​​ Engineered Vapor-Liquid Contact​​ Vertical Sieve Trays (VSTs) feature chimney-like risers (Ø100-200mm) with perforated sidewalls and calibrated bottom clearances. This design creates renewed gas-liquid interfaces while eliminating droplet entrainment – achieving ​​40% higher capacity​​ and ​​20% greater efficiency​​ than conventional sieve trays in FCC main fractionators, NGL columns, and amine regenerators. ​​Core Anti-Blo

Engineered Simplicity​​ Metal Sieve Trays deliver reliable vapor-liquid contact through precision-perforated plates requiring zero moving parts. Designed for fouling/corrosive services, they offer 30-50% cost savings over valve trays while enabling extended liquid residence times (>60s) – ideal for refinery scrubbers, chemical reactors, and processes where phase contact duration outweighs turndown flexibility needs. ​​Core

​​Engineered for Challenging Processes​​ Metal Bubble Cap Trays utilize inverted caps over vapor risers to force gas through slot-orifices, creating uniform bubbling through liquid layers. This design maintains stable vapor-liquid contact at ultra-low gas rates (<0.5 m/s) while accommodating liquid depths up to 150mm – ideal for reactive absorption, amine regeneration, and caustic concentration systems where process stabili

Dynamic Flow Control​​ F1 Metal Conventional Valve Trays feature circular valves with twist-locked legs that automatically modulate openings based on gas velocity. This self-adjusting design maintains optimal vapor-liquid contact across 4:1 turndown ratios while preventing valve detachment – delivering reliable efficiency in FCC main fractionators, NGL columns, and gas sweetening units. ​​Core Mechanism​​ ​​Component​​ ​​Funct

Engineered for Reliability​​ Metal Fixed Valve Trays feature permanently open valve units that deliver sieve-tray simplicity with enhanced vapor-liquid contact. By eliminating moving parts, they prevent wear/sticking while achieving 20-30% higher capacity and 6:1 turndown ratios versus sieve trays – ideal for fouling services like FCC main fractionators and PVC slurry strippers. ​​Performance Advantages vs. Sieve Trays​​ ​​Par

​​Trapezoidal Valve Innovation​​ Guided Metal Conventional Valve Trays feature patented trapezoidal valves that redirect gas flow at acute angles to liquid movement, creating synergistic forward thrust. This Tianjin University-developed design slashes tray pressure drop by 15-20%, extends turndown flexibility (33% lower gas load limit + 20% upper limit), and eliminates stagnant zones in refinery fractionators and petrochemical
