Abstract

This study compared and characterised  hybrid amine-local solvent blends for sustainable natural gas sweetening. The study designed and evaluated an absorption process using blends of monoethanolamine (MEA) with solvents derived from agricultural waste Plantain Peel Ash Extract (PPAE) and Coconut Shell Ash Extract (CSAE). The comprehensive characterisationprovided fundamental insights into the viability of using agricultural waste for gas sweetening. Plantain peels' high volatile matter (74.3%) yields ash rich in active alkaline compounds during calcination, while coconut shells' higher fixed carbon (19.5%) produces more stable char with lower alkaline content. The ultimate analysis showed that coconut shells' higher carbon content (49.5%) aligns with its lignocellulosic nature, while plantain peels' higher oxygen content (47.5%) indicates more carbohydrate-rich material that decomposes to yield higher ash alkalinity.The electrolyte properties further confirm PPAE's superiority, with higher pH (12.1), conductivity (28.5 mS/cm), and ionic strength (0.42 mol/L), all contributing to better absorption performance while influencing corrosion behavior.

Abstract

 This study optimised hybrid amine-local solvent blends for sustainable natural gas sweetening, tackling corrosion and environmental footprint of imported monoethanolamine (MEA). The study designed and evaluated an absorption process using blends of MEA with solvents derived from agricultural waste Plantain Peel Ash Extract (PPAE).  The study integrates computational corrosion prediction models from the outset, acknowledged and addressed a common deficiency, performance optimisations were evaluated with critical material compatibility constraints from the beginning.Corrosivity assessment predicted a manageable corrosion rate of 0.29 mm/year for the optimal blend, within acceptable limits for carbon steel with standard inhibition. The study conclusively establishes the 50/50 MEA/PPAE hybrid solvent as a technically robust and  environmentally superior alternative. It successfully valorises local agricultural waste, reduces dependency on imported chemicals, and aligns with Nigeria's local content policy and global sustainability goals, offering a viable pathway for greener and more cost-effective natural gas processing.
