Patent number: 11465951Abstract: Systems and methods for producing dicyclopentadiene via thermal dimerization of cyclopentadiene. The feed stream comprising cyclopentadiene is flowed through four shell and tube heat exchangers in series. Each of the shell and tube heat exchangers comprise a shell and one or more tubes disposed in the shell. The feed stream is flowed in the tubes while the heat transfer medium is flowed in the shell to absorb the exothermic heat released by the dimerization of cyclopentadiene in the tubes. In this way, the temperature in the tubes is controlled at a level where the conversion rate of cyclopentadiene is above 99% and the occurrence of runaway reaction is substantially prevented.Type: GrantFiled: December 9, 2019Date of Patent: October 11, 2022Assignee: SABIC GLOBAL TECHNOLOGIES B.V.Inventors: Mohamed Sabri Abdelghani, Ernesto Uehara

Patent number: 11319498Abstract: Methods and systems for producing light olefins are disclosed. A feedstock comprising crude oil is distilled to produce a plurality of streams including a naphtha stream and a vacuum residue stream. The naphtha is fed to a steam cracking unit to produce light olefins, C4 hydrocarbons, pyrolysis gasoline and pyrolysis oil. The vacuum residue stream is hydrocracked to produce additional naphtha and heavy unconverted oil. The heavy unconverted oil and the pyrolysis oil from steam cracking unit can be deasphalted to produce deasphalted oil and pitch product. The deasphalted oil can be further hydrocracked to produce naphtha. The pitch product can be gasified to produce synthesis gas, which is further used to produce methanol. The methanol can be used to react with isobutylene of the C4 hydrocarbon stream from steam cracker to produce methyl tert-butyl ether (MTBE).Type: GrantFiled: December 3, 2019Date of Patent: May 3, 2022Assignees: SABIC GLOBAL TECHNOLOGIES B.V., SAUDI ARABIAN OIL COMPANYInventors: Nicolas Goyheneix, Hatem Belfadhel, Jurgen Kleibergen, Vinod Ramaseshan, Timothy Abbott, Mohamed Sabri Abdelghani
