The purpose of purification system of air separation equipment is to remove water, carbon dioxide and hydrocarbons and other impurities in the air through molecular sieve, so as to guarantee the safe operation of air separation device. The water content in the air purified by molecular sieve adsorber is ≤5PPm, carbon dioxide ≤1PPm.
The main component of molecular sieve is alkaline silica-aluminate, which has certain crystalline and connecting structure and can make some specific molecules pass through the substance. Liquefaction equipment usually has a pre-purification device for purifying process air, and two molecular sieve adsorbers (one adsorption, one regeneration) are used alternately to ensure the continuity of its work. The purpose is to remove moisture and carbon dioxide and hydrocarbons from the air (the average content of carbon dioxide in the air is about 500 ppm).
DEAR air separation equipment production technology is mature and standardised, the technology is strictly controlled, the equipment is safe and high-quality, to ensure the production of safe operation and maintenance, stable and efficient operation.
