For example , at a flow rate of 12 . 6 Lpm , the DRE for NG decomposition was
found to be 99 . 2 percent . At the same time , the [ NG ] in the exit flow dropped
from 12 . 5 ppmv to a level just below 0 . 1 ppmv . 0 . 01 Fraction NG remaining .

During the start up , the collector is focused and the tank concentration does not
change for the amount of time ( t1 = Vp / q ) it takes for the fluid to flow from the
end of the reactor through the piping to the tank . For very short lengths of piping
