Advantages of Hydrogen Sulfide Diaphragm Compressor
01
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.
02
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
01
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).
02
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.
03
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
Why is a diaphragm compressor preferred for handling Hydrogen Sulfide (H₂S)?
Diaphragm compressors utilize a metal diaphragm to form a static, physical seal between the gas chamber and the hydraulic system. This design completely eliminates dynamic seals, preventing the leakage of toxic H₂S gas into the environment and protecting operators and surrounding equipment.
What materials are used to prevent H₂S corrosion in your compressors?
All flow-wetted components are made from high-grade corrosion-resistant alloys matching SH/T 3096 standards. Typical selections include 316L stainless steel, duplex stainless steel, or nickel-based alloys like Inconel 718 for the core diaphragms to resist stress corrosion cracking and hydrogen embrittlement.
How does the diaphragm rupture monitoring system protect the operation?
The compressor features a double or triple-layer diaphragm structure. If any layer develops a pinhole or ruptures, the integrated monitoring system detects the pressure change between layers immediately, triggering an automatic alarm and system shutdown to prevent toxic gas from mixing with hydraulic oil.
Can these compressors handle wet hydrogen sulfide gas?
Yes. To mitigate wet H₂S corrosion, the systems are designed with high-efficiency inlet gas-liquid separators to dry the gas before compression. Additionally, special material grades with sufficient corrosion allowance (typically ≥ 2 mm) are utilized for wet gas conditions.
Are custom flow rates and pressure configurations available?
Absolutely. Depending on the model series selected (GZ, GV, GL, GD), we offer customized solutions supporting discharge pressures up to 100Mpa and flow rates ranging from 1 to 2000Nm³/h to match specific industrial requirements.
