Liquid air separation plant in medical and industrial applications
Professional liquid air separation plant manufacturer
1. Industrial gas production
In the field of industrial gas production, the gas cryogenic air separation unit plays a vital role. The oxygen, nitrogen and argon produced by it are widely used in many industries such as steel, chemical, and electronics, and play a key role in the production process and product quality of various industries.
In the steel industry, oxygen is an indispensable and important gas in the steel smelting process. In converter steelmaking, high-purity oxygen is blown into the converter as an oxidant, and violent oxidation reactions occur with impurities such as carbon, silicon, and manganese in the molten iron. These oxidation reactions not only generate a large amount of heat, providing the required high-temperature environment for the steelmaking process, but also speed up the removal of impurities and significantly improve steelmaking efficiency.
For example, in the converter steelmaking workshop of the steel enterprise we cooperate with, a large amount of oxygen is consumed every hour. The high-purity oxygen provided by the gas cryogenic air separation unit shortens the steelmaking time from the original 3 hours to 2 hours each time, greatly improving production efficiency. At the same time, the participation of oxygen reduces the impurity content in the molten steel, improves the purity and quality of the steel, and produces steel with better strength and toughness, meeting the demand for high-quality steel in industries such as construction and machinery manufacturing.
2. Medical applications
In the medical field, liquid oxygen and liquid nitrogen produced by gas cryogenic air separation devices play an indispensable and key role. They are widely used in important medical scenarios such as operating rooms, emergency centers, and intensive care units, providing strong protection for the life and health of patients.
In emergency centers, liquid oxygen is a key material for saving lives. For patients with critical illnesses such as respiratory failure, acute myocardial infarction, and severe trauma, timely oxygen supplementation is one of the key factors for successful rescue. Liquid oxygen can quickly increase the patient's blood oxygen saturation, relieve hypoxia symptoms, and buy precious time for subsequent treatment. In a certain area, an average of 10-15 patients who need emergency oxygen therapy are received every day in an emergency center. The stable supply of liquid oxygen enables these patients to receive effective treatment in the shortest time, greatly improving the success rate of emergency treatment.
Liquid nitrogen is also widely used in the medical field. In terms of medical cryopreservation, liquid nitrogen has become an ideal medium for preserving biological samples, tissues and organs due to its extremely low temperature (boiling point is -196°C). In the field of reproductive medicine, reproductive cells such as sperm, eggs and embryos need to be stored at extremely low temperatures to maintain their activity and function. Liquid nitrogen storage tanks can provide a stable low-temperature environment to ensure the quality and safety of reproductive cells during long-term storage. A reproductive medicine center uses liquid nitrogen cryopreservation technology to successfully preserve thousands of sperm and egg samples, making it possible for many infertile couples to realize their dream of having children. In stem cell research and applications, the preservation of stem cells is also inseparable from the support of liquid nitrogen. Stem cells have the ability to self-renew and differentiate, and have broad application prospects in disease treatment and regenerative medicine. Storing stem cells in liquid nitrogen can effectively maintain their biological characteristics and functions, providing guarantees for subsequent research and clinical applications.
