Advantages of Hydrogen Sulfide Diaphragm Compressor
-
01Absolute Sealing and Zero ContaminationA 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.
-
02Excellent Resistance to Complex CorrosionAll 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
-
01Full Anti-Corrosion MaterialsMaterial 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).
-
02Special Material Selection & MonitoringAs 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.
-
03Integrated Safety & Surface ProtectionThe 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 ideal for handling Hydrogen Sulfide (H₂S)?
A diaphragm compressor uses a metal diaphragm to isolate the gas chamber physically from the hydraulic drive system. This static seal construction ensures zero external leakage of toxic H₂S, protecting the environment and operators, while avoiding any contamination of the process gas by lubricating oils.
How do you prevent corrosion caused by H₂S in wet environments?
We construct all flow-wetted components (diaphragm heads, valve plates, and piping) from high-grade anti-corrosive alloys such as 316L stainless steel, duplex stainless steel, or nickel-based alloys like Inconel 718. The materials are selected in strict accordance with industry standards such as SH/T 3096 to prevent chloride pitting and stress corrosion cracking.
What happens if a diaphragm ruptures during compressor operation?
Our compressors are equipped with a continuous diaphragm rupture monitoring and alarm system. If a pinhole leak or crack occurs, the system immediately detects the pressure change, triggers a control system alarm, and safely shuts down the unit to prevent gas-oil mixing or toxic release.
Are these compressors suitable for sour gas injection or recovery?
Yes, our diaphragm compressors are highly suited for sour gas (high H₂S content) recovery, chemical processing, and injection applications due to their high-pressure capabilities, corrosion-resistant build, and leak-proof design.
What cooling methods are available for these compressors?
Depending on the model, size, and operational environment, we offer both water-cooled and air-cooled configurations to maintain optimal thermal efficiency and safety during continuous operations.
