Abstract

Acid gas cleaning is one of the natural gas processing steps where the acid gases are removed to satisfy the quality of the sweet gas. Conventionally, this is achieved by processing the sour gas through an acid gas removal (AGR) unit to produce the desired sweet gas, while concentrating the H₂S gas in the acid gas enrichment (AGE) unit. In this study, a novel acid gas cleaning design has been proposed that can significantly reduce the energy requirement while maintaining all the streams design specifications. The proposed design recommends to first produce acid gas with the required purity and then producing the sweet gas in another AGR unit. The results show that the proposed design requires 22 % lower operational energy compared to the base design.
