Product Description
Medical Oxygen Plant 1000Nm3/H With Low-Energy Consumption High-Purity
The basic principle of air separation is use cryogenic rectification to condense air into liquid and separate the air according to the evaporation temperature of each component. The two-stage rectification tower simultaneously obtains pure nitrogen and pure oxygen at the top and bottom of the upper tower. It is also possible to take out liquid oxygen and liquid nitrogen from the evaporation side and the condensation side of the main cooling respectively. The air separation in the rectification tower is divided into two stages, air is separated for the first time in the lower tower to obtain liquid nitrogen and at the same time obtain oxygen-enriched liquid air. The oxygen-enriched liquid air is sent to the upper tower for rectification to obtain pure oxygen and pure nitrogen. The upper tower is divided into two sections: with the liquid-air inlet as the boundary, the upper part is the rectification section, which rectifies the rising gas, recovers the oxygen component,and purifies the nitrogen purity, and the lower section is the stripping section to remove the nitrogen components in the liquid, separated to improve the oxygen purity of the liquid

Q5: What is the difference of PSA and Cryogenic plant to produce Oxygen/Nitrogen??
A: . Adsorption method Let the air pass through the molecular sieve adsorption tower, and use the molecular sieve to selectively
adsorb the oxygen and nitrogen components in the air to separate the air to obtain oxygen.
. Cryogenic rectification (cryogenic
air separation plant) The air is compressed and cooled to make the air saturated and liquefied, and the oxygen and nitrogen are
separated by means of rectification by utilizing the difference in the boiling points of the oxygen and nitrogen components, so as
to obtain oxygen and nitrogen with high purity. Cryogenic method is a combination of cryogenic and rectification. It is the most
widely used air separation method at present and occupies a dominant position in the oxygen production industry at home and
abroad.
