Bubble Cap Risers with Fittings
Kalyros Engineering LLP proudly manufactures high-quality bubble cap risers with fittings, essential components for bubble cap trays used in distillation and absorption columns. These risers, paired with bubble caps, enhance vapor-liquid contact, ensuring efficient separation processes across various industries. Our precision-engineered risers are designed to meet the demanding needs of chemical, petrochemical, pharmaceutical, and refining sectors.
Manufacturing Process
Material Selection
High-grade metals such as stainless steel, carbon steel, or corrosion-resistant alloys are selected based on the application requirements.
Cutting and Shaping
Raw materials are cut into precise cylindrical shapes using CNC milling machines to form the riser structure.
Perforation and Fitting
Risers are perforated or fitted with slots as per design specifications. Fittings including bolts and supports are integrated using precision welding or press-fitting techniques.
Assembly
Internal supports or dividers are added for structural integrity and proper vapor flow. Risers are assembled with threaded bolts for secure attachment to the tray floor.
Finishing
Components undergo surface treatment such as polishing or coating to enhance corrosion resistance and durability.
Quality Control
Each riser is rigorously tested for dimensional accuracy, strength, and performance under simulated operating conditions before dispatch.
Design and Functionality
Bubble cap risers are vertical cylinders fitted over holes in the tray deck of a distillation column. They are covered by bubble caps, which direct vapor upward through the riser and then downward through slots, allowing it to bubble through the liquid on the tray. This design ensures maximum vapor-liquid contact, preventing weeping (liquid leakage) and maintaining efficiency even at low liquid or vapor rates. The risers are secured to the tray using methods like seal welding, through bolting, or swaging, ensuring a leak-proof seal.
