Membrane Nitrogen Plants
One of the primary types of Nitrogen plant is designed on the basis of the Membrane air separation technology.
If 99.95% pure gaseous Nitrogen is required where capacity rate does not exceed 1500 nm³/hr, or lower-purity Nitrogen at a higher capacity rate of up to 5000 nm³/hr, membrane air separation technology appears to be the most suitable option. Considering the economic performance, most economically sound is the use of air separation plants for nitrogen generation designed on the basis of hollow-fiber polymer membranes.
Membrane nitrogen plants has the broadest application in nearly all areas of human activities where high nitrogen purity (above 99.95%) is not a critical requirement. In fact, the major part of nitrogen applications is determined by its inert properties.
Application:
- Petroleum industry
- Chemical
- Petrochemical
- Metallurgical
- Food facilities and others.
Adsorption nitrogen plants are capable for nitrogen production with the purity of up to 99.9995%.
Adsorption nitrogen plants complete the membrane-based air separation, allowing to recover nitrogen with the purity in excess of 99.95% - the maximum achievable purity ensured by the membrane method. Adsorption nitrogen plants operating mechanism is based on the principle of air mixture separation into nitrogen and oxygen with the help of adsorbing materials. While oxygen is retained by the adsorbent, nitrogen passes through freely.
The key advantages delivered by adsorption nitrogen plants include low energy consumption, and consequently, low nitrogen net cost, as well as high reliability and simplicity of control and operation as well.
Adsorption nitrogen plants are suited for a broad range of applications, especially for the ones where fairly high nitrogen purity is required.
Application:
- Chemical
- Petrochemical
- Petroleum industries
- Food
- Pharmaceutical industries among others.
Cryogenic nitrogen plants represent highly efficient equipment for large-scale nitrogen production with the nitrogen purity of up to 1 ppm.
Wherever the customer requires above 99.999% pure nitrogen with nitrogen consumption volume exceeding 5000 nm³/hr, then in most cases economically feasible proves the cryogenic technology of nitrogen production. Where nitrogen consumption is rated to more than 10000 nm³/hr, cryogenic technology-based plants are nearly always more advantageous than membrane and adsorption systems for production of nitrogen.
Apart from these features, where the customer requires nitrogen generation in both gaseous and liquid state, cryogenic technology is the only adequate choice. Liquid air separation products may be generated only by means of low-temperature rectification, while membrane and adsorption nitrogen plants are only useful for production of gaseous-state products.
