This page explains how Distillation Column is classified within Chemical Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A vertical vessel used to separate liquid mixtures into their individual components based on differences in volatility through the process of distillation.
Technical details and manufacturing context for Distillation Column
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Column Diameter | 0.5–6.0 m | Determines capacity and footprint. |
| Column Height | 10–60 m | Affects separation efficiency and installation space. |
| Number of Trays | 20–80 trays | More trays increase separation but increase pressure drop. |
| Operating Pressure | 0.1–1.6 MPa | Below 0.1 MPa vacuum operation may be required. |
| Design Temperature | -20–350 °C | Exceeding limit may require special materials.GB/T 150 |
| Material of Construction | SS304/SS316L | Corrosion resistance and cost trade-off.ASTM A240 |
| Wall Thickness | 6–30 mm | Thicker for high pressure or corrosive service.ASME B16.5 |
| Tray Spacing | 300–600 mm | Affects entrainment and pressure drop. |
| Separation Efficiency | 95–99.9 % | Higher efficiency reduces energy consumption. |
| Pressure Drop | 0.5–2.0 kPa/tray | Lower drop reduces energy cost. |
| Weight | 5–50 t | Important for foundation and lifting. |
| Corrosion Allowance | 1.5–3.0 mm | Higher for aggressive media.ASME B31.3 |

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory, the column diameter ranges from 0.5 to 6.0 meters, and the height from 10 to 60 meters. These are reference ranges; the actual dimensions depend on the specific process requirements and must be confirmed with the manufacturer.
The directory lists stainless steel and carbon steel as materials on file. For stainless steel, grades such as SS304 or SS316L are referenced under ASTM A240. The choice depends on corrosion resistance and cost, and should be verified for the specific application.
The directory references GB/T 150 for design temperature, ASTM A240 for material of construction, ASME B16.5 for wall thickness, and ASME B31.3 for corrosion allowance. These are verification references, not proof of certification.
The column operates on the principle of counter-current contact between rising vapor and descending liquid. Multiple equilibrium stages are created through trays or packing, allowing more volatile components to vaporize and rise, while less volatile components condense and flow downward. A reboiler generates vapor, and a condenser returns reflux to improve efficiency.
