For CANGAS® cryogenic liquid nitrogen generation plant, the working pressure of the whole plant is less than 0.7Mpa. Operation is simple, flexible and safe while energy consumption is very low.
The process of liquid nitrogen plant includes molecular sieve adsorption towers, gas bearing expander and refrigeration as well as single tower distillation, and so on. We adopt different configurations according to different applications of different nitrogen consumption with different pressure levels at low energy consumption. Certain amount of liquid nitrogen is available at the same time according to customers’ requirements. The production capacity of liquid nitrogen plants could be from 200Nm3/h to 10000Nm3/h @ purity of above 99.999%.
Notes
v The working pressure and nitrogen pressure could be customized on the users’ demand.
v The unit energy consumption of liquid nitrogen production depends on the actual technological process. The power consumption for re-flux process is 0.3kw.h/m3N2. The power consumption for positive flow process is 0.25kw.h/m3N2, and for low pressure twin-tower process, 0.2kw.h/m3N2.
v Production of liquid oxygen is optional as user requirements.
