Bubble Cap Trays for Controlled Vapor-Liquid Contact
Steel Fabrication India manufactures and exports Bubble Cap Trays for process applications where rising vapor must contact liquid held on a tray. The existing page describes a tray arrangement in which a riser is fitted over each tray opening and a cap covers the riser with clearance for vapor passage.
As vapor rises through the riser, the cap directs it downward through slots so it bubbles through the liquid on the tray. This configuration is presented on the source page as a solution where controlled vapor-liquid contacting and reduced leakage or weeping are important.
The published product data identifies stainless steel and copper materials, customized size, standard packaging and use as mass transfer media.
Customized SizeTray and component sizing supplied to project requirement.
SS & CopperMaterials listed on the existing product page.
Precise DesignDimensional accuracy is specifically identified in the source.
Low-Weeping OperationWide turndown range without weeping is listed as a product feature.
How It Works
Bubble Cap Tray Operating Principle
The source page explains the product as a staged vapor-liquid contacting device built around a riser, cap and cap slots.
Vapor Rises Through the Riser
Vapor entering from below the tray passes upward through the riser installed over the tray-floor opening.
Cap Redirects the Vapor
The bubble cap covers the riser and directs the rising vapor downward toward the cap slots.
Vapor Bubbles Through Liquid
Vapor is discharged through slots in the cap and bubbles through the liquid retained on the tray.
Phase Contact Takes Place
The tray arrangement is used to promote interaction between the vapor and liquid phases for mass-transfer duty.
Wide Turndown Range
The current product information lists a wide range of turndown ratios without weeping as a key feature.
Controlled Tray Performance
The existing content emphasizes efficient vapor handling, dimensional accuracy and precise design.
