Activated Carbon vs. FeO-Based Adsorbents
Dry adsorption using solid media is a proven, simple, and effective technology for flows from tens to thousands of m³/h and moderate H₂S loads. Two dominant adsorbent families are activated carbon (AC) — especially impregnated [...]
Mercaptan Removal from oil and gas
Mercaptans, also known as thiols (RSH), are organosulfur compounds that pose significant challenges in the oil and gas industry. These volatile, odorous impurities occur naturally in crude oil, natural gas, condensates, LPG, and refined products. [...]
Membrane Separation Technology for H2S Removal
Natural gas is a critical energy source, but raw “sour” gas often contains hydrogen sulfide (H₂S), a highly toxic, corrosive, and environmentally harmful impurity. Pipeline specifications typically require H₂S levels below 4 ppm to ensure [...]
Hydrogen Sulfide in the Oil Sands
Hydrogen sulfide (H₂S) is a highly toxic, corrosive, and environmentally challenging gas commonly encountered in the extraction and processing of Alberta’s oil sands. Steam-Assisted Gravity Drainage (SAGD), the dominant in-situ recovery method for deep bitumen [...]
H2S Regulations in Alberta
Alberta’s oil and gas industry is a cornerstone of the provincial economy, but it comes with inherent risks—none more significant than hydrogen sulfide (H₂S), commonly known as sour gas. This colourless, flammable, and highly toxic [...]
Adsorbents for H2S Removal
Pipeline specifications typically require H₂S levels below 4 ppm to prevent corrosion and ensure safety. Among various removal technologies—such as amine scrubbing, membranes, and chemical scavenging—adsorption using solid adsorbents offers a dry-bed, non-regenerative or semi-regenerative [...]
Hydrogen Sulfide management in water treatment
Water treatment facilities—whether municipal drinking water plants treating groundwater or wastewater treatment plants (WWTPs) processing sewage—must implement robust management strategies to control Hydrogen Sulfide. In this comprehensive guide, we explore the origins of H₂S, its [...]
Materials Compatibility of Typical H2S Scavengers
In upstream operations—from drilling and completion through production and gathering systems—H₂S can cause pitting corrosion, stress corrosion cracking (SCC), and sulfide stress cracking (SSC) in pipelines, wellheads, and downhole equipment. To mitigate these issues, operators [...]
Latest Developments in H2S Removal
By 2026, new EPA NSPS/MACT rules, state flaring limits (such as New Mexico’s 98% reduction mandate), and global Best Available Techniques (BAT) requirements are forcing rapid adoption of next-generation H2S removal technologies. This article explores [...]
FeO and Iron Hydroxide-Based Adsorbents
Among the various H₂S removal technologies—such as amine scrubbing, liquid redox processes, and activated carbon—fixed-bed adsorbents based on iron oxide (FeO, Fe₂O₃) and iron hydroxides (Fe(OH)₃, FeOOH) remain popular for their simplicity, reliability, and cost-effectiveness [...]
Price of Typical H2S Scavengers
Operators rely on chemical H2S scavengers—liquid formulations that react with and neutralize H₂S. The most typical and widely used are triazine-based scavengers, particularly monoethanolamine (MEA) triazine (hexahydro-1,3,5-tris(2-hydroxyethyl)-1,3,5-triazine), often supplied as 50–80% active aqueous solutions. Priced [...]
Amine Sweetening Basics
Amine sweetening plants, also known as amine gas treating or acid gas removal units, are critical components in natural gas processing, refinery operations, and petrochemical facilities. These plants remove corrosive and toxic acid gases—primarily hydrogen [...]
