| 520 | _aTranscripción del resumen presentado por el autor, en inglés: The effects of ammonia in the feed to amine sweetening units has been investigated using a process simulation program called TSWEET®. In the cases studied, MEA and MDEA were used to treat gases contaminated with up to 0.3% ammonia. The MEA units studied were 1100 psi gas contactors sweetening 0.25 to 4% H2S and 0.25 to 2.5% CO2. The MDEA units were 300 and 20 psi units treating high CO2 streams in a selective manner. Small amounts of ammonia can cause serious problems in some amine sweetening units. These problems are usually traceable to a complex of ammonia with CO2 in the stripper. When large amounts of CO2 are present, this complex may cause a build up of CO2 and ammonia in the circulating amine. In MEA, ammonia tends to push CO2 into the reboiler, increasing the CO2 residuals and ammonia in the lean amine. In MDEA, the ammonia appears to help drive CO2 overhead, decreasing CO2 and increasing the H2S in the stripper bottoms. | ||
