1. General Reaction Principle Mercaptan scavengers work by chemically reacting with mercaptan groups (R–SH) to transform odorous, corrosive, reactive mercaptans into stable, odorless, non‑corrosive products. The core target is the thiol group (–SH). Main reaction pathways: 2. Reaction Mechanism of Triazine-Based Scavengers Triazines are the most widely used water‑soluble mercaptan scavengers, typically based on hexahydro‑1,3,5‑tris(hydroxyethyl)triazine (HET Triazine).

In oil and gas production, mercaptan scavengers work by chemically converting odorous and corrosive mercaptans into harmless, odorless compounds, thereby fundamentally eliminating odor, reducing toxicity, and mitigating corrosion risks. The technical principles are primarily based on the following types of chemical reactions, depending on the type of scavenger used: ⚙️ Read more
Summary:This article provides an overview of mercaptan scavengers—chemical additives used to remove mercaptans from hydrocarbon streams. It describes two main technology categories: liquid chemical scavengers (e.g., triazines, quaternary ammonium salts, and non-nitrogen formulations) and solid adsorbent materials (e.g., iron-based media). Their mechanisms, typical applications, and selection considerations are summarized, highlighting Read more
Introduction Volatile Organic Compounds (VOCs) are organic chemicals that easily vaporize at room temperature and are widely present in industrial production processes. Common VOCs include benzene, toluene, formaldehyde, and various solvents emitted from chemical manufacturing, coating operations, printing industries, and petrochemical facilities. These compounds not only contribute to environmental problems Read more
