An apparatus and method for flow management and CO-recovery from a COcontaining hydrocarbon flow stream, such as a post CO-stimulation flowback stream. The apparatus including a flow control zone, a gas separation zone, a pretreatment zone, and a CO-capture zone. The CO-capture zone is in fluid communication with the pretreatment zone to provide CO-capture from a pretreated flowback gas stream and output a captured CO-flow stream. The CO-capture zone includes a first CO-enricher and at least one additional COenricher disposed downstream of the first COenricher and in cascading relationship to provide a CO-rich permeate stream, the CO-capture zone further including at least one condenser to condense the enriched CO-stream and output the captured CO-flow stream.

Flow management and CO-recovery apparatus and method of use

Method includes recovering a stimulating fluid, which includes transferring working fluid having the stimulating fluid from an operating site () to a current temporary processing facility (TPF) () that is located remotely with respect to the operating site in the geographical region. After purifying the working fluid at the current TPF (), thereby providing the stimulating fluid, the stimulating fluid is transferred from the current TPF to an injection site () that is located remotely with respect to the current TPF and the operating site. The method also includes transporting fluid-handling equipment after a designated condition has been satisfied. The fluid-handling equipment is transported from the current TPF () to a new TPF (). The recovering of the stimulating fluid, the transferring of the stimulating fluid, and the transporting of the fluid-handling equipment is repeated a plurality of times. The current and new TPFs are at different locations within the geographical region.

Thermoelectric energy storage system and an associated method are disclosed. The thermoelectric energy storage system includes a first refrigeration system, a power system, a first thermal storage unit, and a second thermal storage unit. The first refrigeration system includes a first heat exchanger, a first compressor, a second heat exchanger, and a first expander. The first heat exchanger is disposed upstream relative to the first compressor. The power system includes a third heat exchanger, a second compressor, a fourth heat exchanger, a fifth heat exchanger, and a second expander. The third heat exchanger is disposed upstream relative to the fourth heat exchanger. The fifth heat exchanger is disposed downstream relative to the second expander. The first thermal storage unit is coupled to the first heat exchanger and the fifth heat exchanger. The second thermal storage unit is coupled to the first refrigeration system and the power system.

Thermoelectric energy storage system and an associated method thereof

The subject matter disclosed herein relates to a liquefaction system. Specifically, the present disclosure relates to systems and methods for condensing a pressurized gaseous working fluid, such as natural gas, using at least one turboexpander in combination with other cooling devices and techniques. In one embodiment, a turboexpander may be used in combination with a heat exchanger using vapor compression refrigeration to condense natural gas.

An apparatus and method for flow management and CO-recovery from a COcontaining hydrocarbon flow stream, such as a post CO-stimulation flowback stream. The apparatus including a flow control zone, a gas separation zone, a pretreatment zone, and a CO-capture zone. The CO-capture zone is in fluid communication with the pretreatment zone to provide CO-capture from a pretreated flowback gas stream and output a captured CO-flow stream. The CO-capture zone includes a flow splitter to direct a first portion of the pretreated flowback gas stream to a CO-enricher to provide an enriched CO-stream for mixing with a second portion of the pretreated flowback gas to form a mixed stream. The CO-capture zone further includes at least one condenser to output the captured CO-flow stream.

Flow management and CO2-recovery apparatus and method of use

An electrothermal energy storage and discharge system is provided including a charging cycle and a discharging cycle. The charging cycle includes a refrigeration unit and a thermal unit, and the discharging cycle includes a power unit. The refrigeration unit is driven by an excess electric power and is configured to generate a cold energy storage having a solid carbon dioxide. The thermal unit is driven by a thermal energy and is configured to generate a hot energy storage and/or provide a hot source. The power unit operates between the cold energy storage and at least one of the hot energy storage and hot source so as to retrieve the energy by producing a high pressure carbon dioxide and a hot supercritical carbon dioxide, and generating an electric energy using the hot supercritical carbon dioxide.

Electrothermal energy storage system and an associated method thereof

A system and method are provided for boosting overall performance of a fuel cell while simultaneously separating a nearly pure stream of COfor sequestration or for use in generating electrical power to further increase overall efficiency of the process. The system and method employ a heat exchanger system configured to generate a stream of fuel that is returned to the inlet of the fuel cell anode with a higher molar concentration of carbon monoxide (CO) and hydrogen (H) fuel than was initially present in the fuel cell anode outlet.

A hybrid multichannel porous structure for processing between two fluid streams of different compositions includes a housing and one or more structures disposed within the cavity of the housing in a shell and tube configuration. Each structure includes a body made of a porous, inorganic material and a plurality of channels for processing an optional sweep stream. Each channel is coated with a membrane layer. A feed stream introduced into the housing is in direct contact with the structures such that a gas selectively permeates through the body and into the channels. The gas combines with the sweep stream to form a permeate that exits from each channel. The remaining feed stream forms a retentate that exits from the housing. The feed stream may consist of syngas containing hydrogen gas and the sweep stream may contain nitrogen gas. A power plant that incorporates the hybrid structure is disclosed.

Hybrid multichannel porous structure for hydrogen separation

The present invention is directed to a method for reducing PCB concentration in an electrical induction apparatus containing a dielectric fluid with greater than 500 ppm PCB to a level of less than about 50 ppm PCB. Dielectric fluid containing greater than 500 ppm PCB is drained from an electrical induction apparatus, and the drained apparatus then is filled with tetrachloroethylene as a first interim dielectric fluid. The apparatus is then electrically operated with the first interim dielectric fluid so as to attain about an equilibrium PCB concentration in the first fluid. The first interim dielectric fluid then is drained from the apparatus and replaced with fresh tetrachloroethylene as a second interim dielectric fluid. The apparatus then is electrically operated with the second interim dielectric fluid so as to attain about an equilibrium PCB concentration in the second fluid. The second interim dielectric fluid then is drained from the apparatus and replaced with a silicone fluid as a permanent dielectric fluid. The apparatus filled with permanent dielectric fluid is electrically operated and the permanent dielectric fluid is filtered through a carbon filter, so as to attain a PCB concentration in the permanent fluid of less than about 50 ppm.
