Simulation and Performance Improvement of natural gas sweetening plant using Aspen HYSYS

This work investigates gas sweetening unit. this unit is designed mainly to use Methyl diethanolamine (MDEA) as a solvent for the removal of H۲S and CO۲ from the raw gas. Thus, the handling of higher gas production rates for the forthcoming years is a bottleneck without being upgraded. This work aims to increase throughput and reduce operating costs while maintaining the product quality of these units. HYSYS simulation was used to simulate the processes, assess the potential advantages of using a blend of MDEA and Piperazine, and investigate important parameters in the process. Results show that the MDEA/PZ blend provides high-performance as a gas treating solvent. The sulfur recovery unit simulated in this article also emphasizes on not burning the acid gases produced from the sweetening process and not harming the environment.
