Applications and Characteristics

Applications

Columns / pressure vessel, made of Aluminium alloys, are used for the whole low- temperature service -269°C to +65° (4°K to 338°K). Rectifiers are basic components in plants for the treatment of cryogenic fluids and gases.

The main applications are:

Air separation plants

Gas separation plants

Gas liquefaction plants

Chemical and petrochemical plants

Typical Low-Temperature Process: Air Separation Plants

Liquid Oxygen / Nitrogen Production

The principle of plants based on separation of liquefied gases into several elements, e. g. liquid air to liquid oxygen and nitrogen and to inert gases like argon, krypton, xenon etc., supported by special internals.

Characteristics

Pressure vessels of aluminium alloys with special internals like:

Sieve trays

Bubble cap trays

Structured packings

Plate-fin heat exchangers

Condensers of tubular type

Tray column
