High purity Small Liquid Nitrogen Equipment can use forward and reverse flow; Multiple process organization methods such as single tower and double tower are used to meet customers' different pressure level requirements. The entire device can adopt DCS or PLC system
Control. Air compression: Air filtered by a filter to remove mechanical impurities enters the air compressor and is compressed to the required pressure.
Air pre cooling: It is cooled to the appropriate temperature in the pre cooling system while separating free water. Air separation purification: The adsorbent removes water, carbon dioxide, and other hydrocarbons in the adsorber.
Fractionation tower cold box: Clean air enters the cold box and is cooled to near liquefaction temperature through a heat exchanger before entering the distillation tower. exist
The upper part obtains product nitrogen, and the lower part obtains product oxygen.
