Helium (He) is the second most abundant gas in the entire universe after hydrogen, accounting for 23% by mass. However, helium has extremely low content on Earth, and the oxygen content in the air is only 5 × 10-6, which does not have industrial extraction value. Therefore, extracting ammonia from helium rich natural gas is currently the only method for obtaining ammonia.
The many special properties of helium determine its irreplaceable role in many fields. Helium is the second lightest gas after hydrogen and is non flammable, making it an ideal gas for use as a carrier gas in balloons, airships, and other applications; Helium has the smallest molecular size and can be used for leak detection; Helium has very high specific heat and thermal conductivity, and can be used as a gaseous cooling medium in optical fiber production; Helium has low solubility and can be used as breathing gas for deep-sea diving; Helium has the lowest boiling point and is a necessary medium in the field of low-temperature superconductivity.
Due to its low boiling point and inertness, helium is widely used in the launch engineering of space launch vehicles fueled by liquid hydrogen for safe replacement of pipelines, safe replacement of rocket tanks, pressurization and refueling of rocket tanks during flight, and safe blowing of some low rM mail.
Wuhan Yisi Tuopu Technology Co., Ltd. has introduced advanced gas production technology, analysis, testing and analysis equipment, and quality management concepts from the United States. We have a team of senior experts to support the purity testing of helium gas imported by helium manufacturers. The company's production process and product quality have reached the advanced level in China. Where can I buy helium gas? Consult Wuhan Yisi Tuopu Technology Co., Ltd. for cheaper helium gas.
H S and CO in helium gas source. Impurities such as water and even mercury must be purified before entering low-temperature equipment to prevent blockages, corrosion, and deterioration of process conditions in pipelines, valves, and equipment at low temperatures.
The commonly used acid gas removal methods include alcohol amine method, hot potassium alkali method, and sulfonamide method. Helium extraction process for H. S, CO in natural gas. The residual requirement is: H2s ≤ 4 ppm [1 ppm-M/22.4 (mg/m.), where M is the molecular weight, the same applies below], CO。≤ 100 ppm。 Considering the benefits of helium extraction, a removal method that is conducive to reducing the cost of helium extraction should be preferred.
Dehydration process method: Natural gas helium extraction generally uses molecular sieves for precise dehydration, with a dehydration depth requirement of less than 1 ppm, while further adsorbing and removing residual acidic gases. Mercury removal process method: HgSIV mercury removal molecular sieve can be regenerated and recycled, but the equipment and control are complex; However, sulfur impregnated activated carbon cannot be recycled and needs to be replaced regularly, but the equipment and operation are simple.
After secondary condensation of natural gas, crude helium with a helium content of 6o~7o is produced. The required cooling capacity for condensation is supplied by atmospheric liquid methane, atmospheric liquid nitrogen, or negative pressure liquid methane. The first condensation requires no fraction above ethane, and the second condensation requires a methane content of less than 1. At the same time, the helium content in the kettle liquid hydrocarbon should be less than 10 ppm to improve the helium recovery rate.
The hydrogen in natural gas, which is difficult to liquefy, is concentrated in crude helium with the concentration of helium gas and needs to be removed before refining. Catalytic oxidation dehydrogenation is generally used in industry, and dehydrogenation processes such as hydrogen storage alloys are also developing. Residual hydrogen below 10 ppm is removed simultaneously with nitrogen, small amounts of methane, and other impurities during the subsequent high-pressure condensation adsorption process. The cold source is generally provided by atmospheric liquid nitrogen, which can produce high-purity helium gas with a purity of 99.99 or higher. Other refining methods such as washing absorption can use natural gas components such as methane and propane as absorbents.
