Title 40Chapter ISubchapter CPart 60Subpart OOOO → Appendix


Title 40: Protection of Environment
PART 60—STANDARDS OF PERFORMANCE FOR NEW STATIONARY SOURCES (CONTINUED)
Subpart OOOO—Standards of Performance for Crude Oil and Natural Gas Facilities for Which Construction, Modification, or Reconstruction Commenced After August 23, 2011, and on or Before September 18, 2015


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

H2S content of acid gas (Y), %Sulfur feed rate (X), LT/D
2.0 ≤ X ≤ 5.05.0 < X ≤ 15.015.0 < X ≤ 300.0X > 300.0
Y ≥ 5074.085.35X0.0144Y0.0128 or 99.9, whichever is smaller.
20 ≤ Y < 5074.085.35X0.0144Y0.0128 or 97.5, whichever is smaller97.5

Y < 1074.074.074.074.0

X = The sulfur feed rate from the sweetening unit (i.e., the H2S 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 H2S (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. Zi refers to the reduction efficiency required at the initial performance test. Zc refers to the reduction efficiency required on a continuous basis after compliance with Zi has been demonstrated.
