Does anyone have references that document the increase in NO2 emissions on from the exhaust of gas turbines (CTG's) due to increases in C2, C3, C4 prevalent in "rich" LNG, such as sourced from Qatar?
There are many new recieving terminals being permitted and in the construction phase, yet none are currently proposed to have gas processing facilities ( ie, C2+ stripping with methane reformers ). The result will be an increase in C2,C3,C4 in the pipeline gas, yet current proposals are only to control Wobbe, HHV and density by N2 injection. The unspoken problem is that the higher C2+ levels are reported to increase the NO2 in the exhaust of CTG's, and this supposedly leads to a "brown plume" oo simple cycle CTG's and reduced de-Nox activity of the SCR on combined cycle CTG's.
