Helium Plant
Overview
The Helium Plant is a fully integrated industrial system designed to extract, purify, and compress helium from various feed gas sources for storage and distribution.
Working principle
| Stage | Process | Key Function | Typical Output |
|---|---|---|---|
| 01 | Raw Gas Compression | Compresses helium-containing feed gas to a stable operating pressure for downstream processing. | Gas pressure increased to 1.0–3.0 MPa |
| 02 | Pre-Treatment | Removes moisture, CO₂, H₂S, and heavy hydrocarbons to protect equipment and stabilize purification efficiency. | Cleaned process gas ready for separation |
| 03 | Primary Separation | Separates helium from methane and other major gases using cryogenic or adsorption technology. | Crude helium with 50%–90% purity |
| 04 | Deep Purification | Eliminates trace impurities such as hydrogen, nitrogen, and oxygen through catalytic oxidation and adsorption processes. | High-purity helium exceeding 99.999% purity |
| 05 | Helium Liquefaction (Optional) | Cools purified helium to cryogenic temperature for liquid helium production and storage. | Liquid helium at approximately −268.9 °C |
| 06 | Product Delivery | Supplies helium in gaseous or liquid form based on end-user requirements. | Compressed gas cylinders or cryogenic liquid storage |
Helium Plant Core Features
Ultra-high purity
It can stably produce helium with a purity of over 99.999%, and can reach 99.9999% under special configurations, meeting the needs of high-precision fields such as semiconductors and aerospace.
01
Stability
Once started and running stably, it can produce helium continuously for a long time, with a typical operating cycle of 2-4 years (requiring regular shutdown maintenance).
02
Effective utilization of raw materials
While extracting helium, other useful components in the raw material gas (such as natural gas) can be recovered and utilized, improving the comprehensive utilization rate of resources.
03
Complex start-up process
Due to the need for system cooling, adsorbent activation, and other processes, the start-up time is relatively long, usually taking 24-72 hours to reach standard gas production (small equipment can be shortened to 12-24 hours).
