The concepts described herein provide for a system, apparatus and/or method for fuel vapor capture on-vehicle for evaporative emission control. This includes a device for capturing fuel vapor on-vehicle that includes a canister device having a first port that is fluidly coupled to a head space portion of a fuel tank. The canister device defines a chamber that is fluidly coupled in series between the first port and a second port. A first Metal Organic Framework (MOF) material is disposed in the chamber to adsorb fuel vapor constituents.

Systems, devices and methods for submarine CO.sub.2 scrubbing are disclosed. The system may comprise an assembly including a sorbent, a scrubbing inlet configured to receive a first airflow during an adsorption mode. The first airflow may comprise air received from a cabin of a submarine. The assembly may be configured to flow the first airflow over and/or through the sorbent during the adsorption mode such that the sorbent removes a portion of CO.sub.2 entrained in the first airflow. The system may also include a scrubbing outlet configured to expel the scrubbed first airflow from the assembly into the cabin. The system may include an outside air inlet configured to receive a second airflow comprising outside air during a regeneration mode. The system may include a regeneration air outlet in configured to expel the second airflow after the second airflow has flowed over and/or through the sorbent during the regeneration mode.

A system for integrated removal of multiple pollutants includes an economizer, an air preheater, an electrostatic precipitator, a flue gas cooler and a low-temperature adsorber; the economizer has a shell side inlet for feeding boiler flue gas, a tube side inlet for feeding boiler feedwater, and a shell side outlet connected to a tube side inlet of the air preheater; the air preheater has a shell side inlet for introducing boiler intake air, and a tube side outlet connected to the electrostatic precipitator; the electrostatic precipitator has a dust discharge port at a bottom thereof and a flue gas outlet connected to the flue gas cooler; the flue gas cooler has a condensate outlet at a bottom thereof and a cold flue gas outlet at a top thereof and connected to the low-temperature adsorber; and the low-temperature adsorber has a purified flue gas outlet at a tail thereof.

Disclosed is a process for the regeneration of an adsorber. For the regeneration a liquid stream (S2) is applied which is obtained by hydrogenation of a stream (S1) comprising at least one alkane and least one olefin. The stream (S2) comprises one alkane and a reduced amount of at least one olefin compared to the amount in the stream (S1). Then the stream (S2) is converted from the liquid into the gaseous phase and the adsorber is regenerated by contact with the gaseous stream (S2).

A method for controlling an adsorption dryer for the treatment of compressed gas includes vessels therein and a valve arrangement for selectively feeding upstream compressed gas to, and outputting dried downstream compressed gas from, the vessels. Compressed gas is fed to at least one of the vessels in a process phase for drying the compressed gas through liquid adsorption by the desiccant bed and removing the adsorbed liquid from the bed in the vessels in a regeneration phase. An ambient value occurring outside both the vessels and downstream compressed gas output is measured. Additional steps include determining a characteristic value based on the measured ambient value, matching the value to criteria associated with stored regeneration phase parameter settings, determining a regeneration phase parameter setting based on the matching of the value, and applying the parameter setting to the regeneration phase for setting a parameter of the regeneration phase.

Disclosed is an improved process for recovering condensable components from a gas stream, in particular, hydrocarbons from a gas stream such as natural gas. The present process uses solid adsorbent media to remove said hydrocarbons wherein the adsorbent media is regenerated in a continuous fashion in a heated continuous counter-current regeneration system, wherein said heated regenerated adsorbent media is cooled prior to reuse.

Disclosed are processes, apparatuses, and systems for Direct Air Carbon Capture (DACC). An example process involves using a stream of exhaust air flowing from an air cooled heat exchanger to drive a DACC unit. Another example process involves conveying waste heat recovered from an industrial source to the DACC unit. The waste heat may be used to remove captured CO2 from a capture device of the DACC unit and/or for regeneration of the capture device.

A rechargeable battery assembly for a vehicle has a housing and at least one metal-air rechargeable battery arranged in the housing. A filter device is arranged in the housing and conditions the inlet air of the at least one metal-air rechargeable battery such that the inlet air exhibits a predetermined air humidity.

A flow deflecting device is provided that deflects the inlet air in the housing such that the filter device can be regenerated by waste heat of the at least one metal-air rechargeable battery.

The present invention relates to a dehumidification system and method and, in particular, to a system and method for controlling the humidity of air in a process or location using a desiccant-coated fluid-air heat exchanger. The desiccant material adsorbs water at or above ambient temperatures during an adsorption cycle, and the resultant air stream is of a reduced humidity compared with the humidity of the supply air. The desiccant material may then be dried during a regeneration cycle through addition of heating fluid through the heat exchanger, driving water back into the vapour state with addition of latent energy of vaporization. The desiccant material may be cooled, during the adsorption cycle, through addition of cooling fluid through the heat exchanger to maintain the temperature within a range sufficient for water vapour to be removed from the stream of air.

Industrial waste derived adsorbents were obtained by pyrolysis of sewage sludge, metal sludge, waste oil sludge and tobacco waste in some combination. The materials were used as media to remove hydrogen sulfide at room temperature in the presence of moisture. The initial and exhausted adsorbents after the breakthrough tests were characterized using sorption of nitrogen, thermal analysis, XRD, ICP, and surface pH measurements. Mixing tobacco and sludges result in a strong synergy enhancing the catalytic properties of adsorbents. During pyrolysis new mineral phases are formed as a result of solid state reaction between the components of the sludges. High temperature of pyrolysis is beneficial for the adsorbents due to the enhanced activation of carbonaceous phase and chemical stabilization of inorganic phase. Samples obtained at low temperature are sensitive to water, which deactivates their catalytic centers.
