Emissions & Flares: 2018 #50

Problem 50: Which of the following statements concerning flaring is most FALSE? 

(A) All hydrocarbons with a C-to-H ratio of greater than 0.33 tend to soot. 
(B) Combustion efficiency of 98% is equivalent to a destruction efficiency of 96.5%. 
(C) Combustion efficiency is the % of HC in flare vent gas completely converted to CO2 & H2O. 
(D) Petro refinery flare: NHV of gas in flare combustion zone is >= 270 Btu/ft3 for 98% destruction.

This answer are easily found on 8 FAC 9. On (B), the 96.5% & 98% are merely reversed.
