On May 12, a tank truck fully loaded with high-purity helium slowly drove out of the LNG plant of the Liquefied Natural Gas Company affiliated to the Gas Group, marking the official delivery of the first truckload of high-purity helium from the BOG helium extraction unit to customers. This not only achieves a major breakthrough for the Liquefied Natural Gas Company in the field of strategic resource development but also marks the full launch of large-scale high-purity helium export business.

 

At the filling site, the silver-white transport bundle truck and the fluctuating process parameters in the central control room complement each other. As the valve opens, high-purity helium is precisely injected into the truck's bundle along special alloy pipelines. On-site technicians closely monitor the instrument panel and carefully verify each set of data to ensure the filling process is safe, precise, and efficient. According to the head of the Production and Operation Department, the company's helium extraction project is a direct extension of the existing LNG plant's production, adopting a combined process technology of membrane separation and pressure swing adsorption to extract high-purity helium from BOG flash gas. Through processes such as catalytic dehydrogenation, rough helium extraction, and refining, it produces high-purity helium meeting national standards in a low-temperature environment of around -200 degrees Celsius.

 

The successful delivery of the first truckload of helium marks a new starting point for technological breakthroughs and industrial development. In the future, the company will continue to optimize production processes, continuously improve product quality, and supply the market with higher-quality and more stable high-purity helium. Meanwhile, it will continue to explore the extension and expansion of the helium industry chain, promote the diversified development of the helium industry, and contribute more wisdom and strength to safeguarding national energy security and driving the vigorous development of high-tech industries.
