  • Patent number: 10927309
    Abstract: Methods for conserving the use of fresh wash water in crude oil desalting are described. A crude oil stream including salt mixes with a wash water stream to form an emulsion. The emulsion flows to a desalter, and the wash water coalesces to reform the wash water stream and to transfer at least a portion of the salt from the crude oil stream to the wash water stream. The crude oil stream with reduced salt content separates from the wash water stream. The effluent, which includes the wash water stream, flows from the desalter to a processing unit. The effluent is processed to reduce a concentration of salt in the effluent to be substantially equal to or less than a concentration of salt in the wash water stream. At least a portion of the processed effluent mixes with the crude oil stream before the emulsion flows to the desalter.

  • Patent number: 10918966
    Abstract: A system and method to vaporize a process or feed water stream does so in a liquid pool zone of a vessel as the stream comes into contact with a heating medium that is less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is vaporized, any solids present in the process stream come out of the process stream and move into the heating medium. These solids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized process stream can be further condensed. Any heat recovered can be used to pre-heat the process stream or used in the pump around loop's heater in case of mechanical vapor recovery.

  • Patent number: 10864456
    Abstract: A system and method to partially vaporize a process or feed water stream does so in a liquid pool zone of a vessel as the stream comes into contact with a heating medium that is less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is partially vaporized, any solids present in the process stream together with the unvaporized process or feed water stream move into the heating medium. These solids and unvaporized liquids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized process stream can be further condensed. Any heat recovered can be used to pre-heat the process stream or in the pump-around loop's heater in case of mechanical vapor recovery.

  • Patent number: 10865350
    Abstract: A process and apparatus provides alternative hydrotreating reactor trains for hydrotreating a hydrocarbon stream. One hydrotreating reactor train is smaller than the other and the smaller train comes on stream to allow replacement or regeneration of catalyst in the larger train. A sulfide system also sulfides the catalyst volume in the reactor train that is off stream to prepare it for renewed hydroprocessing of feed when back on stream. The process and apparatus can be used to keep hydroprocessing reactors on stream to continuously provide feed to an FCC unit which has a longer period before shut down.
