  • Patent number: 11052324
    Abstract: Systems and methods are provided for improving process control of separation systems that include one or more dividing walls within a single column. It has been discovered that improved process control can be achieved by controlling the dividing wall columns based on energy balance instead of mass balance. The energy balancing can be performed in part based on controlling temperature at a plurality of locations on the feed side within a first divided portion of the column. Using energy balancing based on temperature control at a plurality of locations on the feed side can facilitate maintaining the operation of the dividing wall columns within a single region of phase space that can be suitably approximated by linear models. This can allow conventional process controllers to manage the manipulated and controlled variables. In addition to controlling the temperature at a plurality of locations on the feed side, a plurality of other characteristics can be used as manipulated or controlled variables.

  • Patent number: 11046896
    Abstract: A process for cleansing a liquid of volatile contaminants can be accomplished by cross flowing a liquid through a contactor vessel. As the liquid cross flows through the horizontal contactor vessel, a radial flow pattern is induced in the liquid and the liquid is contacted with a cleansing gas. As the liquid moves through the contactor vessel, contaminants enter the cleansing cross current gas percolating through the liquid. The cross current gas may then be collected and cleansed of the contaminants it collected. The cleaned cleansing gas may then be recycled back into the contactor vessel.

  • Patent number: 11014067
    Abstract: Polyamines with lengths carefully tailored to the framework dimensions are appended to metal-organic frameworks such as Mg2(dobpdc) (dobpdc4-=4,4?-dioxidobiphenyl-3,3?-dicarboxylate) with the desired loading of one polyamine per two metal sites. The polyamine-appended materials show step-shaped adsorption and desorption profiles due to a cooperative CO2 adsorption/desorption mechanism. Several disclosed polyamine-appended materials exhibit strong ability to capture CO2 from various compositions. Increased stability of amines in the framework has been achieved using high molecular weight polyamine molecules that coordinate multiple metal sites in the framework. The preparation of these adsorbents as well as their characterization are provided.

  • Patent number: 10953385
    Abstract: Primary, secondary (1º,2º) alkylethylenediamine- and alkylpropylenediamine-appended variants of metal-organic framework are provided for CO2 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 minimizing steric interactions between adjacent ammonium carbamate chains. For instance, the isoreticularly expanded framework Mg2(dotpdc) (dotpdc4?=4,4?-dioxido-[1,1?:4?,1?-terphenyl]-3,3?-dicarboxylate), yields diamine-appended adsorbents displaying a single CO2 adsorption step. Further, use of the isomeric framework Mg-IRMOF-74-II or Mg2(pc-dobpdc) (pc-dobpdc4?=3,3-dioxidobiphenyl-4,4-dicarboxylate, pc=para-carboxylate) also leads to a single CO2 adsorption step with bulky diamines.
