Explore our certified manufacturing output engineered to withstand rigorous hydraulic loads, thermal cycling, and aggressive chemical processing environments across Argentine industrial plants.
A rigorous review of vapor redistribution mechanics, pressure gradient containment, and leak-tight joint integration for critical distillation columns.
The chimney tray acts as the definitive boundary separating two packed or trayed sections in a column. Our chimneys are hydrodynamically sized with calculated net free areas (typically 15% to 25% of column cross-section) to eliminate localized vapor channeling, keep dry pressure drop under 4 mbar, and provide laminar feeding to upper packed beds.
Whether operating as a total draw-off tray feeding an external side stripper, or as a partial draw-off redistributor with calibrated overflow weirs, our internal seal pan geometry prevents gas entrainment into downcomers, maintaining continuous hydrostatic sub-cooling and preventing cavitation in bottom recycle pumps.
For installations where seal welding inside the vessel is restricted during fast-track turnarounds, our patented bolted design utilizes precision laser-cut flanges, high-density graphite or PTFE gaskets, and staggered clamping bars to achieve zero liquid leakage (<0.01 gpm/ft²) while allowing differential thermal movement across wide operational ranges.
Technical Insight for EPC Project Managers: In vacuum gas oil (VGO) fractionators and high-purity natural gas liquid (NGL) deethanizers, improper chimney hat clearances can cause re-entrainment of descending droplets into the up-flowing vapor core. Ambani Metals models every chimney tray using computational fluid dynamics (CFD) and rigorous hydraulic calculations to ensure the liquid frothing height remains at least 50 mm below the top of the chimney riser lip under maximum turndown and upset surges.
Comprehensive design envelope engineered according to ASME Section VIII Div. 1, API 560, and project-specific international EPC specifications.

Custom-engineered column internals tailored to the severe hydraulic, chemical, and climatic demands of Argentina's strategic industrial sectors.
Unconventional shale gas extraction in Loma Campana, Fortín de Piedra, and Añelo demands heavy-duty chimney collection trays for condensate stabilizers, amine sweetening towers, and TEG glycol dehydration contactors. Our trays provide robust resistance against sudden slugging, hydrocarbon condensation shifts, and extreme desert ambient temperature swings between day and night.
Within South America's major petrochemical enclave, ethylene, polyethylene, and aromatics fractionators require total drawoff chimney trays engineered with zero-leakage tolerances. Ambani Metals delivers high-nickel Hastelloy and 316L trays designed to collect reflux streams without thermal warping, guaranteeing uninterrupted feed to downstream reboilers.
The industrial river corridor along the Paraná River represents the world's most concentrated soybean crushing and biodiesel cluster. Our vacuum chimney trays and collector assemblies are manufactured in sanitary-grade SS316L, delivering high-efficiency fatty acid vapor separation, stripping steam recovery, and extreme thermal resilience under deep vacuum (<2 mbar absolute).
Upgrading downstream crude distillation and vacuum fractionators to produce ultra-low sulfur diesel (ULSD) demands manway-demountable chimney panels. Our trays are segmented to pass effortlessly through standard 450 mm and 600 mm vessel manways, drastically cutting turnaround downtime during maintenance overhauls at YPF, Raízen, and Pan American Energy facilities.
How energy infrastructure expansion, modernization initiatives, and the RIGI investment framework are accelerating process equipment acquisition.
With gas pipeline infrastructure (Gasoducto Presidente Néstor Kirchner / Perito Moreno) channeling surging volumes to the Atlantic coast, midstream operators are constructing large-scale NGL extraction, LPG fractionation, and LNG pre-treatment plants, creating sustained demand for ASME-grade chimney trays and distributors.
National blending targets for bioethanol (corn and sugar cane in Tucumán, Córdoba, and Salta) and biodiesel require older multi-column distillation systems to be debottlenecked. Replacing inefficient bubble cap arrays with low-pressure-drop chimney collection trays boosts production capacity by up to 35% without replacing vessel shells.
The implementation of the Régimen de Incentivo para Grandes Inversiones (RIGI) provides long-term tax, customs, and currency stability for multi-billion-dollar investments in Argentina. This regulatory tailwind is expediting project timelines for major petrochemical plants and export-oriented liquefaction trains requiring world-class process equipment.
Combining 25+ years of metallurgical mastery, in-house high-tonnage forming capabilities, and end-to-end export documentation.
All materials (SS304/L, SS316/L, Duplex 2205, Hastelloy, Monel) are sourced from Tier-1 mills with complete EN 10204 3.1 certification and heat-number tracking from raw sheet to final chimney weldment.
Equipped with 10,000-watt fiber laser cutting, multi-axis CNC press brakes, automatic seam welders, and deep-drawing presses, guaranteeing micron-accurate bolt alignment and flawless assembly fit.
Every chimney collector tray is pre-assembled on shop test rings matching your column's exact internal diameter. We perform dye penetrant tests, ultrasonic thickness audits, and hydrostatic seal-weld tests prior to dispatch.
Heavy-duty heat-treated ISPM-15 timber packaging, nitrogen-purged desiccants, vapor-corrosion-inhibiting (VCI) films, and clear match-marking tags ensure hassle-free customs clearance and rapid on-site assembly.
