Carbon Monoxide Compressor from China Suppliers - High-Strength, Oil-Free, and Safe Factory Equipment
Carbon Monoxide Diaphragm Compressor Advantages
01
Absolutely Oil-Free & Zero Leakage Safety Assurance
The metal diaphragm completely physically isolates the process gas from the hydraulic oil and the external environment, achieving 100% oil-free lubrication during compression and thoroughly eliminating the risk of reaction between lubricating oil and carbon monoxide under high temperature. The static seal structure ensures zero external leakage of the gas, fundamentally resolving the safety and environmental hazards caused by toxic gas leakage, and perfectly matching the stringent sealing requirements for carbon monoxide.
02
High Purity Retention & Anti-Contamination Design
The compression chamber is completely independent with a high surface finish. The gas only contacts specially treated wetted parts, with no contamination from wear of internal moving parts. This allows the initial purity of the carbon monoxide gas to be maintained stably over the long term, meeting the raw gas purity requirements for high-end chemical synthesis.
Key Design Points for Carbon Monoxide Diaphragm Compressors
01
Strict Temperature Monitoring & Over-Temperature Prevention Design
The minimum auto-ignition temperature of carbon monoxide in air is 588°C. Although its auto-ignition temperature is relatively high, temperature must still be strictly controlled during compressor operation. The equipment must be configured with multi-stage compression and an efficient inter-stage cooling system to ensure that the discharge temperature at each stage is far below the safety threshold. High discharge temperature alarms and a high-high temperature shutdown interlock must be provided to prevent temperature accumulation due to cooling failure or abnormal operating conditions.
02
Triple Leakage Protection & Safety Interlock System
Diaphragm Rupture Monitoring:
A three-layer diaphragm design is adopted, equipped with a diaphragm rupture alarm device. Once the gas-side diaphragm ruptures, the pressure change in the middle layer immediately triggers a pressure switch, issuing an audible and visual alarm and interlocking an emergency shutdown of the compressor to prevent gas from entering the oil circuit or the external environment.
Comprehensive Safety Interlocks:
In addition to diaphragm monitoring, the system must integrate multi-parameter safety interlocks including low suction pressure, high discharge pressure, low lubricating oil pressure, and cooling water failure. Upon any abnormality, the control system will immediately execute a shutdown procedure to ensure the system remains in a safe state.
03
Material Compatibility & Special Treatment
All wetted parts in contact with carbon monoxide, including the diaphragm, cylinder head, valve seats, etc., must be made of corrosion-resistant high-quality stainless steel (e.g., 316L). During manufacturing, thorough degreasing, cleaning, and passivation treatment must be carried out to remove surface oils and impurities, preventing catalytic reactions with carbon monoxide or contamination. For operating conditions that may involve wet carbon monoxide (containing water), the necessity of upgrading to a higher-grade corrosion-resistant alloy must be evaluated to prevent the formation of corrosive acids.

Frequently Asked Questions (FAQ)
Q:
Why is zero leakage critical for Carbon Monoxide (CO) compressors?
Carbon monoxide is a highly toxic, flammable, and hazardous gas. Any external leakage poses severe risks to human health and environmental safety. Diaphragm compressors utilize a static sealing structure that completely isolates the gas from the external atmosphere, ensuring absolute containment and zero leakage.
Q:
How does the triple-layer diaphragm design protect the system from failure?
The triple-layer metal diaphragm isolates the process gas from the hydraulic oil. If any layer ruptures, the inter-layer pressure sensor instantly detects the pressure change and triggers an automatic emergency shutdown, preventing gas contamination or leakage into the environment.
Q:
Why is stainless steel 316L preferred for wetted parts in CO compressors?
Stainless steel 316L offers excellent corrosion resistance and compatibility with carbon monoxide. To prevent catalytic reactions or contamination under high pressure and temperature, all wetted parts undergo special degreasing, cleaning, and passivation treatments.
Q:
What cooling methods are available for these compressors?
Depending on the model and operating conditions, both water-cooled and air-cooled options are available. Efficient inter-stage cooling is vital to keep discharge temperatures far below the safety limits, preventing any risk of thermal accumulation.
Q:
Can these compressors handle wet carbon monoxide gas?
Yes, but wet carbon monoxide can form corrosive acids. For such operating conditions, the material specifications of the wetted parts must be evaluated and upgraded to higher-grade corrosion-resistant alloys to ensure long-term durability.
