This plant operates on a low pressure cycle and is used to produce pure oxygen and
nitrogen from air by means of cryogenic rectification.The feed air is first liquified
by the refrigeration  produced by turbo-expander and then rectified for
two times on the basis of the different boiling points between liquid oxygen and
liquid nitrogen. As a result, oxygen at a purity of over 99.6% and nitrogen at
a purity of over 99.99% can be obtained from the plant. If required, the plant can
also produce liquid oxygen and liquid nitrogen partially by means of modified
operation.

We can also design and produce it with different capacities for you.
