Rectisol process can selectively remove hydrogen sulfide and carbon dioxide from the raw gas effectively. Due to structural constraints of typical process, there are issues with CO2 emissions high energy consumption. Improving its recovery not only alleviates burden but also contributes emission reduction. Therefore, a novel for H2S enrichment capture is proposed in this paper. To realize these, CO2-lean solvent circulation integrated based on process. And an optimization framework optimize performance column equipment using TOPSIS method. According evaluations technical, economic environmental perspectives, results, sulfur ratio (2.09), return investment (14.34) (0.69) demonstrate that offers both advantages comparison The reduce consumption, exergy efficiency still needs be improved through thermodynamic analysis. It beneficial conservation detrimental conversion. This study provides new idea development achieve

Rectisol process can selectively remove hydrogen sulfide and carbon dioxide from the raw gas effectively. Due to structural constraints of typical process, presence large amounts increases its energy consumption emissions. Reasonable capture structure in not only alleviate burden but also contribute emission reduction. Therefore, this paper integrates a H2S enrichment CO2-lean solvent circulation into for investigation. In paper, novel CO2 is proposed.

In recent years, non-aqueous iron-based ionic liquid desulfurization technology has overcome the limitations of by-reaction in aqueous system, but its lower sulfur capacity and reaction activity have hindered industrial application. this work, a novel chelated deep eutectic solvent (Fe-DES-MDEA) was synthesized by combining (BmimFeEDTA) with an alcoholic amine (MDEA) for oxidative hydrogen sulfide. Fe-DES-MDEA exhibited superior regeneration properties compared to conventional wet desulfurizers. Remarkably, even after five cycles, maintained consistent efficiency, sulfide being converted targeted manner without formation by-products. Characterization techniques including TG, FT-IR, Py-IR, CV were employed analyze microstructure catalytic Fe-DES-MDEA. Additionally, DFT calculations revealed that transition MDEA/[HMDEA]+ facilitated cycling performance Fe(III)/Fe(II) oxidation H2S. Furthermore, molecular cage DES mitigated excessive O2 activation, enabling directed conversion H2S, reminiscent mechanism "vacating change bird". Consequently, shows significant promise realm removal.
