Find Your Tower Internals & Components

Every operation is different. That's why Sutong provides a wide range of tower internals and parts, made to solve your specific separation problems. Look through our main product groups here.

Random Packings

The economical and versatile option for general separations, offering high surface area and fouling resistance in absorption and stripping processes.

Structured Packings

The high-efficiency choice for precise mass transfer, with low pressure drop and high capacity in distillation and gas cleaning applications.

Liquid Distributor

The critical component that governs packed tower efficiency by ensuring uniform liquid distribution across the bed.

Mist Eliminator

The final line of defense, capturing liquid entrainment to protect downstream equipment and prevent costly product loss.

Column Trays

The choice for distinct separation stages, offering robust and predictable performance in high-liquid or fouling-prone systems.

Hump Support

Engineered to balance the demands of robust mechanical support with the need for unrestricted vapor flow from below.

Internals

The essential hardware—collectors, feed pipes, etc.—that enables the column to operate as a single, high-performance system.

Boosting Efficiency & Saving Costs
Increasing Capacity & Throughput
Improving Reliability & Handling Fouling
Meeting Environmental Regulations

Refinery Cuts Steam Use with Packed Tower Upgrade

An existing packed tower used too much energy. Sutong replaced the internals with high-efficiency packing and better distributors, slashing steam use and lowering operating costs.

Gas Plant Smashes Bottleneck with Tower Revamp

A natural gas plant's production was capped by an underperforming absorption tower, causing costly operational issues. Sutong's tray-to-packing conversion, featuring high-performance internals, boosted throughput by 33% and unlocked millions in annual revenue.

Refinery Extends Run Time from 1 Year to 4+ Years

Frequent, costly shutdowns due to severe fouling crippled a refinery's key fractionator. By installing robust, anti-fouling SG-Grid™ packing, Sutong extended the unit's run time from under 12 months to over four years, dramatically improving reliability and saving millions in lost production.

Chemical Plant Exceeds EPA Standards with Scrubber System

Faced with tough new EPA emission limits, a chemical plant needed a guaranteed solution to avoid fines or shutdowns. Sutong delivered a custom-engineered packed tower scrubber that slashed toxic gas emissions to just 10% of the new legal limit, ensuring "beyond compliance" performance and operational peace of mind.
