摘要： An adsorbent vessel for removing contaminants from a feed gas upstream from a cryogenic distillation process using pressure swing adsorption, temperature swing adsorption, or thermal-pressure swing adsorption. The adsorbent vessel having an adsorbent bed comprised of multiple layers of adsorbent material, including two layers of adsorbent material that selective adsorbs carbon dioxide. Each of the two layers is formed from an adsorbent material having a different capacity for adsorbing carbon dioxide.

摘要： The invention relates to a process for fueling of vehicle tanks with compressed hydrogen comprising splitting ammonia into hydrogen and nitrogen in an ammonia cracking unit, compressing the hydrogen from the ammonia cracking unit, and dispensing the compressed hydrogen to the vehicle tanks in a hydrogen fueling unit comprising one or more dispensing units, wherein chilled ammonia is used to cool the compressed hydrogen before being dispensed to the vehicle tanks by heat exchange between the compressed hydrogen and the chilled ammonia so that the chilled ammonia is heated, and transferring the heated ammonia to the ammonia cracking unit.

摘要： A radial adsorber can be configured to facilitate utilization of different layers of material. The radial adsorber, system using at least one radial adsorber, and methods of utilizing embodiments of the radial adsorber can help permit improved efficient operation of fluid purification processing while also being configured to minimize, if not fully avoid, being susceptible to the effect of fluidization.

摘要： A method of constructing a coil wound heat exchange module and transporting and installing the coil wound heat exchange module at a plant site, such as an natural gas liquefaction plant. A module frame is constructed and attached to a heat exchanger shell prior to telescoping of a coil wound mandrel into the shell. The module frame includes a lug and two saddles that remain attached to the shell throughout the process and when the heat exchanger is operated. The lug and saddles are constructed and located to stabilize the shell during construction, telescoping and transport (when in a horizontal orientation), and when the shell is installed at the plant site (in a vertical orientation). The lugs and saddles are adapted to allow for thermal expansion and contraction of the shell when it is transitioned from ambient to operating temperature and vice versa.

摘要： A coil-wound heat exchanger with mixed refrigerant shell side cooling that is adapted to reduce radial temperature maldistribution by providing tube sheets at one end of a warm bundle that are each connected to tube sheets in a single circumferential zone and are in fluid flow communication with a control valve. Tube sheets at the other end of the warm bundle are each connected to tube sheets in a single radial section and in multiple circumferential zones. A temperature sensor is provided in each circumferential zone. When a temperature difference is detected, one or more of the control valves is adjusted to reduce the temperature difference.

摘要： An apparatus and method for cooling a gas stream is provided comprising at least one heat exchanger in which a gas stream is cooled against a cooling liquid, whereby the cooling liquid temperature increases from a first temperature to a second temperature, at least one air cooler for cooling the cooling liquid after passing though the at least one heat exchanger, surface area of the at least one air cooler being designed to decrease temperature of the cooling liquid to the first temperature; a pump; and conduits to form a closed-circuit for the cooling liquid to pass continuously through the at least one heat exchanger and the at least one air cooler. The ratio of surface area of the at least one air cooler to the surface area of the at least one heat exchanger is optionally 12 or lower, and the difference of temperature between the second temperature and first temperature being greater than 15° C.

摘要： A method of melting a charge in a double-pass tilt rotary furnace having a door, including operating a first burner at a first firing rate, the first burner being mounted in a lower portion of the door and producing a first flame having a length; operating a second burner at a second firing rate, the second burner being mounted in an upper portion of the door and producing a second flame having a length, the second flame being distal from the charge relative to the first flame; in an initial phase when the solids in the charge impede the first flame, controlling the second firing rate to be greater than the first firing rate; and in an later phase after melting of the solids in the charge sufficiently that the first flame is not impeded, controlling the first firing rate to be greater than the second firing rate.
