Evaluación tecnológica del uso de mezclas de aminas en la remoción de H2S de corrientes gaseosas.

The acid compounds (H2S y CO2) removal from gaseous streams is traditionally carried out in an absorption system based on alkanolamines. The present paper deals with the evaluation of a gas sweetening plant for the H2S removal from hidrotreating products in a heavy oil industry. The efficiency of a typical absorption system running on MDEA/MEA and MDEA/DEA is proved to obtain a lean gas with 40 to 60ppm of H2S. The 90% of the H2S is recovered and the sweet gas can be recirculated to the hidrotreating stage. The modeling and simulation of the process is implemented on Aspen-Hysys software.
