A gas separation process in which the thermal storage of the heat in the gas is desired as well as the gas separation. This invention outlines a novel process and system whereby the thermal storage efficiency can be vastly increased by matching the gas sorption fronts and the thermal fronts to cause thermal front sharpening. The gas separation process and system include an adsorption vessel having an adsorbent in an amount of 10-40% and a thermal storage component in an amount of 50-90% by volume.

A carbon dioxide recovery system, which is configured to separate and recover carbon dioxide from a carbon dioxide containing gas, includes an adsorption unit that includes an adsorbent material that is configured to adsorb and desorb the carbon dioxide. The adsorbent material is configured to radiate heat in response to adsorption of the carbon dioxide and is configured to absorb the heat in response to desorption of the carbon dioxide. The adsorption unit is one of a plurality of adsorption units, and adjacent two adsorption units among the plurality of adsorption units contact with each other. When one of the adjacent two adsorption units adsorbs the carbon dioxide, another one of the adjacent two adsorption units desorbs the carbon dioxide.

Various embodiments disclosed herein include a system and method for processing an exhaust gas. The system comprises a regenerative thermal oxidizer (RTO), a bypass flow module in parallel with the RTO, and a mixing module disposed downstream of the RTO; wherein the RTO is configured to oxidize a first part of the exhaust gas and produce a hot tail gas and deliver a predetermined amount of the hot tail gas outside of the RTO, and the mixing module is configured to receive the predetermined amount of the hot tail gas; and wherein the bypass flow module is configured to receive and bypass a second part of the exhaust gas around the RTO into the mixing module; and wherein the second part of the exhaust gas absorbs sufficient heat from the predetermined amount of the hot tail gas in the mixing module for oxidizing and decomposing an organic compound therein.

A display device of a vehicle on which a CO.sub.2 recovery device is mounted, the CO.sub.2 recovery device through which gas circulates recovering carbon dioxide from the gas, the display device includes: a controller configured to control the vehicle, the controller including a recovery state determination unit configured to determine a recovery amount or a recovery state of the carbon dioxide recovered by the CO.sub.2 recovery device and an image data creation unit configured to create image data corresponding to the recovery amount or the recovery state detected by the recovery state determination unit; and a display screen configured to receive the image data and display an image corresponding to the image data, wherein the image data and the image vary depending on the recovery amount or the recovery state.

An osmotic transport apparatus includes a heat conducting chamber having an inner wall, a heat absorption end and a heat dissipation end, an osmotic membrane extending substantially longitudinally along an inner wall of the heat conducting chamber from the heat absorption end to the heat dissipation end, a liquid salt solution disposed in the osmotic membrane, and an inner vapor cavity so that when heat is applied to the heat absorption end, vapor is expelled from the osmotic membrane at the heat absorption end, is condensed on the osmotic membrane at the heat dissipation end, and is drawn into the osmotic membrane at the heat dissipation end for passive pumping transport back to the heat absorption end as more condensate is drawn through the osmotic membrane.

A process and a plant for decreasing the concentration of NOx nitrogen oxides in the residual gas in the preparation of nitric acid, where the temperature of the residual gas is regulated by means of a temperature regulating apparatus during shutdown and/or start-up of the plant, with the residual gas being conveyed in a circuit and here flowing through the temperature regulating apparatus and the residual gas purification plant so that colorless shutdown and/or start-up of the plant is made possible.

Disclosed herein is a power-to-water (P2W) battery and its use for converting atmospheric water vapor into water by surplus renewable energy. The P2W battery includes, a thermal energy storage (TES) unit made of high-storage-density media for storing heat; a hygroscopic solution container consists of an inner container made of a conduction material for receiving the TES unit therein, a water vapor permeable membrane disposed outside and around the inner container, a hygroscopic solution disposed between a space formed between the inner container and the water vapor permeable membrane; and a condenser disposed downstream and coupled to the hygroscopic solution container; wherein the hygroscopic solution is capable of absorbing the atmospheric water vapor, which is released by heat stored within the TES unit when the TES unit is received in the inner container; and the atmospheric water vapor released from the hygroscopic solution is condensed into water by the condenser.

A system for reducing carbon dioxide emissions from a flue gas is provided. The system includes a carbonator, and a calciner. The carbonator receives the flue gas and lean sorbent particles such that the lean sorbent particles absorb gaseous carbon dioxide from the flue gas and become loaded sorbent particles. The calciner includes a drum that defines a cavity having a first opening and a second opening. The first opening is fluidly connected to the carbonator such that the loaded sorbent particles flow into the cavity from the carbonator. The drum rotates such that at least some of the loaded sorbent particles are mixed with heat-transferring particles so as to release the absorbed gaseous carbon dioxide and exit the drum via the second opening as lean sorbent particles.
