Captured data center waste-heat is used as the input energy for carbon capture plant. Energy in the form of waste-heat is first captured from servers and other apparatus within the data center and optionally directed as the input to a heat-pump before being directed to the input of carbon capture plant, enabling carbon capture using a data centers waste-heat. Also disclosed are systems and apparatus for data center operators or cloud services to offer carbon negative or carbon neutral services to their customers. Cloud customers are offered options to select a carbon negative or carbon neutral service, the cloud operator storing their choice and then operating or managing carbon capture services to meet their requests.

The present invention relates to the CO.sub.2 and O.sub.2 remover. The CO.sub.2 and O.sub.2 remover comprises 65 to 85 weight percent (wt. %) of a nickel oxide (NiO), 5 to 20 wt. % of a magnesium oxide (MgO), wherein the weight ratio of the nickel oxide and the magnesium oxide (NiO/MgO) is 4 to 11, and wherein the wt. % is based on the weight of the CO.sub.2 and O.sub.2 remover.

A method for producing a nano-porous membrane with one or up to four graphene layers, pores in the membrane having an average pore size in the range of 0.2-50 or 0.3-10 nm, wherein the method involves the following steps: a) generation of a contiguous, essentially non-porous membrane with one or up to four graphene layers; b) distributed point wise defect creation in the non-porous membrane with one or up to four graphene layers by way of irradiation; c) generation and successive growth of the pores at the defects generated in step b) by thermal annealing in the gas phase, e.g. under 02 at a temperature in the range of 250° C. to less than 400° C.

Systems and methods for separating a biogas or other gaseous material into its constituent parts, including solid methane and carbon dioxide, using liquid nitrogen in a processing chamber. The individual parts may be extracted from the processing chamber. Separation and extraction can be performed on a mobile processing plant.

There is provided a nitrogen rejection unit for extracting nitrogen and carbon dioxide from a flue gas, the system comprising: a first container for holding a first volume of the flue gas at a first pressure and a first temperature that is below or equal to the condensation temperature of the carbon dioxide and greater than the condensation temperature of nitrogen; an outlet for removing the carbon dioxide as a liquid from the first container; means for transporting gaseous nitrogen from the first container to a second container and means for cooling the nitrogen such that the second container contains nitrogen at a second temperature that is below or equal to its condensation temperature such that at least some of the nitrogen in the second container is in liquid form; and means for guiding the liquid nitrogen from the second container through or around the first container to cool the material within the first container to the first temperature. There is also provided a system for capturing carbon dioxide in a flue gas, a method for extracting nitrogen from a flue gas, and a method for capturing carbon dioxide in a flue gas.

An emissions clean-up process is provided to remove detrimental exhaust gases from a fossil fuel power plant and to produce and/or reclaim various useful commercial byproducts. The process includes mixing a blended liquid solution with a solubilizer in a mixing tank to create a chemical reaction therein to produce an ionic solid and an alkaline liquid solution. By mixing various blended solutions with desired solubilizers, alkaline liquids are produced which may be chemically combined to create other byproducts or sold commercially. Likewise, the alkaline liquids may be passed through a wet scrubber to create a byproduct that when chemically mixed with an acid creates desired byproducts. Other byproducts such as a sodium bicarbonate liquid solution exits the wet scrubber and is sold or used in the subject process to produce various other byproducts.

A method and system of discovering materials for use in carbon dioxide separation includes extracting references to chemical molecules from online sources. The extracted references are encoded into chemical formulas. Molecular properties are calculated from the encoded chemical formulas. Features are extracted from the chemical formulas. Molecular properties of predicted molecular structures are predicted through a machine learning engine. The predicted molecular properties are based on the calculated molecular properties and extracted features. Target properties for predicted molecular structures are defined. Synthesized molecular structures are generated. The synthesized molecular structures include predicted molecular properties satisfying the defined target properties.

The present disclosure concerns systems and sorbents for the removal of carbon dioxide from ambient air. In some aspects, the system includes a wind collector, a body and an outlet. The body has a monolith or platforms dispersed therein, surfaces of which are at least partially coated in a sorbent, such that passing ambient air that contacts the sorbent, thereby allowing for the removal of carbon dioxide therefrom. Sorbents of the present disclosure include substrates that are hybrids of a silica, optionally with a carbonaceous material, and an epoxy-modified aminopolymer.

A carbon dioxide containing fluid is flowed through a membrane in an open position. The membrane encapsulates an adsorbent bed operating at a first temperature. The adsorbent bed adsorbs at least a portion of the carbon dioxide of the carbon dioxide containing fluid. The membrane is adjusted to a closed position, thereby isolating the adsorbent bed and preventing fluid flow into and out of the membrane. The adsorbent bed is heated to a second temperature, thereby desorbing the carbon dioxide captured from the carbon dioxide containing fluid. The membrane is adjusted to the open position. The adsorbent bed is cooled to the first temperature.

A mobile emissions control system is provided for diesel engines operated on ocean-going ships at-berth. The emissions control system comprises two essential elements: an emissions capturing system and an emissions control system. The emissions control system may be mounted on a towable chassis or mounted on a barge, allowing it to be placed alongside ocean-going ships at-berth. The emission capturing system captures exhaust from a ship's diesel engine and conducts it into the emissions control system, which cleans the exhaust and then passes clean air into the atmosphere through an exhaust outlet.
