Analysis of a toluene stripping process: a comparison between a microfabricated stripping column and a conventional packed tower

Intensification of G/L absorption in microstructured falling film. Application to the treatment of chlorinated VOC’s – part I: Comparison between structured and microstructured packings in absorption devices

“…Similar compared performance was reported by Cypes and Engstrom for toluene desorption from wastewater using microperforated systems and conventional packed-bed column (Cypes and Engstrom, 2004). …”

“…Therefore, it could be suggested that the data obtained with the absorption column and the microabsorber follow a power-law relationship of the two fluid velocities (Cypes and Engstrom, 2004):…”

“…Such packings have been used for absorption of VOCs or CO 2 (Brunazzi and Paglianti, 1997;Aroonwilas and Tontiwachwuthikul, 1998;Dang Van et al, 1998;Wang et al, 2001), gas-liquid desorption, e.g. removal of VOCs from wastewater by stripping (Hwang et al, 1992;Ortiz-Del Castillo et al, 2000;Cypes and Engstrom, 2004).…”

Separation Units

“…Cypes and Engstrom [54] used a microfabricated stripping column (MFSC) made from two silicon and one glass wafer, similar in design to the mesh microcontactor. The gas-liquid interface was pinned at holes 50 pm x 50 pm, separating the gas and liquid streams that were flowing in 330-pm-deep channels.…”

Stripping as a pretreatment process of industrial oily wastewater

“…The design of a steam stripper for removal of organic pollutants from water has been studied and a simple guideline has been proposed for effective stripping [14][15][16][17][18][19][20].…”
