- This paper summarises the largest industrial application of a supported ionic liquid process in the Oil & Gas Industry. The challenge the team of researchers had to meet was a process that captured all types of mercury in natural gas (metallic, salts and organo mercury). This was achieved with an oxidative system based around a supported chlorocuprate ionic liquid that retained the trapped mercury species. The “support” phase development was crucial to minimise diffusion constraints in the pellet and optimise pressure drop in reactors. The technology won a triple ICHEME award and has operated for 4 years in industrial units.
