* Large-scale production capacity: It is suitable for large-scale industrial production and can meet the demand for a large
amount of gas. Its production capacity can be designed and adjusted according to user needs, ranging from several hundred cubic
meters per hour to tens of thousands of cubic meters per hour, which can effectively ensure the continuous and stable
production of large industrial enterprises such as metallurgy and chemical industry.24.
* Continuous and stable operation: After reasonable design and optimization, the low-temperature air separation unit can achieve
long-term continuous and stable operation. Usually, the annual operation time can reach more than 8000 hours, reducing
production interruptions caused by equipment failures or maintenance and improving production efficiency.
Safety and reliability aspect
* High system safety: Operating in a low-temperature environment reduces the risk of fire and explosion. Compared with some
methods that use high temperatures or chemical reactions to separate gases, there are no dangerous reactions such as combustion
and oxidation in the low-temperature air separation process, reducing safety hazards. Especially when handling oxygen and other
combustible gases, the safety is even more prominent.34.
* Strong equipment reliability: The main equipment in the low-temperature air separation unit, such as compressors, expanders,
and distillation towers, has high reliability and stability after years of technological development and improvement. These
equipment usually adopt high-quality materials and advanced manufacturing processes and can operate stably for a long time
under harsh working conditions, reducing the impact of equipment failures on production.
Energy consumption and cost aspect
* Relatively low energy consumption: Although the operation of the low-temperature air separation unit requires a certain amount
of energy to achieve processes such as air compression, cooling, and distillation, compared with some other gas separation
methods, its energy consumption is relatively low. By adopting advanced energy-saving technologies and optimized process flows,
such as high-efficiency heat exchangers, energy-saving compressors and expanders, the energy consumption of the unit can be
further reduced and production costs can be lowered.4.
* Stable operation cost: Since the main consumptions of the low-temperature air separation unit are electricity and cooling
water, etc., the prices of these energies are relatively stable, so the operation cost of the unit is also relatively stable.
Compared with some gas separation methods that use chemical agents or adsorbents, there is no need to frequently replace
consumables, reducing the fluctuation of operation costs.
Environmentally friendly aspect
* No pollutant discharge: During normal operation, the low-temperature air separation unit does not produce pollutants such as
waste water, waste gas, and waste residue, and is not polluting to the environment. Its separation process is mainly based on
physical changes and does not involve chemical reactions, so it does not produce harmful gas or chemical substance emissions
and meets environmental protection requirements.
* Resource recycling: It can effectively recycle and utilize various components in the air to maximize the utilization of
resources. For example, recycling the rare gases in the waste gas generated during the production process can not only improve
the utilization rate of resources but also reduce the impact on the environment.
