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.
