Product DescriptionProduct DescriptionSS316 Liquid Distributors 1. Function & ImportancePrimary Role: Ensures uniform liquid distribution over packing surfaces to maximize mass transfer efficiency in distillation, absorption, and extraction processes.Key Benefits:Reduces channel flow and wall flow, minimizing tower height/diameter and construction costs.Enhances contact between gas/liquid phases, critical for separation efficiency.2.Design SpecificationsDistribution Density: ≥100 points/m2 to ensure uniformity.Flow Non-Uniformity: <5% for optimal performance.Gas Flow Area: ≥25% to minimize pressure drop.Material Selection:Stainless Steel (304/316): General corrosion resistance.Ceramics: Withstand ≤800°C (e.g., high-temperature distillation).PTFE: For highly corrosive media (e.g., HCl absorption).Integration with Packing SystemsRedistribution Requirements:Models with integrated liquid collection require interlayer redistribution devices to maintain uniformity in tall towers.Critical for packed beds exceeding 3-5 meters to avoid maldistribution.Industry ApplicationsPetrochemical: Crude oil distillation, amine scrubbing.Pharma: Solvent recovery in vacuum columns.Environmental: VOC absorption in scrubbers.SpecificationStructural Types & ApplicationsTypeProsConsTypical Use CasesTubularLow resistanceProne to cloggingMedium-low liquid loadsTroughAnti-fouling, handles high loadsLarger footprintHigh loads, viscous liquids (e.g., petrochemicals)DiscIntegrated gas-liquid separationHigher costSpace-limited conditions (elasticity 10:1)Structured Technical Explanation of Liquid Distributors in Packed Towers1. Core Functions of Liquid DistributorsUniform Distribution: Evenly disperses liquid at the top or intermediate heights of packing to:Maximize effective interfacial area for mass/heat transfer.Minimize channel flow, bias flow, and wall flow (non-uniform flow patterns).Redistribution: Corrects liquid maldistribution in tall towers to prevent amplification/end effects (where flow irregularities worsen down the column). 2. Impact of Poor Distribution (Experimental Findings)Flow Phenomena:Channel Flow: Liquid concentrates in narrow paths, reducing contact efficiency.Bias Flow: Uneven distribution across the packing cross-section.Wall Flow: Liquid adheres to tower walls, bypassing the packing.Consequences:Higher HETP (Height Equivalent to a Theoretical Plate), increasing tower height/diameter.Reduced separation efficiency, raising operational costs (e.g., energy, reflux ratios).3. Design Principles to Mitigate EffectsInitial Distributor Design:Distribution Density: ≥100 points/m2 to ensure uniformity.Flow Non-Uniformity: <5% (critical for high-efficiency packing like structured grids).Redistributor Placement:Required every 3–5 bed diameters (or 5–10 meters) to reset maldistribution.Integrated gas-liquid separation in disc/trough types (e.g., Sulzer's Mellapak? redistributors). 4. Economic & Operational BenefitsCost Reduction:Lower tower height/diameter due to improved efficiency (reduces material/construction costs).Energy savings from optimized flow (e.g., reduced reflux in distillation).Material Selection:Stainless Steel (316L): For corrosive services (e.g., amine scrubbers).Ceramics/PTFE: Extreme temperatures/corrosion (e.g., HCl absorption). 5. Industry ApplicationsDistillation: Crude oil fractionation, solvent recovery.Absorption: CO2 capture, VOC removal.Pharmaceuticals: High-purity separations in vacuum columns.Company ProfilePingxiang Rongjian Environmental Protection Chemical Packing Co., Ltd.Innovative Solutions for Environmental & Industrial ApplicationsHeadquarters: Xiangdong District Industrial Park, Pingxiang City, Jiangxi Province, China Core Capabilities Advanced Manufacturing: Custom-designed towers and systems in ceramic, metal, and plastic materials.Comprehensive Product Portfolio: 200+ specifications including:?
