Carbon Monoxide Compressor
Carbon monoxide (CO) is a colorless, odorless, highly toxic, and flammable gas with an explosion limit of 12.5% to 74% in air. Once leaked, it can easily form explosive mixtures over a wide concentration range. At the same time, its strong toxicity demands that the compression system must possess absolute sealing integrity. Therefore, equipment for compressing carbon monoxide must adhere to the highest standards in explosion-proof design, leakage prevention, and material compatibility. Based on its physical and chemical characteristics, we offer two specially designed solutions — diaphragm compressors and piston compressors — capable of meeting diverse requirements ranging from small-flow, high-purity CO for laboratory use to large-scale synthesis gas boosting in industrial processes.
Carbon Monoxide Diaphragm Compressor Advantages:
-
01Absolutely 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.
-
02High 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:
-
01Strict 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.
-
02Triple 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.
-
03Material 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.

Carbon Monoxide Piston Compressor Advantages:
-
01Large Flow & Wide Operating Condition Adaptability:
The piston compressor can deliver a large flow capacity ranging from tens to thousands of cubic meters per minute. Through cylinder configuration and speed adjustment, it can flexibly adapt to different suction and discharge pressure requirements, perfectly matching the large-flow, continuous, and stable compression demands of carbon monoxide gas in large-scale chemical production.
-
02High Reliability & Cost-Effectiveness:
With a robust structure and mature design, its acquisition and maintenance costs are relatively more advantageous. For large-scale industrial projects requiring long-term continuous operation and sensitive to initial investment, the piston compressor provides a proven, high-reliability solution, ensuring stable production line operation and a favorable return on investment.
Key Design Points for Carbon Monoxide Piston Compressors:
-
01Efficient Packing Seal & Nitrogen Protection System:Given the highly toxic and flammable nature of carbon monoxide, the dynamic seal of the piston rod is critical. A multi-stage, high-efficiency packing seal system must be adopted. Clean nitrogen is typically introduced into the packing box as a buffer gas, forming a micro-positive pressure barrier to prevent carbon monoxide from leaking outward along the piston rod. Additionally, the distance piece must be designed with ventilation and purge connections to ensure any potential trace leakage can be safely vented or diluted.
-
02Precise Temperature Control & Oil-Free Lubrication Configuration:The compressor must strictly control the discharge temperature to prevent abnormal temperature rise within the cylinder. By equipping efficient inter-stage and after-coolers, the discharge temperature is typically kept below 150°C or 176°C. For processes with high purity requirements or where oil contamination must be avoided, the cylinders should utilize self-lubricating piston rings and packing made from PTFE or carbon fiber composite materials, achieving oil-free operation within the cylinder and eliminating the risk of oil contamination and carbon build-up.
-
03Comprehensive Safety Monitoring & Explosion-Proof Integration:The electrical system must be equipped with explosion-proof motors and electrical components rated no lower than Ex d IIB T4, based on the explosive characteristics of carbon monoxide. The safety interlock system must be comprehensive, including: high discharge temperature alarms and shutdowns for each stage, low lubricating oil pressure shutdown, low cooling water flow/pressure alarms, and cylinder vibration monitoring. Furthermore, the system must be equipped with inert gas purge piping for removing air before startup and displacing carbon monoxide within the system after shutdown, ensuring operational safety. The safety valve discharge outlets must be connected to a closed flare or recovery system, and must not be vented directly to the atmosphere.
