High performance CO/HO displacement desorption sorbents and methods of making same

The disclosure generally relates to CCS sorbents, particularly for CO/HO displacement desorption process. The sorbent includes an aluminum oxide support and an alkali metal salt impregnated on the support, and a silicon modification of the sorbent to reduce water uptake by the sorbent and make it more hydrophobic. The silicon modification can be an organosilyl moiety added after the initial sorbent is complete, or a silica source added to the aluminum oxide structure, typically via impregnation. The sorbents demonstrate better HO/COratios. Compositions and methods of making are disclosed.

The disclosure generally relates to CCS sorbents, particularly for CO/HO displacement desorption process. The sorbents include an aluminum oxide support that includes two alkali metal salts impregnated on the support. The two alkali metals include a potassium metal salts and a second alkali metal salt which is not potassium. The second metal salt disrupts poisoning effects that degrade sorbent lifetime. The sorbents demonstrate improved COloadings and better HO/COratios, as well as improved stability. Compositions and methods of making are disclosed.

Mixed metal sorbents for CO/HO displacement desorption

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 CO, 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.

Separation of gases using reactive adsorbents and membranes

Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a power generation combustion reaction can be separated using a swing adsorption process so as to generate a high purity COstream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.

Integration of pressure swing adsorption with a power plant for COcapture/utilization and Nproduction

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.

Increasing scales, capacities, and/or efficiencies in swing adsorption processes with hydrocarbon gas feeds

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 COstream 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 COand recovers Hfrom 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 COto a cathode and the recovered Hto 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 COand H.

Hybrid high-temperature swing adsorption and fuel cell

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 CO, CO, N, HO, and H. CO may be converted to COand Hvia 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.

High purity nitrogen/hydrogen production from an exhaust stream

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 COpresent in syngas.

High temperature pressure swing adsorption for advanced sorption enhanced water gas shift

Methods and systems for detecting a material within a region of the Earth are provided. The region may be under a surface of earthen formation, ice, snow, or water. The method may be practiced in a variety of applications, for example in an arctic region to detect oil spills, leaks, or seepages. The methods and systems may include using at least one coil to transmit a radio frequency (RF) excitation signal into the region of the Earth; and receive any NMR response signals to determine the presence of the material of interest.

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.

Staged complementary PSA system for low energy fractionation of mixed fluid

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 COfrom the exhaust gas. An adsorption cycle of the first swing adsorption reactor is variable. An injection well injects the COadsorbed 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 CO. A second swing adsorption reactor purifies the produced hydrocarbons by adsorbing the produced COfrom the production well.

Dual integrated PSA for simultaneous power plant emission control and enhanced hydrocarbon recovery

Systems and methods for using pressure swing adsorption to separate and/or capture resulting emissions are provided. A stream of recycled exhaust gas is passed into a first swing adsorption reactor comprising a first adsorbent material which adsorbs CO. An enriched Nstream is recovered from a forward end of the first swing adsorption reactor. The pressure in the first swing adsorption reactor is reduced. The first swing adsorption reactor is purged with a portion of the first Nstream recovered from the first swing adsorption reactor. The first purge output is passed to a second swing adsorption reactor comprising a second adsorbent material which adsorbs CO. A second Nstream is recovered from the second swing adsorption reactor. The pressure in the second swing adsorption reactor is reduced. The second swing adsorption reactor is purged with a steam purge.
