  • Patent number: 10773203
    Abstract: A xenon capture system that reduces the concentration of xenon in a carrier gas is disclosed. An example xenon capture system includes a carrier gas with a first concentration of xenon that flows through an intake into a chamber. Within the chamber is a reaction area that has at least one peripheral sidewall. The reaction area operates at a predetermined temperature, flow rate, and low pressure. Within the reaction area is at least one xenon capture mechanism that is at least partially formed of a transition metal. When the carrier gas is exposed to the xenon capture mechanism, the xenon capture mechanism adsorbs xenon from the carrier gas. The carrier gas, with a second concentration of xenon, exits the chamber through the exhaust outlet.

  • Patent number: 10703690
    Abstract: The present invention relates to a method of preparing butadiene and a device for preparing the same. According to the present invention, when butadiene is prepared by oxidative dehydrogenation of butene, unlike conventional methods, in which nitrogen is used as a diluent gas and an absorption method is used to separate butadiene from reaction products, butane is used as a diluent gas and a condensation method, in which butadiene is liquefied and separated from reaction products using a low-temperature refrigerant or cooling water, is used. In addition, an absorption method of recovering all hydrocarbons from an upper stream generated in a condensation process is used, so that loss of hydrocarbons is minimized. Therefore, the method and device of the present invention may provide high-purity butadiene while reducing raw material costs, production costs, and energy consumption, thereby improving economic efficiency of processes.

    Abstract: The invention refers to a device and a process for extracting water from the environment. The device comprises a means for capturing water from the environment by means of a liquid desiccant, an extraction chamber, a first duct through which liquid desiccant with water flows from the capture means to the extraction chamber, a second duct through which liquid desiccant flows from the extraction chamber to the capture means, a reservoir for depositing extracted water, a third duct through which water flows from the extraction chamber to the reservoir, a vacuum generator whose suction point and discharge point are operationally connected to the reservoir in order to suction the gas present in the reservoir and transfer gas into the reservoir, and a control device that controls the vacuum generator. The operation of the vacuum generator creates a pressure and temperature gradient that leads to evaporation of the water in the extraction chamber.

  • Patent number: 10662126
    Abstract: Methods of simultaneously converting butanes and methanol to olefins over Ti-containing zeolite catalysts are described. The exothermicity of the alcohols to olefins reaction is matched by endothermicity of dehydrogenation reaction of butane(s) to light olefins resulting in a thermo-neutral process. The Ti-containing zeolites provide excellent selectivity to light olefins as well as exceptionally high hydrothermal stability. The coupled reaction may advantageously be conducted in a staged reactor with methanol/DME conversion zones alternating with zones for butane(s) dehydrogenation. The resulting light olefins can then be reacted with iso-butane to produce high-octane alkylate. The net result is a highly efficient and low cost method for converting methanol and butanes to alkylate.
