SILVA, A.; CASTILLO, C.  and  KRASUK, J. H.. Minimum gas flow rate in a countercurrent isothermal gas stripper. Lat. Am. appl. res. [online]. 2004, vol.34, n.4, pp.213-216. ISSN 0327-0793.

It is presented an analytical expression for the minimum gas flowrate required for the design of an isothermal countercurrent gas stripper, when Henry's law (H > 1) applies and the gas and liquid streams are concentrated in the soluble gas of the binary gas mixture. This solution allows for a faster and more accurate result, for (GB)_min, than the graphical procedure presently in use.
