5 Common Mistakes When Ordering Tower Internals and How to Avoid Them

5 Common Mistakes When Ordering Tower Internals and How to Avoid Them

Introduction

Tower internals are critical components inside packed columns, absorption towers and gas-liquid separation equipment.

However, many project delays and performance issues happen because important technical details are overlooked during the purchasing process.

Choosing the correct tower internals supplier requires more than comparing prices. Engineers need to confirm design requirements, materials, dimensions and installation conditions before placing an order.

DAIER Separation provides customized tower internals including liquid distributors, packing supports, hold down grids and mist eliminators for industrial separation applications.

Mistake 1: Providing Incomplete Technical Information

One of the most common problems is requesting a quotation without enough project information.

Missing information may include:

• Tower diameter

• Internal dimensions

• Operating conditions

• Material requirements

• Installation limitations

Without complete data, suppliers cannot accurately design suitable internals.

How to Avoid This Problem

Prepare basic technical information:

• Tower drawing

• Equipment dimensions

• Process conditions

• Existing internal design

• Required materials

Mistake 2: Selecting Internals Only Based on Price

The lowest quotation is not always the best solution.

Tower internals directly affect:

• Separation efficiency

• Equipment reliability

• Maintenance frequency

A cheaper component may create additional costs if:

• Material is unsuitable

• Design is incorrect

• Performance is insufficient

How to Avoid This Problem

Evaluate:

• Supplier experience

• Material quality

• Engineering capability

• Manufacturing process

• Previous project experience

Mistake 3: Ignoring Installation Conditions

Tower internals must fit the actual equipment.

Important installation factors include:

• Manway size

• Internal access

• Segmentation requirements

• Lifting method

Large components may need to be divided into smaller sections for installation.

How to Avoid This Problem

Confirm:

• Maximum single-piece dimension

• Installation method

• Assembly requirements

• Site limitations

Mistake 4: Choosing Materials Without Considering Operating Conditions

Tower internals may operate in challenging environments.

Material selection should consider:

• Chemical corrosion

• Temperature

• Pressure

• Mechanical requirements

Common materials:

Stainless Steel

Used for:

• High temperature applications

• Chemical processing

Plastic

Used for:

• Corrosive environments

• Scrubber systems

Special Alloys

Used for:

• Highly corrosive applications

Mistake 5: Replacing Components Without Checking the Complete System

Tower internals work together.

For example:

• Poor liquid distribution may not be solved by replacing packing only.

• Damaged supports may affect packing performance.

• Poor mist removal may require demister replacement.

How to Avoid This Problem

Evaluate the complete tower system:

• Packing

• Distributor

• Support system

• Mist eliminator

• Operating conditions

Tower Internals Ordering Checklist

Before placing an order, confirm:

✅ Tower diameter
✅ Installation method
✅ Manway size
✅ Internal segmentation
✅ Material requirement
✅ Operating temperature
✅ Operating pressure
✅ Gas and liquid conditions
✅ Drawing availability
✅ Packing compatibility

Conclusion

Ordering tower internals requires careful evaluation of engineering requirements, materials and installation conditions.

A reliable supplier should not only manufacture components but also help verify the design details required for successful operation.

DAIER Separation provides customized tower internals solutions for packed columns, absorption towers and gas-liquid separation systems.
