H2S Removal From Natural Gas Amine
Hydrogen Sulfide (H2S) is one of the most problematic and costliest contaminants in natural gas processing. Its presence in natural gas poses a significant risk to employees, equipment, compliance, and profitability.
Effective removal of H2S is essential to meeting strict pipeline quality standards, protecting critical assets, and maintaining reliable operations.
Activated carbon is a proven technology for removing H2S from natural gas streams, providing predictable performance without many of the operational challenges associated with conventional scavenger technologies.
NORIT's PETRODARCO® H2S activated carbon provides a safe, reliable, and lower-operating cost alternative to conventional technologies such as triazine liquid scavengers and iron-based media. Benefits include:
-
Safer Operations: Dry activated carbon eliminates liquid chemical handling while providing thermally stable spent media that simplifies handling and disposal.
-
Reliable performance: High H2S capacity and stable bed life deliver predictable sulfur removal across varying operating conditions without plugging or bricking.
-
Lower Operating Costs: High sulfur loading (>85%), fewer changeouts, and reduced maintenance lower media usage and the total cost of sulfur removal.

Video: H2S Removal With PETRODARCO H2S
PETRODARCO H2S removes H2S from gas safely, effectively, and easily. Our animated video shows how using PETRODARCO H2S in a lead/lag (worker/polisher) vessel configuration optimizes loading capacity, reduces the cost per pound of sulfur removed, and enables maintenance without interruption.
- PETRODARCO H2S, NORIT's flagship H2S removal product, converts H2S to elemental sulfur and sequesters it within the activated carbon's pore network.
- NORIT recommends a lead/lag vessel configuration to maximize loading capacity. This enables H2S loading capacity to exceed 85% by weight, reducing the $/lb of sulfur removed.
- A lead/lag vessel configuration keeps the H2S removal system online during change-outs, with the lag vessel becoming the lead.
- To further optimize PETRODARCO H2S performance, inject a 1:1 O2-to-H2S ratio and maintain relative humidity between 60-100%.
- The lead/lag configuration enables optimal loading rates by slowing the reaction as sulfur adsorption increases.
