This invention deals with an emission capture device with grease which is composed of a main duct, here it is connected to the outlet of the emitter of particles which are required to be treated (said emitter is conventional, such as an internal combustion engine exhaust, incinerator duct, meat roaster chimney, etc. Just to mention a few), it is then absorbed and propelled by an electric fan, from which its wind force drives the emissions into the emissions capture tank, the mechanism to dissolve the particulate emissions inside the tank is composed of, The mechanism to dissolve the emission particles inside the tank is composed of the main duct inside the tank, which reaches the upper part of the tank, making a spiral return to the lower part of the tank, having the main duct as its end, through which the emission already dissolved in the liquid comes out, between the mechanism to dissolve the emission and the walls of the tank it has four supports, in the upper part of the tank it has its outlet duct to the open air, it also has four liquid inlet ducts, At the bottom of the tank there are two outlets to drain the liquid and direct it to a cooling device, and from there it is transported through a duct to a decanter tank, which in its lower part has a decanter tank, and at the same time it is transported to the bottom of the tank, On one side of the decanter tank is a duct that is connected directly to a pump that is responsible for driving and supplying the liquid through its outlet duct directly to the ducts that are responsible for distributing the liquid to the emissions capture tank and its mechanism to dissolve the emissions that are treated there.

The present invention relates to a method for carbon dioxide capture and concentration by partitioned multistage circulation based on mass transfer-reaction regulation. In the present invention, multiple means such as multistage circulating absorption, intelligent multi-factor regulation, pre-washing and cooling, inter-stage cooling, post-stage washing, slurry cleaning, cooling water waste heat utilization, small-particle-size and high-density spraying, external strengthening field such as a thermal field/ultrasonic field/electric field, and catalysis by composite catalyst are adopted, so that the target for low cost, low energy consumption, stability and high efficiency is realized. The secondary pollutants are effectively inhibited while carbon dioxide is efficiently captured; meanwhile, high-efficiency capture, low-energy desorption, and high-purity concentration of carbon dioxide are implemented. From top to bottom in sequence, the multistage circulation is used to remove aerosols, improves carbon capture efficiency, maintains absorption rate, concentrates solution, which reduces the carbon emission reduction cost.

Primary, secondary (1°,2°) alkylethylenediamine- and alkylpropylenediamine-appended variants of metal-organic framework are provided for CO.sub.2 capture applications. Increasing the size of the alkyl group on the secondary amine enhances the stability to diamine volatilization from the metal sites. Two-step adsorption/desorption profiles are overcome by minimzing steric interactions between adjacent ammonium carbamate chains. For instance, the isoreticularly expanded framework Mg.sub.2(dotpdc) (dotpdc.sup.4−=4,4″-dioxido-[1,1′:4′,1″-terphenyl]-3,3″-dicarboxylate), yields diamine-appended adsorbents displaying a single CO.sub.2 adsorption step. Further, use of the isomeric framework Mg-IRMOF-74-II or Mg.sub.2(pc-dobpdc) (pc-dobpdc.sup.4−=3,3-dioxidobiphenyl-4,4-dicarboxylate, pc=para-carboxylate) also leads to a single CO.sub.2 adsorption step with bulky diamines. By relieving steric interactions between adjacent ammonium carbamate chains, these frameworks enable step-shaped CO.sub.2 adsorption, decreased water co-adsorption, and increased stability to diamine loss. Variants of Mg.sub.2(dotpdc) and Mg.sub.2(pc-dobpdc) functionalized with large diamines such as N-(n-heptyl)ethylenediamine have utility as adsorbents for carbon capture applications.
