  • Patent number: 10722861
    Abstract: Reactor systems for use with ionic liquid catalyst. The reactor systems include one or more stages, which include a reactor and a heat exchanger, and a separation zone. The reactor and the heat exchanger may have a vertical orientation. Additionally, a separation vessel may also include a vertical orientation. The heat exchanger may allow for linear flow of process fluid to control residence time.

  • Patent number: 10702798
    Abstract: A process for treating an ionic liquid containing waste stream is described. If there is a liquid waste stream, the liquid waste stream is introduced into a liquid treatment zone. The ionic liquid in the liquid waste stream is neutralized. The concentration of the ionic liquid in the liquid waste stream is determined, and the allowed concentration of the ionic liquid in the liquid waste stream is determined. The concentration of the ionic liquid in the neutralized liquid waste stream is reduced to the allowed concentration, and the liquid waste stream having the allowed concentration is released. If there is a vapor waste stream, the vapor waste stream is introduced into a vapor treatment zone. The vapor waste stream is treated to form a treated vapor waste stream, and the treated vapor waste stream is released to a plant vapor treatment zone.

  • Patent number: 10654033
    Abstract: A separation vessel for separating an effluent stream that comprises a mixture of hydrocarbons and ionic liquid. The separation vessels may be vertically orientated. Ionic liquid is utilized to remove entrained ionic liquid droplets form rising hydrocarbons within the separation zone. The ionic liquid may be provided with a stream of the ionic liquid from the separation vessel. The ionic liquid may be provided as a layer or travel counter-current to the hydrocarbons rising in the separation vessel.

  • Patent number: 10618858
    Abstract: A method of alkylating a hydrocarbon stream including: providing a feed stream that includes hydrocarbons and ionic liquid catalyst; passing the feed stream through a low efficiency mixer to create a mixed stream, whereby the low efficiency mixer creates droplets within the feed stream that are primarily within a predetermined size range; passing the mixed stream and an olefin stream into a reactor; performing an alkylation reaction within the reactor, thereby forming a reacted stream; and separating the reacted stream into a settled ionic liquid catalyst stream and a hydrocarbon stream through the use of at least one hydrocyclone.

  • Patent number: 10584079
    Abstract: An alkylation process and apparatus are described. The alkylation process includes pre-mixing a paraffin stream with an ionic liquid catalyst stream from a settler. The premixed paraffin and ionic liquid catalyst stream is mixed in a low-efficiency pump to form a paraffin and ionic liquid catalyst mixture. An olefin feed stream is introduced into a riser reactor. The paraffin and ionic liquid catalyst mixture is introduced into the riser reactor to form a reaction mixture comprising alkylate and the ionic liquid catalyst. The reaction mixture is separated in a settler into an ionic liquid catalyst stream and a hydrocarbon stream.

  • Patent number: 10384988
    Abstract: The present invention involves processes and equipment for handling chloride in an ionic liquid alkylation system. The processes involve not only breaking down the organic chloride to active HCl for ionic liquid activation, but also recovering HCl in the effluent downstream to maintain the HCl requirements while also reducing HCl emissions. This equipment may be used in conjunction with an isomerization reaction zone which is integrated into the ionic liquid alkylation process to further isomerize n-paraffins to isoparaffins for recycle to the alkylation reaction zone.

  • Publication number: 20170113979
    Abstract: An alkylation process system uses an ionic liquid as a catalyst which undergoes an interruption in normal operating condition. A method of maintaining the alkylation process system during the interruption of the normal operating condition requires maintaining a circulation of the ionic liquid through the alkylation process system without interruption.

  • Patent number: 9329106
    Abstract: Methods, apparatuses, and kits for collecting chemical samples are provided. In one embodiment, a method for collecting a sample of a chemical from a vessel includes connecting a sampling chamber and a removal chamber in fluid communication with the vessel and flowing a liquid phase of the chemical from the vessel through the sampling chamber and the removal chamber. The method isolates a first volume of the liquid phase in the sampling chamber and removes a second volume of the liquid phase from the removal chamber. Further, the method includes establishing fluid communication between the sampling chamber and the removal chamber and filling the removal chamber with a portion of the first volume to form a vapor phase of the chemical in the sampling chamber. Also, the method includes isolating the sample including the vapor phase and a remaining portion of the liquid phase in the sampling chamber.
