Internals Selection Starts with the Separation Requirements
Selecting trays, packing, distributors or demisters should not start from a product catalogue. The separation duty, operating data, vapor and liquid loads, hydraulic limits and operating constraints should be reviewed first. SEPPRIME connects these conditions to internals selection, design and technically controlled supply.
Separation Requirements
What separation target and performance criteria must the column meet?
Data & Simulation
Are the design basis and vapor/liquid loads reliable?
Column Hydraulics
Where are the flooding, pressure-drop or turndown limits?
Internals Design
Which trays, packing, or other column internals fit the duty?
Controlled Supply
Translate the engineering basis into drawings, fabrication requirements and delivery.
Column Internals Selected Around Process and Hydraulic Requirements
SEPPRIME supplies trays, packing, distributors, mist eliminators and other column internals for distillation, absorption, stripping and related mass transfer services. Selection is based on separation requirements, vapor and liquid loads, pressure-drop limits, operating flexibility, fouling tendency and installation constraints.
Trays & Tray Internals
Valve, sieve and other tray systems for capacity, efficiency, turndown and revamp requirements.
Structured Packing
Low-pressure-drop mass transfer internals for high-efficiency, vacuum and separation-sensitive services.
Random Packing
Practical packing options for absorption, stripping, scrubbing and general mass transfer duties.
Column Internals
Distributors, supports, hold-downs, collectors and related internals for reliable packed-column performance.
Mist Eliminators
Wire mesh and vane-type solutions for droplet removal, carryover control and downstream protection.

Column Problems We Help Diagnose
Flooding, weeping, entrainment, high pressure drop, and poor separation are symptoms—not diagnoses. SEPPRIME reviews process conditions, operating data, hydraulic limits, and internals configuration before recommending corrective action.
Column Flooding
Identify whether excessive vapor/liquid load, foaming, internals limitations, or operating changes are restricting column capacity.
High Pressure Drop
Check whether the pressure-drop increase is caused by hydraulic overload, fouling, internals condition, or changed operating conditions.
Poor Separation Efficiency
Separate process-side causes from tray, packing, distribution, or hydraulic limitations before considering internals replacement.
Tray Weeping
Evaluate vapor load, tray open area, pressure drop, liquid head, and operating turndown when liquid leakage occurs.
Downcomer Flooding
Review inlet backup, froth behavior, residence time, outlet restriction, and tray geometry when liquid accumulates in the downcomer system.
Packing Maldistribution
Assess distributor performance, wetting quality, liquid load, packing condition, and installation when packed-bed performance deteriorates.

Selected Column Engineering Cases
See how process data, hydraulic evaluation, internals design, and option comparison are used to diagnose column problems and develop practical solutions.
Troubleshooting Tray Flooding in a Refinery Fractionation Column
Operating data and tray hydraulics were reviewed to determine whether the capacity limitation was related to vapor load, downcomer behavior, tray configuration, or operating conditions.
Hydraulic bottleneck identified and revamp options compared.
Reducing Pressure Drop in a Packed Distillation Column
Existing vapor and liquid loads, packing configuration, pressure drop, and operating margin were reviewed before comparing packing and internals upgrade options.
Lower-pressure-drop configuration evaluated and upgrade options compared.
Improving Liquid Distribution in a Packed Absorption Column
Distributor loading, liquid distribution quality, packing configuration, and operating conditions were evaluated to identify the likely cause of uneven bed performance.
Distributor and packing-side improvement path defined.
