A process for operating a reforming system by operating a reforming section containing a plurality of reactors, wherein each of the plurality of reactors containing a reforming catalyst capable of catalyzing the conversion of at least a portion of the hydrocarbons in a treated hydrocarbon stream into a reactor effluent comprising aromatic hydrocarbons, and operating a sulfur guard bed (SGB) to remove sulfur and sulfur-containing hydrocarbons from a hydrocarbon feed to provide the treated hydrocarbon stream, where the SGB contains at least a layer of a SGB catalyst comprising the same catalyst as the reforming catalyst, and where each reactor of the plurality of reactors within the reforming section may be operated at a higher operating temperature than an operating temperature of the SGB. A system for carrying out the process is also provided.

Provided is a carbon dioxide recovery system including: an absorption tower; a regeneration tower that takes in an absorbing solution that has absorbed carbon dioxide at the absorption tower, and separates the carbon dioxide from the absorbing solution using regenerated steam to regenerate the absorbing solution; first supply piping that supplies the absorbing solution regenerated in the regeneration tower to the absorption tower; a reclaimer that takes in part of the absorbing solution regenerated in the regeneration tower to remove degraded material and supplies the absorbing solution from which the degraded material has been removed to the regeneration tower or the first supply piping; an in-line viscometer that measures a viscosity of the absorbing solution flowing through the first supply piping; and a controller that controls an amount of the absorbing solution processed by the reclaimer based on the viscosity measured by the in-line viscometer.

A carbon dioxide recovery system that recovers carbon dioxide from a hybrid vehicle traveling in a CO.sub.2 recovery area including a CO.sub.2 recovery road in which a stationary CO.sub.2 recovery device collecting and recovering carbon dioxide from the atmosphere is provided acquires a residual charging capacity of the battery and position information of the hybrid vehicle and guides the hybrid vehicle such that the hybrid vehicle travels on the CO.sub.2 recovery road using a notification device when the residual charging capacity is equal to or less than a predetermined SOC threshold value while the hybrid vehicle is traveling in the CO.sub.2 recovery area.

A carbon dioxide (CO.sub.2) capture and utilization system captures CO.sub.2 from flue gas and utilizes the same to enhance algae or cyanobacteria growth. The system generally comprises a CO.sub.2 capture unit and a utilization unit that is in fluid communication with the CO.sub.2 capture unit. The CO.sub.2 capture unit includes a membrane CO.sub.2 absorber that captures CO.sub.2 from incoming flue gas to produce a CO.sub.2-rich solvent. The utilization unit processes the CO.sub.2-rich solvent to produce a product stream that includes CO.sub.2 and NH.sub.3 in a predetermined CO.sub.2:NH.sub.3 ratio. The product stream is delivered to a cultivation subsystem of the utilization of the unit including one or more species of algae or cyanobacteria. A method for capturing and utilizing CO.sub.2 is also provided herein.

An animal shed system includes an animal shed having an animal shed floor with a first and a second surface spaced apart, such that the floor has a thickness different from zero, and multiple flow holes extending from the first to the second surface; a reservoir situated under the animal shed floor, wherein the flow holes open up to the reservoir, and the flow holes allow a fluid flow from the animal shed to the reservoir; a floor opening in the animal shed floor to allow manure to be dumped in the reservoir; an air extraction device for extracting air underneath the floor, out of the reservoir; and a device extending from the floor opening into the reservoir, wherein the device is configured to prevent an airflow from the animal shed to the reservoir through the floor opening when in use.

Generating methane by adding hydrogen to CO.sub.2 in exhaust gas discharged a from cement production facility or CO.sub.2 that is separated and recovered from the exhaust gas, and using the methane as an alternative fuel to fossil fuel such as coal, petroleum, natural gas and the like, by methanation of CO.sub.2 in the exhaust gas from the cement production facility that includes exhaust gas originated from lime stone not from the fossil oil and effectively utilizing it, it is possible to reduce usage of the fossil fuel, suppress CO.sub.2 originated from energy, and improve an effect of reducing greenhouse gas.

A solvent system for the removal of acid gases from mixed gas streams is provided. Also provided is a process for removing acid gases from mixed gas streams using the disclosed solvent systems. The solvent systems may be utilized within a gas processing system.

Capture of hydrogen sulfide from a gas mixture may be accomplished using an aqueous solution comprising an amine. Certain sterically hindered amines may selectively form a reaction product with hydrogen sulfide under kinetically controlled contacting conditions and afford a light phase and a heavy phase above a critical solution temperature, wherein the hydrogen sulfide may be present in either phase. Upon separation of the light phase from the heavy phase, processing of one of the phases may take place to remove hydrogen sulfide therefrom. Recycling of the amine to an absorber tower may then take place to promote capture of additional hydrogen sulfide.
