Our group performs a comparative study in the partitioning behaviour of mercury during the regeneration process of laboratory grade MEG and industrial MEG provided by a natural gas processing plant.
Mercury and its compounds are present in many gas fields worldwide, with levels ranging from 5 × 10−6 to 4.4 g/m3 in some gas fields.
Even trace amounts of mercury can contaminate precious metal catalysts downstream and accumulate in equipment, having adverse effects on the processing of natural gas streams (e.g., liquid-metal embrittlement (LME) of aluminum heat exchangers).
Furthermore, mercury is well-known to be toxic to both humans and the environment. Hence there is significant interest in understanding the chemistry of mercury in natural gas transportation and refinery processes in order to take appropriate mitigation steps.
Our group investigates the partitioning behaviour of mercury during the regeneration process of laboratory grade Monoethylene Glycol (MEG) and the actual industrial MEG provided by a natural gas processing plant.
A comparison of the types of MEG provides an insight into how the Industrial-MEG constituents (salts, organics, etc.) effect mercury partition during MEG regeneration processes.
