may optionally be promoted with nickel. Products from the upgrading operations can be finished olefins and/or aromatics, or, for heavier products from the upgrading operations, may be used as feed to the steam cracker.Type: ApplicationFiled: October 31, 2022Publication date: February 16, 2023Applicant: LUMMUS TECHNOLOGY LLCInventors: Ujjal K.

Patent number: 11566190Abstract: Integrated processes and systems for the production of distillate hydrocarbons and coke. The process may include feeding a hydrocarbon feedstock, comprising a residuum hydrocarbon fraction, to a residue hydrocracking reactor system to convert hydrocarbons therein, producing a hydrocracked effluent. The hydrocracked effluent may then be fed to a separation system, separating the hydrocracked effluent into one or more distillate hydrocarbon fractions and a vacuum residue fraction. The vacuum residue fraction may be fed to a coker system, converting the vacuum residue fraction into a coke product and a coker vapor effluent, recovering the coke product, and feeding the coker vapor effluent to the separation system. The one or more distillate hydrocarbon fractions are hydroprocessed to produce a hydroprocessed effluent, and the hydroprocessed effluent is separated into product distillate hydrocarbon fractions.Type: GrantFiled: July 26, 2021Date of Patent: January 31, 2023Assignee: LUMMUS TECHNOLOGY LLCInventors: Suresh B.

Patent number: 11565985Abstract: Systems and processes herein improve the conversion of propylene to ethylene via metathesis. On a mass basis, embodiments herein may be used to convert greater than 40% propylene, on a mass basis, to ethylene, such as 43% to 75%, on a mass basis. In one aspect, processes for the conversion of propylene to ethylene herein may include introducing a propylene feed stream to a metathesis reactor, and contacting the propylene with a metathesis catalyst in the metathesis reactor to convert the propylene to ethylene and 2-butene. An effluent from the metathesis reactor may be recovered, the effluent including ethylene, 2-butene, and unconverted propylene. The effluent may then be separated in a fractionation system to recover an ethylene fraction, a propylene fraction, a c4 fraction, and a C5+ fraction. The propylene fraction and the C4 fraction may then be fed to the metathesis reactor to produce additional ethylene.Type: GrantFiled: November 20, 2020Date of Patent: January 31, 2023Assignee: LUMMUS TECHNOLOGY LLCInventor: Bala Ramachandran
