The pretreatment process varies according to the gas source entering the PSA magazine, the pretreatment of a single impurity source is relatively simple and can be solved by separation or removal or re-removal
With the development of metallurgical industry, the enterprise produces all kinds of high quality and high quality carbon structural steel, alloy structural steel, seamless steel pipe and building materials. Due to the need of production, the enterprise cooperates with DEAR air separation on type 16000/20000-520 project, this solution is through multistage rectification. the characteristics of hydrogen-free argon production process solve the specific needs of enterprises.
DEAR air separation has provided several sets of air separation equipment for the metallurgical industry for many years, and has accumulated rich experience. The equipment is operated safely and stably, adopting the whole low pressure process of molecular sieve adsorption and turbine expansion machine refrigeration
What are the requirements for selecting materials for high purity nitrogen gas distribution pipelines in small air separation unit?
High purity nitrogen gas has to be transported through pipelines to the point of use of the small air separation unit. In order to meet the quality requirements of the gas for the process, the selection of materials for the piping system and the quality of construction need to be paid more attention to during the construction process, provided that the gas ...
The adsorbent can adsorb and desorb small molecules such as H, N2.CH, C0. C02.02 etc. under operating conditions, but it is difficult to desorb liquid, sulphide and many large molecules such as high hydrocarbons (Cs+), tar, naphthalene, benzene etc. after adsorption. These substances are equivalent to 'toxic substances' for the adsorbent, once the adsorbent is adsorbed the adsorbent will not be able to desorb and regenerate in time, or cannot be completely desorbed, the adsorbent will lose its a...
