Abstract. We report in this paper the development of an embedded ultralight spectrometer (<3 kg) based on tuneable diode laser absorption spectroscopy (with a sampling rate of 24 Hz) in the mid-infrared spectral region. This instrument is dedicated to in situ measurements of the vertical profile concentrations of three main greenhouse gases – carbon dioxide (CO2), methane (CH4) and water vapour (H2O) – via standard weather and tethered balloons. The plug and play instrument is compact, robust, cost-effective, and autonomous. The instrument also has low power consumption and is non-intrusive

The absorption performance of CO2 from the simulated flue gas using fresh MDEA-PZ-TETA absorbent and the desorption behavior of CO2 from the CO2-saturated absorbent were investigated. In the process of CO2 absorption, the absorption temperature and the inlet flow rate of CO2 played important effects on the absorption performance. The experimental results showed that the suitable absorption condition of CO2 using fresh absorbent was the absorption temperature of 20 oC for 18 min and the inlet flow rate of CO2 of 50 mL/min.

Increases in ambient CO2 tension increase colonic sodium absorption by increasing mucosal to serosal sodium flux. We examined the membrane site of CO2 action by utilizing the polyene antibiotic nystatin to create aqueous pores in the apical membrane. Under these conditions, the basolateral rather than the apical membrane is rate limiting for sodium absorption. Pairs of stripped rat distal colonic segments were mounted in modified Ussing chambers in a Ringer-HCO3 solution gassed with either 3% CO2-97% O2 or 11% CO2-89% O2.

Using cheap and porous diatomite or zeolite as silicon sources, we prepared firstly Li4SiO4 matetials for high temperature CO2 capture through solid-state method, and mainly investigated effects of silicon sources on the CO2 absorption properties of Li4SiO4 materials. Phase composition was analyzed by X-ray diffraction, and the CO2 absorption properties were studied by the simultaneous thermal thermogravimetric analyzer (TG-DSC). The results showed that Li4SiO4 materials using zeolite as silicon source showed little CO2 absorption properties, while Li4SiO4 materials using diatomite as silicon

Carbon dioxide (CO2) absorption in a non-aqueous solution is a potential technology for reducing greenhouse gas emissions. In this study, a non-aqueous solvent, sulfolane and dimethylsulfoxide (DMSO), was functionalized with a deep eutectic solvent (DES) consisting of choline hydroxide and polyamines diethylenetriamine (DETA) and triethylenetetramine (TETA). The non-aqueous absorbents’ CO2 absorption ability was investigated in a high-pressure absorption reactor with a variable absorption temperature (303.15–333.15 K) and pressure (350–1400 kPa). The results showed that 2M ChOH:TETA−DMSO solut

Experimental and analytical studies of CO2 absorption performance are carried out in a gas-liquid two-phase flow atomizer on the basis of a gas diffusion model. The gas-liquid two-phase flow atomizer with high spray efficiency and low power consumption has been applied to CO2 absorption. Experiments for the CO2 absorption were conducted in an isolated room and the results showed that, the mist sprayed by the improved atomizer can effectively reduce the CO2 concentration. Furthermore, a CO2 diffusion model was developed to predict the absorption process. This model was validated through a compa

Carbon capture and storage (CCS) technology is considered as one of the most effective short-term solutions in reducing atmospheric CO2 concentrations. A key of CCS technology is to seek the absorbent with low cost, fast absorption rate, and high stability. In this study, we show that 2-ethyl-4-methylimidazole is particularly suitable for efficient CO2 capture. The aqueous solution of 2-ethyl-4-methylimidazole displays a maximum CO2 molar absorption capacity of 1.0 mol∙mol−1 and the absorbed CO2 can be completely released through heating the solution at a relatively low temperature (<100 °C

The absorption efficiencies of CO2 in ceramic hollow-fiber membrane contactors using monoethanolamine (MEA) absorbent under both cocurrent- and countercurrent-flow operations were investigated theoretically and experimentally; various MEA absorbent flow rates, CO2 feed flow rates, and inlet CO2 concentrations were used as parameters. Theoretical predictions of the CO2 absorption flux were analyzed by developing the mathematical formulations based on Happel’s free surface model in terms of mass transfer resistances in series. The experiments of the CO2 absorption were conducted by using alumina

Lithium silicate (Li4SiO4) material can be applied for CO2 capture in energy production processes, such as hydrogen plants, based on sorption-enhanced reforming and fossil fuel-fired power plants, which has attracted research interests of many researchers. However, CO2 absorption performance of Li4SiO4 material prepared by the traditional solid-state reaction method is unsatisfactory during the absorption/regeneration cycles. Improving CO2 absorption capacity and cyclic stability of Li4SiO4 material is a research highlight during the energy production processes. The state-of-the-art kinetic an
