Description
Hydrogen Sulfide Reactor

Nace MR0175/ISO 15156. Section VIII, Div. 1 or 2 API 650/620

Hydrogen sulfide (H₂S) reactor is a specialized vessel designed to process, remove, or convert H₂S—a toxic, corrosive, and flammable gas commonly found in natural gas, refinery streams, biogas, and chemical processes. These reactors are crucial in gas sweetening, sulfur recovery (Claus process), and wastewater treatment.

Below is a detailed breakdown of the composition and key components of an H₂S reactor:

Main Structure Material Selection for Shell & Heads:
  • Stainless steel (316L, 2205 duplex) – Resists H₂S-induced stress corrosion cracking (SSC).
  • Nickel alloys (Inconel 625, Hastelloy C-276) – For high-temperature/pressure applications.
  • Carbon steel with internal lining (e.g., glass-reinforced epoxy (GRE), rubber lining) for cost-effective solutions.
Compliance Standards:
  • NACE MR0175/ISO 15156 (for H₂S service).
Design Features
  • Cylindrical, vertical/horizontal orientation.
  • Pressure rating: Typically 5–100 bar, depending on process (e.g., Claus reactors operate at ~1–5 bar).
  • Temperature range: 50–600°C (Claus reactors run at ~200–350°C).
Types of H₂S Reactors & Their Applications
Reactor Type Process Application
Claus Reactor Catalytic conversion Sulfur recovery (oil & gas plants)
Direct Oxidation H₂S → S (LO-CAT, Sulfatreat) Biogas, small-scale treatment
Amine Scrubber Absorption (H₂S → amine) Natural gas sweetening
Biological Reactor Microbial oxidation (Thiobacillus) Wastewater treatment
H₂S-Specific Material & Corrosion Standards

Since H₂S causes sulfide stress cracking (SSC) and hydrogen-induced cracking (HIC), these standards dictate material selection:

  • NACE MR0175 / ISO 15156
    • Defines acceptable materials for sour service (H₂S-containing environments).
    • Requires:
      • Hardness limits (e.g., ≤ 22 HRC for carbon steel).
      • Sulfur content control in steels.
  • NACE TM0284 (HIC Testing)
    • Evaluates resistance to hydrogen blistering in steels.
  • NACE TM0177 (SSC Testing)
    • Tests materials under tensile stress in H₂S environments.
