| 520 | |b Mellitah gas plant uses the MDEA solution as a solvent for gas sweetening process. Selectivity of MDEA over MEA and DEA leads to saving energy for amine regeneration and solution circulation rate. However, the MDEA does not react directly with CO2 particularly as an extensive amount of CO2 is required to be removed. At Mellitah gas plant the concentration of CO2 is high (14.5% vol.) and H2S concentration is 1.2 % vol. To overcome this disadvantage, Mellitah gas plant uses the MDEA solution with absorber plate weir height of 100 mm to increase the holdup time up to 3.6 seconds instead of standard plate weir height of 50 mm. The absorption column with plate weir height of 100 mm requires design of a special column which costs more. To avoid paying extra money for design of a special column, secondary amines such as MEA or DEA have to be added to MDEA solution as activators to increase the reaction rate of MDEA solution with CO2. Gas sweetening process at Mellitah gas plant was placed under investigation with the use Aspen HYSYS software v.8 as a simulator. In addition, optimization by two blends of amines (a 40% wt MDEA with 10% wt DEA blend, and a 40% wt MDEA with 10% wt MEA blend) using standard plate weir height of 50 mm. This study showed that the two blends of the amine can remove the acid gasses from the raw natural gas to required specifications. In contrast, 40% MDEA with 10% DEA blend was the optimum because of its lower reboiler duty for amine regeneration, lower losses of amines in the sweet gas stream but requires more amines circulation rate. Moreover, the specification of the sweet gas stream was 0.492 ppm H2S and 0.055% CO2 at amine circulation rate of 1200 m3/h and lean amine temperature of 35˚C. In addition, the optimization work illustrated that the CO2 absorption rate in the 40% MDEA with 10% DEA blend was 2.5 times greater than that for CO2 absorption in the 50% MDEA solution at amine circulation rate of 1200 m3/h. The 40% MDEA & 10% DEA blend is the recommended one for optimization the gas sweetening process at Mellitah gas plant. | ||
