Girbotol Girdler Bottoms
Girbotol Girdler Bottoms :
Also spelled Girbitol. A gas scrubbing process using an alkanolamine as the absorbent. Used for removing hydrogen sulfide from refinery and natural gases, and carbon dioxide from hydrogen and combustion products. The gases are subsequently removed by steam stripping. Monoethanolamine, diethanolamine, and triethanolamine have all been used. The process depends on the reversible formation of an amine carbonate: 2HO•C2H4•NH2 + H2O + CO2 D (HO•C2H4•NH3)2CO3 Invented in 1930 by R. G. Bottoms at the Girdler Corporation, Louisville, KY. In 1950 it was the most commonly used process for removing hydrogen sulfide from refinery and natural gases. (Check source for accuracy of chemical formula)
