  • Patent number: 10259734
    Abstract: This invention presents an innovative de-scaling step to effectively eliminate scale obstacles in desalination plants to: (1) allow better performance ratio by either reducing steam load or increasing distillate production, and thus more efficient and cost effective plants; (2) reduce the enormous volumes of the total required seawater (recycle brine and returned cooling seawater) and reject brine; (3) eliminate the addition of scale inhibitors and frequent shut-downs to remove scale buildup; and (4) minimize reduction in heat transfer coefficients. This invention, as a result of the effective de-scaling step, also presents a new effective design for Multi-Stage Flash (MSF) desalination plants, which is based on what its coined a Brine-Forward (BF) concept. The BF-MSF concept is multi-boiling without supplying additional heat after the train's brine heater, and multi-concentration without supplying additional seawater after the first train of the plant.

  • Patent number: 10259765
    Abstract: Disclosed are novel processes for making cyclohexanone compositions, from a mixture comprising phenol, cyclohexanone, and cyclohexylbenzene. The process includes hydrogenation of a feed stream comprising phenol, cyclohexanone, and cyclohexylbenzene. The feed stream may be subjected to one or more pre-hydrogenation treatments, such as passing through one or more sorbents, addition of basic chemical agents, and/or addition of water, so as to improve catalyst activity, minimize undesired side reactions, and/or remove catalyst poisons from the feed stream. The feed stream may be provided to a hydrogenation reaction zone in the vapor phase, with periodic alterations to hydrogenation reaction conditions such that the feed is provided in mixed liquid and vapor phase in order to carry out liquid washing of a hydrogenation catalyst bed within the hydrogenation reaction zone.
