Engineered Hybrid Performance
Trough-Pan Liquid-Gas Distributors combine the liquid-handling capacity of trough distributors with the gas-phase control of tray technology. Featuring integrated defoaming devices that capture micro-to-macro foams at inlet/outlet points, this compact design delivers 10:1 operational turndown while eliminating entrainment and fouling in foaming services.
Core Technology
| Innovation | Operational Impact |
|---|---|
| Hybrid Trough-Tray Design | Balanced gas-liquid distribution (±3% deviation) in foaming/contaminated systems |
| Multistage Defoaming | 99% foam destruction efficiency at velocities ≤0.3m/s |
| Corrosion Resistance | Available in U-PVC (≥pH 1-14), CS/SS316L, Hastelloy® |
| Low ∆P Gas Channels | Maintains <0.15psi pressure drop at 200% design capacity |
(Turndown elasticity: 10:1 vapor/liquid flow variance without redistribution degradation)
