Question 3213 Deck General

The correct answer is B) Only 80% of the H2S will be converted to SO2 or free sulfur. When H2S is burned (flared) on a MODU, the combustion process will convert approximately 80% of the H2S to sulfur dioxide (SO2). The remaining 20% of the H2S may be converted to free sulfur or other sulfur compounds, but will not be completely eliminated. This is based on the typical efficiency of H2S combustion processes. The other answer choices are incorrect because A) assumes complete conversion to SO2, C) assumes complete conversion to hydrogen and free sulfur, and D) is incorrect as the unconverted H2S can still be dangerous if not properly managed.
