Method calculates lean, semilean streams in split-flow sweetening

07/23/2007
Alkanolamines are used widely in gas treating plants. Because acid-gas removal from natural gas requires regeneration of alkanolamines, the energy requirement for the stripping section (condenser and reboiler) will be much greater when the inlet sour gas contains a high concentration of acid gases.In these cases, a split-flow process can reduce energy consumption. Two solvent streams called lean and semilean streams are used.A new method has been devised for calculating these stream rates. The procedure is based on simplifying assumptions that permit quick shortcut calculations.The proposed method has been tested for two plants, the Okotoks sweetening plant in Canada and the Razi petroche...
