CRYOSSNitrogen generation plants based onthe cryogenic process
ECOVAR supply systems enable on-site production of industrial gases. The CRYOSS
product line is part of the Linde ECOVAR portfolio. The standardized and modularizedset-up assures maximum cost efficiencies and reliability. Linde puts emphasis on applyingstate-of-the-art technology and maximized flexibility for customized solutions. AllECOVAR systems include a back-up unit to ensure continuous supply.
CRYOSS plants are highly compact and modular. This enables easy transport and rapidinstallation. All parts are fully pre-engineered to accelerate delivery and start-up. A unittypically consists of two factory assembled modules, the warm end container and a cold-box. The container is usually equipped with an air compressor, an air pre-treatment unit,a control system and electrical devices. The coldbox mainly contains heat exchangers, acondenser and the rectification column. CRYOSS plants are modularized in 7 size rangesresulting in more than 20 specific plant sizes.

The cryogenic process separates air by means of rectification, which utilizes the different evaporation temperatures of the components in the air. A cryogenic plant mainly consistsof a warm end (with an air compressor and a molecular sieve station) and a cold part(coldbox) with the rectification column where the actual air separation process takes place.Inlet filters remove dust and other mechanical impurities from the air before it enters theair compressor, where it is compressed to the required process pressure. It is then pre-cooled in the after-cooler or in a refrigeration drier. After passing through a moistureseparator, the air enters one of two molecular adsorbers, where impurities (such as water,

carbon dioxide, most hydrocarbons etc.) are removed. One of the two adsorbers isalways in operation while the other is being regenerated by residual gas from theseparation process. The process air is cooled down to almost liquefaction temperature inthe main heat exchanger in counter-flow with the cold separation products and then fedinto the bottom of the rectification column. There, the feed air is rectified. The pure nitro-gen fraction is withdrawn at the top of the column, heated up in counter-flow in the mainheat exchanger and then fed into the product line. Cold is supplied in the form of liquidnitrogen (LIN) from the back-up system or is generated with an expansion turbine.

The modularized design of the CRYOSS plants, combined with the back-up system,ensures best possible reliability and continuous gas supply. CRYOSS plants reflect manyyears of experience and are designed to the highest quality standards using state-of-the-arttechnology. All plant sizes are equipped as standard with PLC and a modem to enableremote monitoring and control. The nearest Linde operational center can thus keep theentire ECOVAR system under 24-hour surveillance.
ECOVAR systems based on CRYOSS plants are typically used for the following applications in the industries below:
Chemical and petrochemical industry Inerting/purging Blanketing Catalyst regeneration
Metallurgy/Glass industry Heat treatment Inerting Purging Refining
Subject to alteration. Printed on chlorine-free bleached paper.
