“…Sobieszuk et al [12] further found that the enhancement of the overall rate of the mass transfer depends on the gas concentrations. Ichiyanagi et al [22] performed detailed three-dimensional measurements of the velocity and concentration distributions for CO 2 dissolution process through the gas-liquid interface in microchannels by using the advanced technique confocal micron-resolution particle image velocimetry (micro-PIV) combined with laser-induced fluorescence (LIF). The LIF measurement demonstrated that the dissolved gas in the spanwise direction decreases with the increase of the Reynolds number.…”

The abnormal climate change has made the reduction of CO 2 emission that received worldwide attention. The integration of CO 2 capture-sequestration application for enhanced oil recovery (EOR) technology will be the new trend. Several scholars have applied microfluidics in CO 2 capture, oil and gas analysis, and CO 2 sequestration. The mass transfer process for CO 2 capture can be intensified owing to the large specific surface/ volume ratio and high contact area in microchannels. The small amount of feeding volumes of oil and gas samples and the quick response for the analysis make the microfluidics a promising tool for the oil and gas analysis. Moreover, microfluidics can reveal the transport mechanism at microscale for multiphase interfacial phenomena in microchannels within porous media during the CO 2 flooding process in line with the pressure, temperature, and material properties of the rock within the oil reservoir. This chapter will elaborate the progress of the application of microfluidic technology in the utilization of CO 2, including the mechanism of mass transfer for CO 2 in microreactors, the advantages of microfluidics in oil and gas analysis, and the fundamentals of microfluidics in CO 2 flooding, oil recovery improvement, and CO 2 sequestration.

This research reports a novel method for depth position measurement of fast moving objects inside a microfluidic channel based on the chromatic aberration effect. Two band pass filters and two avalanche photodiodes (APD) are used for rapid detecting the scattered light from the passing objected. Chromatic aberration results in the lights of different wavelengths focus at different depth positions in a microchannel. The intensity ratio of two selected bands of 430 nm-470 nm (blue band) and 630 nm-670 nm (red band) scattered from the passing object becomes a significant index for the depth information of the passing object. Results show that microspheres with the size of 20 lm and 2 lm can be resolved while using PMMA (Abbe number, V ¼ 52) and BK7 (V ¼ 64) as the chromatic aberration lens, respectively. The throughput of the developed system is greatly enhanced by the high sensitive APDs as the optical detectors. Human erythrocytes are also successfully detected without fluorescence labeling at a high flow velocity of 2.8 mm/s. With this approach, quantitative measurement for the depth position of rapid moving objects inside a sealed microfluidic channel can be achieved in a simple and low cost way.
