  • Patent number: 10814288
    Abstract: Gas separation modules and methods for use including an integrated adsorbent and membrane. In certain refining applications, it is paramount to obtain high purity product gases. Adsorbent beds are effective at removing certain contaminants, such as CO2, from gas streams containing product and contaminant constituents to form a product-rich stream. The integrated membrane permits a further separation of products from any unadsorbed contaminant to produce a high purity product, such as hydrogen, stream. The gas separation modules described herein include stacked, radial, and spiral arrangements. Each modules includes a configuration of feed and cross-flow channels for the collection of contaminant gases and/or high purity product gases.

  • Patent number: 10449479
    Abstract: An adsorption module and associated processes for conducting advanced separations processes such as sorption enhanced water-gas shift (SEWGS). The adsorption module contains at least one angled baffle to create at least two tapered adsorbent beds within the adsorption module. The taper is such that the adsorbent beds' cross-sections within the adsorption module decrease in the direction of feed flow, thereby taking advantage of increased product purity and process efficiency provided by tapered adsorption beds.

  • Patent number: 10439242
    Abstract: Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a molten carbonate fuel cell power generation reaction can be separated by using a swing adsorption process so as to generate a high purity CO2 stream while reducing or minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. A high temperature adsorption reactor adsorbs the CO2 and recovers H2 from an exhaust gas of a first molten carbonate fuel cell at a high temperature and at a low pressure. The reactor passes along the adsorbed CO2 to a cathode and the recovered H2 to an anode of a second molten carbonate fuel cell for further power generation. This can allow for improved energy recovery while also generating high purity streams of CO2 and H2.

  • Publication number: 20190300801
    Abstract: Systems and methods are provided for performing multistage naphtha reforming with intermediate separation of aromatics using a swing adsorption process. Use of a swing adsorption process can allow aromatics to be selectively removed from the intermediate reforming effluent while reducing or minimizing the energy costs for cooling and subsequent reheating of the intermediate reforming effluent. The resulting aromatics-rich stream generated from swing adsorption can have a substantially higher aromatics content than an aromatics-rich stream generated by conventional separation methods during multi-stage naphtha reforming. In some aspects, selective thermal purging (either hot or cold) can be used to further facilitate adsorption or desorption of components by the adsorbent in the swing adsorption vessel.

  • Patent number: 10350538
    Abstract: In various aspects, methods are provided for hydrogen production while reducing and/or mitigating emissions during various refinery processes that produce syngas, such as power generation. Syngas can be effectively separated to generate high purity carbon dioxide and hydrogen streams, while reducing and/or minimizing the energy required for the separation, and without needing to reduce the temperature of the flue gas. In various aspects, the operating conditions, such as high temperature, mixed metal oxide adsorbents, and cycle variations, for a pressure swing adsorption reactor can be selected to minimize energy penalties while still effectively capturing the CO2 present in syngas.

  • Patent number: 10350537
    Abstract: Methods are provided for the production of nitrogen, hydrogen, and carbon dioxide from an exhaust gas. Exhaust gas from combustion in a fuel rich (or reducing) atmosphere is primarily composed of CO2, CO, N2, H2O, and H2. CO may be converted to CO2 and H2 via the water gas shift reaction. Carbon dioxide may then be effectively separated from nitrogen and hydrogen to produce a carbon dioxide stream and a nitrogen/hydrogen stream. The nitrogen/hydrogen stream may then be effectively separated to produce a high purity nitrogen stream and a high purity hydrogen stream. The process may be done in any order, such as separating the nitrogen first or the carbon dioxide first.

  • Publication number: 20190107590
    Abstract: Provided are systems, methods, and apparatus for using nuclear magnetic resonance (NMR) to detect a first material in the presence of a second material within a region of the Earth and within a static magnetic field (such as Earth's magnetic field). These inventions are uniquely suited to detect NMR signals from materials remotely located from a measurement device (e.g., below ice with the device above the ice). They are further useful in detecting first material having relatively short spin-lattice (T1) relaxation time in the presence of second material having longer T1 relaxation time (and therefore slower response to applied magnetic fields). Two pre-polarization currents are used to create pre-polarization magnetic fields stronger than the static magnetic field, each applied over a period of time between the first material's T1 relaxation time and the second material's T1 relaxation time, enabling different ways to null the NMR signal from the second material.

  • Patent number: 10143960
    Abstract: A staged complementary pressure swing adsorption system and method for low energy fractionation of a mixed fluid. Two beds in a four-column PSA system are selective for component A, and another two columns are selective for component B. The cycle creates an intermittent A and B product, using the purge effluent from the complementary product fed at an intermediate pressure. This intermittent product is used as purge gas for low-pressure purged elsewhere in the cycle using appropriate storage tanks. The use of an intermediate pressure in this cycle enables continuous production of purified component A and B without the use of compressors. Columns may also be configured to enable pressure to equalize between complementary columns.

  • Patent number: 10125641
    Abstract: Systems and methods are provided for combined cycle power generation and enhanced hydrocarbon production where emission gases during power generation are separated by adsorption and applied to facilitate extraction of hydrocarbons from a reservoir. A power generation plant passes exhaust gas to a first swing adsorption reactor. The first swing adsorption reactor adsorbs the CO2 from the exhaust gas. An adsorption cycle of the first swing adsorption reactor is variable. An injection well injects the CO2 adsorbed by the first swing adsorption reactor in a hydrocarbon reservoir. A production well that is in communication with the injection well produces a mixture of hydrocarbons and CO2. A second swing adsorption reactor purifies the produced hydrocarbons by adsorbing the produced CO2 from the production well.
