  • Patent number: 11460454
    Abstract: A method for monitoring, evaluating and controlling a cyclic chromatographic purification process that involves at least two adsorbers. According to the method, one step is monitoring of the chromatogram, including the measurement of at least one current concentration-proportional signal in the liquid. Another step is conducting an evaluation of the chromatogram, including a comparison of at least one of the current concentration-proportional signals measured in the monitoring step with a threshold value thereof. A further step is controlling the chromatographic purification process by adapting the termination of the currently running phase as a function of the comparison of the evaluation step and initiating the next phase. Finally, according to the method, the sequence of steps is carried out in given order at least twice.

  • Patent number: 11459515
    Abstract: Heavy hydrocarbon feedstocks including crude oil are upgraded under relatively low pressure conditions in an ebullated-bed hydroprocessing zone to remove the heteroatom containing hydrocarbons. Catalyst particles are regenerated/rejuvenated and recycled back to the ebullated-bed hydroprocessing reaction zone. The regeneration/rejuvenation is effective to restore catalytic activity while minimizing leaching of the active components(s).

  • Patent number: 11447704
    Abstract: A process, a system, and an apparatus for separation of an oxygenate from a stream is provided. More specifically, a stream comprising the oxygenate is introduced to a quench tower along with a caustic outlet stream comprising a metal salt. Contact between the oxygenate and the metal salt results in conversion of a portion of the oxygenate into a derivative salt. The derivative salt and unconverted oxygenate are condensed by quenching and substantially removed from the quench tower as an oxygenate outlet stream. The gaseous components of the stream, minus a substantial portion of the oxygenate, are removed from the quench tower as a quench outlet stream.

  • Patent number: 11420916
    Abstract: The present disclosure pertains to methods and systems for separating olefins from a mixture that includes olefins and non-olefins. The methods include associating the mixture with a support that is embedded with an ionic liquid and a metal ion. The ionic liquid prevents the substantial reduction of the metal ion by reducing agents while the metal ion mediates the transport of the olefin through the support by selectively and reversibly coupling with the olefin. In some embodiments, the support may be in the form of supported ionic liquid porous membranes, and the ionic liquid may be held within the pores of the support by capillary forces. In some embodiments, the support may be in the form of a composite, and the ionic liquid may be dispersed throughout the composite. In some embodiments, the metal ion may be dissolved in the ionic liquid and dispersed throughout the support.

  • Patent number: 11406958
    Abstract: The present disclosure relates generally processes and systems for converting a C2-C7 light alkanes feed to liquid transportation fuels or value-added chemicals. The feed is contacted with an aromatization catalyst at a temperature and pressure that selectively converts C4 and larger alkanes to an intermediate product comprising monocyclic aromatics and olefins. Following separation of the aromatics and C5+ hydrocarbons from the intermediate product, unconverted C2-C3 alkanes are thermally-cracked to produce olefins that are subsequently oligomerized to produce a liquid transportation fuel blend stock or value-added chemicals.

  • Patent number: 11396630
    Abstract: A method of producing olefins by catalytic cracking of hydrocarbons is disclosed. The method may include catalytic cracking hydrocarbons in a feed stream that includes the hydrocarbons and the dry gas diluent. The catalytic cracking may be carried out in a process using a train of fixed bed reactors while one or more other trains of fixed bed reactors are being regenerated or are on standby after being regenerated. When the train of fixed bed reactors being used needs regenerating, it is taken out of service and the one or more other trains of fixed bed reactors put in service to carry out the catalytic cracking process. Dry gas instead of steam may be used to reduce the partial pressure of hydrocarbons.
