We are in process of modifying existing gas processing plant to accommodate Mercury Removal Unit (MRU). Exiting system  consists of separator, TEG dehydration unit and compressor. Please advise on following;

 

1) The feasibility of using  single MRU at inlet of separator to treat incoming combine system consisting of gas, oil and water (we have good amount of free water and oil) or use of independent MRU for each product stream.

 

2) Based on internet search it seems there are two type of system one is for dry gas and other is for wet gas (water saturated). Any inputs on this will help.

 

3) Downstream of TEG dehydration,  modification in existing plant seems to be feasible without much disruption in production. what is possibility of mercury contamination in TEG? Any example of plant using this option and how the tackle contaminated TEG? Desktop study suggest that mercury tends to accumulate at regeneration section of TEG  which needs to be cleaned. Any operation based inputs will help to  mitigate/ plan for such problems.

You should also consult with the suppliers of the mercury removal material. They should not be too difficult to find.

Yes we have contacted few MRU supplier and it seems they can handle wet as well as dry gas. I'm looking for some experience base information from operator side.
