HOW IT WORKS

Oil-Free Reciprocating Piston Compression Principle

The hydrogen booster relies on a crankshaft driven reciprocating piston structure. The motor converts rotational motion into linear reciprocating movement inside hydrogen-resistant precision cylinders. During the suction stroke, the piston moves back to form negative pressure, drawing low-pressure hydrogen produced by methanol reforming systems and hydrogen gas generator devices into the cylinder through inlet check valves.

In the compression stroke, the piston advances to reduce internal volume and lift hydrogen pressure. Pressurised gas is delivered through outlet valves to downstream pipelines or storage tanks for storage and transportation inside green hydrogen plant. All parts touching hydrogen adopt self-lubricating non-metallic sealing materials, which completely isolate lubricating oil from process hydrogen and avoid purity loss. Interstage coolers control exhaust temperature, enabling long-term safe unattended compression operation.

FAQ

What flow range makes reciprocating hydrogen compressor more cost-effective than diaphragm hydrogen compressor for hydrogen production plant?

Reciprocating Hydrogen Compressor delivers better total cost performance for flow rates above 300 Nm³/h within hydrogen production plant. For medium & large hydrogen generation lines matched with methanol reforming, its large single-unit throughput cuts equipment quantity and civil construction investment. Diaphragm Hydrogen Compressor fits small-flow, ultra-high-purity working conditions below 300 Nm³/h, while piston models are the preferred mass boosting equipment for green hydrogen plant projects.

Can oil-free piston hydrogen booster match methanol reforming hydrogen gas generator downstream pressurization?

Yes. This oil-free reciprocating Hydrogen Compressor uses self-lubricating gas path accessories, which will not introduce oil pollution to high-purity hydrogen produced by methanol reforming hydrogen gas generator. It can be directly connected to the PSA outlet pipeline of reforming units to finish medium-pressure boosting for factory pipelines and buffer tank storage.

How many compression stages can be customized to coordinate green hydrogen plant storage tank pressure?

Customers can select 1 to 6 customized compression stages. Our engineering team matches different stage combinations based on inlet hydrogen pressure from hydrogen gas generator and target storage pressure of green hydrogen plant, fully covering 1.0–3.0 MPa medium-pressure boosting requirements for methanol reforming supporting facilities.

What anti-hydrogen embrittlement measures are equipped for long-term continuous operation?

All medium contact components of the Reciprocating Hydrogen Compressor are made of hydrogen-resistant alloy, with special anti-permeation thermal treatment on the inner cylinder wall. Real-time pressure and temperature sensors monitor running status all day long, effectively avoiding hydrogen embrittlement risks under long-duration high-pressure working conditions and supporting round-the-clock stable operation of hydrogen production plant.

Is parallel layout supported to expand throughput of wind solar hybrid system hydrogen station?

Modular parallel operation is fully available. Multiple piston Hydrogen Compressor skids can work synchronously to lift total boosting volume, which perfectly adapts unstable hydrogen output from wind solar hybrid system hydrogen station and realizes flexible flow adjustment following renewable hydrogen production fluctuation.

What’s the difference in daily maintenance cycle between piston and diaphragm Hydrogen Compressor?

Reciprocating Hydrogen Compressor requires monthly inspection on piston rings, packing and valve assemblies, with medium overhaul every 1 to 2 years. Diaphragm Hydrogen Compressor has fewer wearing parts, only quarterly routine inspection is needed, and core diaphragm components need replacement every 3 to 5 years. Piston compressors feature shorter maintenance cycles but cheaper spare parts for long-term green hydrogen plant operation.
