Used Columns
Columns are often found in chemical processing, petroleum refineries and pharmaceutical facilities to distill high quantities of liquid. Choosing the right distillation column for your application requires more insight than simply knowing what you want to produce. You must consider several important factors, including surface area, flow rate and the volume of liquid being processed. The right design improves efficiency and ensures your operation delivers consistent results.
The experts at Louisiana Chemical Equipment Company can assist you in determining the right used packed columns for your organization’s specific distillation needs. Learn more about the used packed columns available from LCEC and key buying considerations below.
Common Types of Distillation Columns
Louisiana Chemical Equipment Company offers a wide selection of used columns, with options to suit a variety of applications. Our inventory often includes:
- Extraction columns: These use a third substance to adjust boiling points and allow separation of liquids that are otherwise difficult to split.
- Used packed columns: Packed columns use internal packing materials, such as metal, ceramic or plastic, to increase surface area inside the tower. Vapor rises as liquid flows downward, interacting with the packing to improve mass transfer and distillation efficiency.
- Trayed columns: With trays placed horizontally inside the tower, these columns collect liquid as vapor passes upward. The added surface area boosts separation and helps achieve higher purity levels.
Top Benefits of Used Packed Columns
Buying used equipment can give your business an edge. When you choose a used packed column from LCEC, you don’t have to wait months for a manufacturer to build and ship new machinery. Instead, the equipment is ready to be delivered and installed right away. That means less downtime and faster project completion.
Saving costs is another key advantage. Used packed columns provide reliable performance at a fraction of the cost of new equipment. Since many of our clients are already familiar with the equipment they need, the buying process is straightforward. You can browse our online inventory, request a quote and have a salesperson help confirm the details.
Some customers even purchase directly through our commerce site, which makes keeping projects moving easier.

Frequently Asked Questions
Industrial distillation columns come in several different types and sizes. Here are the answers to common column FAQs:
- What is another name for distillation columns? Generally, distillation columns are also known as distillation towers. Fractional distillation columns may be referred to as fractional towers, fractional columns or fractionating columns.
- What are the two types of distillation columns? Distillation columns are classified based on how they are used. The two main types are batch and continuous. With a batch column, the feed liquid enters in batches. One batch is distilled fully, then another feed batch enters the column. With a continuous column, the feed enters continuously, and the column constantly distills the feed stream into products for removal.
- What is the most common type of distillation column? Continuous distillation columns are more common than batch columns since they can handle larger volumes of feed liquid.
- What is the liquid called after distillation? The liquid that condenses after distillation is called the distillate. In some processes, part of the distillate is returned to the column to facilitate further separation. This portion is called reflux.
- How tall can a distillation column be? The maximum distillation tower height is about 200 feet tall. Most towers are between 20 and 50 feet tall, though some are as short as 12 feet. With plate distillation columns, the number of plates determines how high the column needs to be.
- How wide are distillation columns? On average, distillation columns are between 3 and 20 feet in diameter. However, some are as small as 6 inches across.
- What is the life span of a distillation column? The average distillation column lasts about 30 years.
