Table 2 to Subpart OOOO of Part 60—Required Minimum SO2 Emission Reduction Efficiency (Zc)

H₂ S content of acid gas (Y), %	Sulfur feed rate (X), LT/D
2.0 ≤ X ≤ 5.0	5.0 < X ≤ 15.0	15.0 < X ≤ 300.0	X > 300.0
Y ≥ 50	74.0	85.35X^0.0144 Y^0.0128 or 99.9, whichever is smaller.
20 ≤ Y < 50	74.0	85.35X^0.0144 Y^0.0128 or 97.5, whichever is smaller	97.5
10 ≤ Y < 20	74.0	85.35X^0.0144 Y^0.0128 or 90.8, whichever is smaller	90.8	90.8
Y < 10	74.0	74.0	74.0	74.0
X = The sulfur feed rate from the sweetening unit (i.e., the H₂ S in the acid gas), expressed as sulfur, Mg/D(LT/D), rounded to one decimal place.
Y = The sulfur content of the acid gas from the sweetening unit, expressed as mole percent H₂ S (dry basis) rounded to one decimal place.
Z = The minimum required sulfur dioxide (SO₂) emission reduction efficiency, expressed as percent carried to one decimal place. Z_i refers to the reduction efficiency required at the initial performance test. Z_c refers to the reduction efficiency required on a continuous basis after compliance with Z_i has been demonstrated.
