When your process demands efficient separation, purification, or distillation, industrial columns offer scalable, high-performance solutions across a wide range of industries. With over 47 years of process equipment expertise, IPP provides immediate access to high-quality used columns sourced from 20 complete plant sites and included in our inventory of over 15,000 ready-to-ship pieces of equipment. Choosing used columns from IPP helps companies reduce capital investment, shorten project lead times, and maintain efficient separation performance.

Industrial columns are vertical vessels designed to facilitate mass transfer between phases — such as gas-liquid or liquid-liquid — making them essential for distillation, absorption, stripping, and extraction processes. Their design and internal configuration are critical to achieving precise separation efficiency.

Column FAQ
Have questions about Columns or our services? Learn more about our products and why customers choose IPP.
Chemical, oil and gas, pharmaceutical, food and beverage, and environmental industries all depend on columns for critical separation and purification processes.
Packed columns offer lower pressure drop and are ideal for small to medium flow rates, while tray columns are more robust for large flows and easier to clean and inspect.
Routine maintenance includes inspecting packing or trays, checking for corrosion or fouling, verifying pressure and temperature sensors, and cleaning internals as needed.
Buying used from IPP can save up to 70% over new equipment, provide immediate project solutions, support sustainability, and tap into over 47 years of trusted industry expertise.
