IONIC LIQUID AND SOLVENT MIXTURES FOR HYDROGEN SULFIDE REMOVAL |
摘要 |
<p>The invention comprises a process for removal of hydrogen sulfide from gaseous mixtures. The process involves the use of a mixture of a physical absorption solvent and an ionic liquid. The mixtures provided improved absorption of hydrogen sulfide, when compared to physical absorption solvents without the ionic liquid at low partial pressures of hydrogen sulfide. A regeneration cycle involving the addition of a solvent, such as water, is used to regenerate the mixture.</p> |
