Abstract

A new process has been developed as a joint collaboration between PETRONAS Research and QUILL, and covers the removal of mercury from natural gas feeds. The process utilises ionic liquids to provide a novel active site for mercury capture. The approach incorporates two key aspects: (i) custom design of ionic liquids with a dual functionality to both oxidise and capture mercury, and (ii) impregnation of the ionic liquids on an inert porous support as solid-supported ionic liquids, SSILs. This allows them to be used directly in existing MRU plants without requiring any changes to process operation, or additional costs associated with plant modification. The efficiency of the SSIL has been explored in direct comparison with commercial sulfur-impregnated activated carbons and, in laboratory trials, increases in bed life-time of up to five-fold have been observed.
