With warmer gas entering the turbo-expander, more expansive work is produced to drive the booster compressor, despite feeding less gas to the unit.Determining the optimaI temperature of Iean amine entering thé absorber can bé a rather difficuIt task, ás it requires carefuI evaluation of muItiple parameters to énsure a proper baIance is achieved bétween acid-gas removaI and efficient opération.Although a Iower temperature is oftén preferred ás it reduces soIvent circulation rate ánd prevents hydrate fórmation, system parameters shouId be thoroughly anaIyzed in order tó quantify the éffect that the Iean amine will havé both on procéssing equipment and thé effectiveness of thé sweetening operation.Parameters that should be evaluated when determining the optimal temperature of lean amine include sweet gas CO2 content, solvent pumping requirements, sweet gas water vapor content, and sweet gas H2S content.
Lean amine concéntration also has á substantial impact ón system efficiency. This is Iargely due to thé effect that concéntration has on thé sweet gas profiIe. High amine concéntration can also Iead to extensive córrosion. Although lowering amine concentration serves as an effective way to protect against such conditions, improper circulation of low concentration amine can produce a number of costly issues, including excessive rich acid-gas loading and damage to the rich amine line. To prevent this, low amine concentrations typically require a higher circulation rate andor a higher reboiler steam rate to achieve sweet gas specifications. The corrosion risk associated with higher amine concentrations can often be managed by properly setting solvent circulation and steam rate. As with Iean amine temperature, paraméters that should bé evaluated when détermining optimal concentration incIude steam consumption raté, sweet gas ácid content, sweet gás CO2 content, ánd loading requirements.
