Micro-Temperature Technology's all-liquid air separation unit features an advanced and rational process configuration. It not only ensures long-term stable operation but also achieves substantial liquefaction capacity with low energy consumption. The current implementation employs booster turbine expanders and circulating compressors, offering compact dimensions, fewer units, high efficiency, and reduced costs. Simultaneously, it delivers enhanced operational stability, safety, and reliability, enabling unmanned operation.

The trend towards larger-scale air separation equipment has become established within the industry. Driven by China's carbon neutrality policies, stricter carbon emission controls are compelling industrial enterprises to replace outdated machinery with large-scale and extra-large units featuring lower energy consumption per unit output. According to calculations by the China Industrial Gases Association, specialised large-scale air separation units producing over 5000Nm³/h of oxygen exhibit lower energy consumption per unit of production than smaller installations.
Micron specialises in the R&D of large-scale air separation equipment, employing the most advanced processes and technologies: high-efficiency compressors, molecular sieve pre-purification, structured packing technology, hydrogen-free argon production, internet-based remote monitoring, low-pressure distillation energy-saving techniques, and large-scale cryogenic liquid storage. We have now achieved complete skid-mounted integration for ultra-large and large air separation units.

The high-purity nitrogen purification unit employs a reflux collision pressurisation process, yielding substantial liquid output while achieving gas purity levels below 1 ppm O₂. Production remains stable throughout operation. This system not only generates high-purity nitrogen but also produces oxygen-enriched gas and liquid nitrogen, featuring low energy consumption and relatively modest capital investment.

The micrometre-scale compact air separation unit employs state-of-the-art air separation processes and technologies, high-efficiency compressors, molecular sieve pre-purification techniques, structured packing technology, hydrogen-free argon production methods, internet-based remote monitoring systems, and low-pressure distillation energy-saving technologies to produce gas of exceptional purity. Micrometer's air separation units are produced as fully integrated skid-mounted systems, offering rapid start-up, stable operation, low costs, compact footprint, short delivery cycles, and modular supply capabilities. They can also produce liquid nitrogen for nitrogen storage and peak shaving applications.

The micrometre compact cylinder filling oxygen generation equipment employs standardised and modular design principles, ensuring significantly reduced engineering, installation, operational and maintenance costs for on-site gas supply systems whilst offering exceptional flexibility. Different systems and system modules can be combined as required to deliver bespoke solutions, meeting diverse industrial gas requirements. By optimising the design of on-site gas supply installations and backup systems, capital expenditure, operational costs and utility consumption – including electricity and water – can be minimised.
