Ultrapure Helium Since the purification process for ultrapure helium is similar to that for ultrapure hydrogen, similar equipment and processes can be used to produce ultrapure helium. Specifically, the production process of ultrapure helium mainly consists of the following steps:
First, helium is extracted from natural gas or oil. Helium is usually extracted along with natural gas or oil, so it needs to be separated from other gases by specific separation techniques.
Secondly, the extracted helium is purified. This process can be achieved through technologies such as low-temperature adsorption, chromatographic separation, and membrane separation. These technologies can remove impurities from helium to very low levels, resulting in high-purity helium.
The third step is compression and liquefaction. In order to facilitate storage and transportation, the purified helium needs to be compressed and liquefied. This process can be achieved using a compressor and liquid nitrogen coolant.
The final step is storage and transportation. Liquefied helium needs to be stored at low temperatures to ensure its purity and stability. At the same time, it needs to be delivered to the end user for ease of use. This process requires the use of specialized pipes and vessels to ensure the safety and purity of helium.
Throughout the production process, attention needs to be paid to controlling parameters such as temperature, pressure, flow rate, etc., to ensure the quality and safety of the helium produced. In addition, the waste generated during the production process needs to be properly disposed of to avoid environmental impact.
In summary, the production process of ultrapure helium requires multiple steps, including extraction, purification, compression, liquefaction, and storage. In order to ensure the quality and safety of the helium produced, the parameters and equipment conditions in the production process need to be strictly controlled, and the waste generated needs to be properly disposed of. As the application fields of ultrapure helium continue to expand, the production technology of ultrapure helium also needs to be constantly developed and innovated to meet the needs of the market.
