Abstract

The sweetening process with amine is widely used to remove acidic gases. However, this process requirement is cooling and heating energies. In addition, the reduction of energy requirements is limited by optimizing operational parameters. Therefore, changing the process parameters can lead to a significant reduction in energy consumption, resulting in lower operating costs. In this study, parameters such as the amine temperature in the entrance of the regeneration tower, the condenser heat load, the reboiler heat exchanger and the heat load of the rich/lean amine gas sweetening unit were investigated and the optimum temperature value to reduce operating costs and increase profitability achieved. Simulation analysis was performed using PRO II software. The comparison between the main process and the optimized process showed that the optimal temperature selection of the rich amine to the recovery tower has the ability to reduce operating costs to over $ 97704 per year, while also leading to the highest recovery of hydrogen sulfide.
