Cryogenic Distillation Columns

Linde' supreme experience in air separation technology

We are at the front seat of cryogenic column design and manufacturing. We manufacture distillation columns/ cold boxes in India for ASU application.

Cryogenic columns are pressure vessels made of Aluminum & SS Stainless Steel alloy. They are used as rectifiers, purifiers, and stabilisers at low temperatures of between -269°C and +65°C (4°K to 338°K). The columns are key components in the treatment of cryogenic fluids and gases and are typically used in air separation plants, gas separation and liquefaction plants as well as in chemical and petrochemical plants. We design cryogenic columns in line with our own hydraulic layout or to customer specifications.

A single column can measure up to 7 m in diameter, be up to 45 m long, and weigh up to 170 tons. The walls can be up to 70 mm thick. Components that exceed these dimensions are welded at Linde workshops near harbours or directly on site.

We build our columns in line with international standards and deploy special welding technology and sophisticated equipment to achieve optimal quality.

Our experienced specialists collaborate with international forwarding agents and shipping lines to ensure that components are transported with the utmost care by road or by sea.
