News and updates from Qa3

Qa3 has submitted its abstract for consideration for presentation at the ICMGP 2019 14th International Conference on Mercury as a Global Pollutant to be held this September in Krakow Poland. The abstract focuses on Mercury Released from Mercury Contaminated Steel During Smelting. Qa3 chaired the dedicated oil and gas session at the last ICMGP conference held in the USA and look forward to exchanging knowledge with other in the industry at this year’s event.

Qa3 frequently give oral presentations on the topic of “mercury loss to various process systems across a gas processing facility”. One key process is dehydration of gas using either gylcol or molecular sieve. Both have the secondary effect of removing mercury from the gas via adsorption (rather than chemical reaction), typically between 10 - 30% of the mercury. During the regeneration cycle of the glygol / molecular sieve, trapped mercury will be released resulting in a regeneration gas containing a high concentration of mercury. It is therefore very important to consider the fate of this regeneration gas whether that be flaring or fed back into the process.
