Abstract: An exemplary embodiment of the present invention provides a carbon-dioxide (“CO2”) sequestration system comprising a CO2 source, a process-water source, a membrane module, and a sequestration duct. The membrane module comprises a first section, a second section, and a membrane. The first section can be configured to receive gaseous CO2 at a first pressure from the CO2 source. The second section can be configured to receive process-water at a second pressure from the process-water source, wherein the first pressure is greater than the second pressure. The membrane can be positioned between the first section and the second section and can comprise a plurality of apertures configured such that the gaseous CO2 passes through the plurality of apertures and dissolves into the process-water to form a process-water-CO2-solution. The sequestration duct can be in fluid communication with the second section and configured to transport the process-water-CO2 solution to a sequestration site.

Abstract: The present disclosure provides improved systems, assemblies and methods to remove and recover CO2 from emissions. More particularly, the present disclosure provides improved membrane contactors configured to remove CO2 from flue gas by temperature swing absorption. In exemplary embodiments, the present disclosure provides a novel hollow fiber membrane contactor that integrates absorption and stripping using a nonvolatile reactive absorbent (e.g., 80% polyamidoamine (PAMAM) dendrimer generation 0, and 20% of an ionic liquid (IL)). Equilibrium CO2 absorption in the nonvolatile viscous mixed absorbent is as high as 6.37 mmolCO2/g absorbent in the presence of moisture at 50° C. A novel membrane contactor is provided for CO2 absorption and stripping via a process identified as temperature swing membrane absorption (TSMAB). The contactor integrates non-dispersive gas absorption and hot water-based CO2 stripping in one device/assembly containing two sets of commingled hollow fibers.

Abstract: The present disclosure concerns a method and detector (10) for detecting an analyte (1) in a sample volume (2), such as nitrosamine in an amine solvent. The method comprises measuring a resonance Raman spectrum (I1) with a first light beam (PI) matching an electronic transition of the analyte (1). The detection of the analyte is enhanced by measuring an off-resonance Raman spectrum (12) using a second light beam (P2) that is shifted in wavelength at least 10 nm away from the electronic resonance. The resonance Raman signal (S1) of the analyte (1) is isolated from the background (Q1, Q2) by a difference analysis between the resonance and off-resonance Raman spectra (I1, I2). The method and detector (10) can be employed for detecting nitrosamine in a carbon capture process or plant (20) that employs an amine solvent.
