Choose your answer
Natural gas flares is one of the environmental hazards of Carbon fuel extraction. Which of the following statements are correct related to flare gas?
A. It is a byproduct of oil and gas recovery
B. It produces clouds of dust
C. It is a byproduct of landfill gas production
D. It introduces Sulphur dioxide into the atmosphere
E. Microorganisms can only be used to mitigate this hazard
Answer and explanation
Correct answer B
Gas flaring is the controlled burning of natural gas that is generated as a byproduct during oil and gas extraction/recovery (A) as well as during landfill gas management (C). When sour gas containing hydrogen sulphide (H2S) and other sulphur compounds is flared, it oxidizes and introduces Sulphur dioxide (SO2) into the atmosphere (D), whereas it does not produce clouds of dust (B) nor is mitigation limited solely to microorganisms (E). Thus, A, C, D only are the correct statements.
