Crude Oil: Case 3

Midstream Company's Pipeline

Tailgate Testing

  • A midstream company is unable to sell oil with 800 ppm H₂S from 15,000 barrels of crude in a 24-inch mainline.

  • Knockout submitted a proposal of 2.9 to 3.4 gal/min into the 24-inch mainline.

  • The injection was 75 yards upstream of two mainline pumps before leaving the station.

  • The H₂S level at the discharge of the station was reduced to 10ppm after treatment with Knockout.

  • At the inlet to the next station, 65 miles away, the H₂S levels remained below 10 ppm.

Day 1

Day 2

Takeaways

  • H₂S levels at discharge of the station were reduced to below 10 ppm after treatment

  • The H₂S levels remained below 10 ppm at the inlet station (65 miles away), showing the reaction is irreversible

  • The H₂S to chemical ratio that achieved below 10 ppm H₂S was 8:1
