Glass-Lined Columns
We are able to design and manufacture glass-lined columns up to DN 2400. Our expertise enables us to design columns with flanges of unequalled flatness.
Best in class glass-lined columns
Our vast experience with this product allows us to produce columns with very flat flanges to simplify the installation and ensure good sealing.
Additionally, we can provide column internals in various materials to fit your process requirements.
Columns with high corrosion resistance
De Dietrich® DD3009 glass-lining is extremely resistant against acids, providing a cost-effective and temperature-resistant alternative to special metallic materials and non-vacuum-resistant PTFE-lining.

Thermal Separation Processes for Efficient Chemical Treatment
Thermal separation processes play a crucial role in the treatment and purification of chemicals. These processes commonly involve two liquid phases or a liquid and a gas. The most widely used techniques include extraction, absorption, desorption (or stripping), distillation, and rectification.
Effective separation relies on mass transfer between two phases, such as between a liquid and a gas. To maintain a compact equipment design, it is essential to maximize the mass transfer surface within the smallest possible volume. This is achieved using columns equipped with specialized internals in thermal process engineering.
The core of these columns consists of structured internals that enhance mass transfer efficiency. These include:
- Packings: Either random or structured, providing the necessary surface for mass transfer.
- Trays: Such as bubble-cap or sieve trays, ensuring proper phase interaction.
To optimize performance, additional internal components ensure uniform liquid distribution across all surfaces. These include:
- Liquid distributors: Evenly spreading the fluid across the column cross-section.
- Wall wipers: Redirecting liquid from the column walls back into the packing.
- Demisters: Preventing droplet carryover at the top of the column.
- Collectors: Capturing reflux liquid for removal or redistribution.
- Vortex breakers and lower-end collectors: Ensuring reliable liquid drainage.
Custom Engineering for Your Application
For optimal process performance, column designs and materials vary depending on the application and column diameter. Our expertise allows us to tailor the design and select the most suitable internal components for your specific requirements.
From basic engineering to start-up, we offer a complete, integrated solution to ensure efficiency and reliability in your thermal separation processes.
