Membrane Absorption

<div> <p>With the aggravation of the unprecedented greenhouse effect, the reduction of greenhouse gases which mainly consist of CO<sub>2</sub> has caught high attention by global scholars. The membrane absorption of CO<sub>2</sub> from the flue gas seems a promising alternative to conventional absorption methods like chemical absorption. In this article, the principles of the membrane absorption process were discussed. The research development and current status of CO<sub>2</sub> capture in flue gas using a hollow fiber membrane contactor were reviewed. The affecting factors included the membrane structure and material, module connection form, gas and liquid flow pattern and absorbent. Also, these factors that affected the separation performance of mass transfer processes, as well as the mass transfer coefficients and models for CO<sub>2</sub> absorption were critically discussed in the tube side, shell side and membrane. Also, an experiment system for CO<sub>2</sub> absorption in a membrane contactor was dipicted. The modeling works were validated with experimental results. Additionally, the deficiencies of present development in membrane gas absorption of acid gases and recommendations for future pilot-scale applications were proposed.&nbsp;</p> </div> <p>&nbsp;</p>

AbstractCell-assisted lipotransfer (CAL) is an advanced lipoinjection method that uses autologous lipotransfer with addition of a stromal vascular fraction (SVF) containing adipose-derived stromal stem cells (ASCs). The CAL procedure of manual isolation of cells from fat requires cell processing to be performed in clean environment. To isolate cells from fat without the need for a cell processing center, such as in a procedure in an operation theater, we developed a novel method for processing SVF using a closed cell washing concentration device (CCD) with a hollow fiber membrane module. The CCD consists of a sterilized closed circuit, bags and hollow fiber, semi-automatic device and the device allows removal of >99.97% of collagenase from SVF while maintaining sterility. The number of nucleated cells, ASCs and viability in SVF processed by this method were equivalent to those in SVF processed using conventional manual isolation. Our results suggest that the CCD system is as reliable as manual isolation and may also be useful for CAL. This approach will help in the development of regenerative medicine at clinics without a cell processing center.
