Preface
As an important foundation of modern industry, air separation technology is widely used in energy, chemical industry, medical treatment, electronics and other fields. With the in-depth development of global industrialization and increasingly stringent environmental protection requirements, the innovation and application of air separation technology and equipment have become the focus of industry attention.
In recent years, air separation technology has achieved a transformation from traditional large-scale to small-scale and high-purity by continuously optimizing process flow and improving equipment efficiency. Especially driven by emerging industries such as new energy and semiconductors, the market demand for high-purity oxygen, nitrogen and other gases has increased significantly. At the same time, the tightening of environmental protection policies has also prompted companies to adopt more efficient and cleaner air separation technology to reduce carbon emissions and energy consumption.
This article will analyze the core principles, quality indicators, process flow, featured products and core advantages of air separation technology, and explore the future development trends of the industry. By combing through the current technical trends and market directions, it provides reference for industry practitioners and related companies.
Technical Introduction: The Core Principle of Air Separation Technology
Air separation technology uses air as raw material, and removes dust, moisture, carbon dioxide and other impurities in the air through purification processes such as filtration, precooling, and molecular sieve adsorption. Then, the purified air is liquefied using compression and expansion technology, and then oxygen, nitrogen and other products are separated through cryogenic distillation technology.
Traditional air separation equipment usually relies on cryogenic compression technology, while modern technology pays more attention to energy efficiency and environmental friendliness. For example, the application of new molecular sieve materials significantly improves adsorption efficiency and reduces energy consumption; the introduction of intelligent control systems further optimizes the production process and reduces human operation errors.
In addition, the application of air separation technology in the medical field is also worthy of attention. High-purity oxygen and liquid oxygen play an irreplaceable role in respiratory therapy, surgical support, etc. With the advancement of medical technology, the requirements for gas purity and stability are also increasing.
Quality indicators and product applications
The product quality of Air Separation Unit is directly related to the effect of downstream applications. According to industry standards, common air separation products and their quality indicators are as follows:
