Hydrogen Sulfide Compressor from China Suppliers – High-Purity, Oil-Free Technology from Leading Factory
Advantages of Hydrogen Sulfide Diaphragm Compressor:
-
01Absolute 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.
-
02Excellent 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:
-
01Full 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).
-
02Special 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.
-
03Integrated 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)
Diaphragm compressors utilize a metal diaphragm to achieve a complete static physical isolation between the process gas and the hydraulic oil. This absolute sealing eliminates toxic gas leakage into the environment and protects the gas from oil contamination, making it the safest option for highly toxic and corrosive H₂S gas.
All flow-wetted components are constructed from high-grade corrosion-resistant alloys. Standard designs use 316L stainless steel (compliant with SH/T 3096 guidelines) for basic protection, while extremely harsh conditions require duplex stainless steel or nickel-based alloys like Inconel 718 to resist electrochemical corrosion and hydrogen embrittlement.
The compressor is equipped with a continuous monitoring and alarm system. If a pinhole leak or rupture occurs in the core metal diaphragm, the system immediately senses the pressure change, triggers an alarm, and automatically initiates a safety shutdown to prevent oil-gas mixing and safety hazards.
Yes. An integrated high-efficiency inlet gas-liquid separator is used to dry the gas as much as possible before compression. Removing liquid moisture mitigates wet H₂S corrosion and prevents liquid slugging, which could damage the compressor head.
For safety and environmental protection, the safety valve discharge port must be connected directly to a closed flare system or a caustic scrubber. Local atmospheric venting of toxic hydrogen sulfide gas is strictly prohibited.
