China Hydrogen Sulfide Compressor Factory: Oil-Free, High-Purity Solutions from Leading Suppliers
Advantages of Hydrogen Sulfide Diaphragm Compressor:
Absolute Sealing and Zero Contamination:
A metal diaphragm is used to completely physically isolate the process gas from the hydraulic oil, forming a static seal. This fundamentally eliminates the risk of toxic gas leaking into the environment and prevents lubricating oil from entering the process system where it could be contaminated by or react with H₂S, ensuring both gas purity and operational safety.
Excellent Resistance to Complex Corrosion:
All flow-wetted components, including the diaphragm head chamber, cover plate, and inlet/outlet valve assemblies, can be specifically constructed from high-grade corrosion-resistant alloys. This allows for a flexible design that effectively addresses electrochemical corrosion, hydrogen permeation, and potentially accompanying Cl⁻ corrosion in wet H₂S environments.
Key Design Points for Hydrogen Sulfide Diaphragm Compressor:
Full Anti-Corrosion Materials for the Diaphragm Head and Flow-Wetted Parts:
Material selection must be strictly in accordance with standards such as SH/T 3096, based on specific H₂S partial pressure, temperature, water content, and Cl⁻ concentration. Typically, 316L stainless steel, with its better pitting resistance and resistance to Cl⁻ stress corrosion cracking due to its molybdenum content, is the preferred basic choice. For extremely harsh conditions, duplex stainless steel or nickel-based alloys must be used. All components should have clearly specified material grades and ensure sufficient corrosion allowance (typically ≥ 2 mm).
Special Material Selection and Monitoring for the Core Diaphragm:
As a critical dynamic component, the diaphragm must simultaneously possess very high fatigue strength, flexibility, and corrosion resistance. Materials like Inconel 718, a high-strength corrosion-resistant alloy, are commonly selected. A diaphragm rupture monitoring and alarm system must be provided. In the event of a pinhole leak or rupture, the system should immediately alarm and trigger a shutdown to prevent oil-gas mixing and safety accidents.
Integrated Safety and Surface Protection Design:
The compressor skid should be integrated with a high-efficiency inlet gas-liquid separator to ensure the gas entering the compressor is as dry as possible, mitigating wet corrosion at the source. All exposed metal parts must undergo professional surface anti-corrosion treatment to resist atmospheric corrosion. The safety valve discharge port must be connected to a closed flare system or caustic scrubber; local venting is strictly prohibited.

Frequently Asked Questions (FAQ)
Q1: Why is a diaphragm compressor preferred for handling Hydrogen Sulfide (H₂S)?
A: A diaphragm compressor uses a metal diaphragm to achieve complete static sealing. This physical isolation prevents toxic and flammable H₂S gas from leaking into the ambient atmosphere or contaminating the hydraulic oil system.
Q2: How does the compressor resist the corrosive nature of wet H₂S?
A: All components that come into contact with the process gas, such as the diaphragm head, cover plates, and valves, are manufactured from high-grade corrosion-resistant materials like 316L stainless steel, duplex stainless steel, or nickel-based alloys.
Q3: What safety measures are in place in case of a diaphragm failure?
A: The compressor is equipped with a diaphragm rupture monitoring and alarm system. If a pinhole leak or rupture occurs, the system immediately triggers a warning and initiates an automatic shutdown to prevent hazardous gas-oil mixing.
Q4: What standards are followed for selecting anti-corrosion materials?
A: Material selection is strictly governed by industrial standards like SH/T 3096, taking into consideration critical variables such as H₂S partial pressure, temperature, water content, and chloride ion (Cl⁻) concentration.
Q5: How is discharge waste gas managed safely?
A: Local venting of toxic H₂S is strictly prohibited. The safety valve discharge ports must be securely connected to a closed flare system or a caustic scrubber system for safe disposal.
