    Working Principle

    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.

    PROCESS FLOW

    A2

    1、Air Compressor: Air be compressed to 0.5-0.7Mpa by air compressor

    2Pre-cooling: The air is pre-cooled to 5-10in the pre-cooling unit, and the moisture is separated.

    3Air purification systemRemoving the remained moisture, carbon dioxide and hydrocarbons of compressed air in the molecular sieve purifier;

    4Air expansionThe air expands and cools in the turbo expander and provides the cooling capacity required by the device

    5Heat ExchangeThe air exchanges heat with the refluxing oxygen, nitrogen, and dirty nitrogen in the heat exchanger of the fractionation tower, and is cooled close to the liquefaction temperature, and the refluxed oxygen, nitrogen, and dirty nitrogen are repeatedly heat exchanged to the ambient temperature;

    6CoolingCooling the liquid air and liquid nitrogen before the throttling of the nitrogen in the chiller.

    7DistillationThe air is rectified and separated in the rectification tower, and the product nitrogen is obtained at the top of the upper tower, and the product oxygen is obtained at the bottom of the upper tower.

    Technology

    1.Air Separation Unit with normal temperature molecular sieves purification, booster-turbo expander, low-pressure rectification column, and argon extraction system according to client’s requirement.

    2.According to the product requirement, external compression,internal compression (air boost,nitrogen boost),self- pressurization and other processes can be offered.

    3.Blocking structure design of ASU, quick installation on site.

    4.Extra low pressure process of ASU which reduce air compressor exhaust pressure and operation cost.

    5.Advanced argon extraction process and higher argon extraction rate.
