Publication number: 20220306944Abstract: A process that catalytically converts olefinic (Alkenes, typically liquid at standard temperature and pressure) material in thermally cracked streams to meet olefin content specifications for crude oil transport pipelines. A thermally cracked stream or portion of a thermally cracked stream is selectively reacted to reduce the olefin content within a reactor operating at specific, controlled conditions in the presence of a catalyst and the absence of supplemental hydrogen. The process catalyst is comprised of a blend of select catalyzing metals supported on an alumina, silica or shape selective zeolite substrate together with appropriate pore acidic components.Type: ApplicationFiled: June 13, 2022Publication date: September 29, 2022Inventors: TOM CORSCADDEN, DARIUS RAMESAT, FRANK DAVID GUFFEY, SHUNLAN LIU, GREG DIDUCH

Patent number: 10421917Abstract: Non-condensable gas is used as an alternate to steam at hydrocarbon processing facilities removing any steam requirements thereby reducing greenhouse gas emissions, and improving profitability through capital and operating cost reductions. The non-condensable gas serves at least two functions sequentially in heavy hydrocarbon processing; firstly, providing the non-condensable gas as a stripping medium to evolve lighter hydrocarbons from the heavy hydrocarbon feedstock followed by secondly directing the same non-condensable gas and any evolved non-condensable gas at operating conditions for use as at least one of heat through combustion or power through electricity generation.Type: GrantFiled: November 22, 2017Date of Patent: September 24, 2019Assignee: MEG ENERGY CORP.Inventors: Tom Corscadden, Frank David Guffey, Greg Diduch, Jim Kearns, Darius Remesat

Patent number: 10280373Abstract: An apparatus and process is provided for improved asphaltene separation from heavy hydrocarbon or bitumen with low process complexity through mass transfer using solvent and counter-current flows, with three sections: an upper DAO/solid-asphaltene separation zone, a middle solvent mixing and segregation zone, and a bottom clarification zone. Solvent mixed with heavy hydrocarbon forms a process feed introduced to the process vessel's upper zone and exposed to counter-current solvent removing DAO from solid asphaltene particles in the feed, the particles fall through the middle zone and are mixed with introduced solvent, which introduced solvent segregates DAO-rich solution in the upper zone (for extraction from that zone) from solvent-rich mixtures in the middle mixing and lower clarification zones. Solvent flows and precipitate movement are controlled to optimize mass transfer in process, resulting in high DAO recovery and dry, solid asphaltene product.Type: GrantFiled: April 20, 2018Date of Patent: May 7, 2019Assignee: MEG ENERGY CORP.Inventors: Tom Corscadden, Jim Kearns, Greg Diduch, Damien Hocking, Darius Remesat

Patent number: 9944864Abstract: A process for producing pipeline-ready or refinery-ready feedstock from heavy hydrocarbons using a high-performance solvent extraction process with high local solvent-to-process fluid ratios yet maintaining low overall solvent-to-process fluid ratios, by first performing mild thermal cracking on the heavy hydrocarbons and then separating asphaltene-rich fractions from a resulting thermally affected fluid so that the high solvent-to-oil ratio portion of the process acts only on those asphaltene-rich fractions, and producing a dry, solid asphaltene as an end-product.Type: GrantFiled: October 23, 2015Date of Patent: April 17, 2018Assignee: MEG ENERGY CORP.Inventors: Tom Corscadden, Greg Diduch, Damien Hocking, Darius Remesat, Jim Kearns

Patent number: 9890337Abstract: The invention provides improved apparatus and method for producing a pipeline-ready or refinery-ready feedstock from heavy, high asphaltene crude, comprising a pre-heater for pre-heating a process fluid to a design temperature at or near the operating temperature of a reactor; moving the process fluid into the reactor for conversion of the process fluid by controlled application of heat to the process fluid in the reactor so that the process fluid maintains a substantially homogenous temperature to produce a stream of thermally affected asphaltene-rich fractions, and a stream of vapor. The stream of vapor is separated into two further streams: of non-condensable vapor, and of light liquid hydrocarbons. The thermally affected asphaltene-rich fraction is deasphalted using a solvent extraction process into streams of heavy deasphalted oil liquid, and concentrated asphaltene, respectively.Type: GrantFiled: September 26, 2016Date of Patent: February 13, 2018Assignee: MEG ENERGY CORP.Inventors: Tom Corscadden, Jim Kearns, Greg Diduch, Damien Hocking, Darius Remesat
