Özet
Natural gas has become a vital energy source due to its abundant availability and relatively low carbon emissions. However, the presence of impurities, such as sulfur compounds, nitrogen compounds, and acidic gases, poses significant challenges in both efficiently using natural gas and addressing its environmental impact. This chapter provides a comprehensive overview of hydrotreating techniques and methods for removing acidic gases during the pretreatment of natural gas. Hydrotreating involves catalytic processes like hydrodesulfurization (HDS) and hydrodenitrogenation (HDN), aimed at converting harmful compounds into less detrimental forms. Within this chapter, detailed discussions cover reaction mechanisms, various catalyst types, and the impact of process conditions on the efficacy of hydrotreating. Furthermore, the chapter explores multiple technologies utilized for eliminating acidic gases, such as carbon dioxide (CO2) and hydrogen sulfide (H2S), from natural gas streams. These methods include absorption, adsorption, and membrane separation. Offering significant insights, this chapter serves as a valuable resource for researchers and industry professionals involved in advancing cleaner and more efficient processes for natural gas pretreatment.
