Product Description
Hydrodynamics of Packed Bed the set up is capable to study the loading and flooding characteristics. It is a packed column packed with Raschig Rings where the Air is counter currently fed to column. Liquid holdup in the column increases the weight of column and also reduces the effective porosity of packing. This reduction in porosity decreases the gas velocity, increases the pressure drop and changes the value of mass transfer co-efficient. The water is fed from the top of the column and loading & flooding characteristic are observed on various flow rates of Air and Water.

Enhanced Process Visibility and ControlThe apparatus includes transparent column sections constructed from borosilicate glass or acrylic and a front-loading acrylic door, offering exceptional process visibility. Real-time observation of flow patterns and packed bed behavior during experiments is facilitated, enhancing both teaching and learning experiences. Ball valves and rotameters provide precise flow control and adjustment, supporting a variety of hydrodynamic experiments.
User-Friendly Operation and Data RecordingManual filling and draining, along with accessible sample ports at both the column's top and bottom, guarantee easy operation and comprehensive data collection. The U-tube manometer delivers accurate, continuous pressure readings to monitor bed hydrodynamics. An external, well-insulated system maintains uniform heat, supporting experiments at temperatures up to 70C.
FAQ's of Hydrodynamics of Packed Bed:
Q: How does the packed bed hydrodynamics apparatus work?
A: The apparatus circulates liquid or air through a packed column filled with Raschig rings or glass beads. Flow characteristics and pressure drop are observed and measured using a U-tube manometer and sample ports, allowing students to study the fundamentals of packed bed hydrodynamics.
Q: What materials are used for the column and packing in this setup?
A: The column is constructed from borosilicate glass or acrylic for both chemical resistance and visibility. Packing material options include Raschig rings or glass beads, which provide consistent and analysable flow patterns.
Q: When is compressed air required during operation?
A: Compressed air is necessary when experiments require air flow through the column, enabling studies of gas-liquid interactions or airflow behavior in packed beds.
Q: Where can samples be collected during experiments?
A: Samples can be collected from ports located at both the top and bottom of the column, providing flexibility for monitoring and analysis at different stages of the experiment.
Q: How is the flow rate and pressure monitored?
A: The apparatus is equipped with a rotameter for real-time flow rate adjustment and a U-tube manometer with scale for precise measurement of pressure drop across the packed bed.
Q: What is the main benefit of using this apparatus in chemical engineering laboratories?
A: It enables hands-on experimentation and clear visual observation of packed bed hydrodynamics, helping students grasp theoretical concepts and gather experimental data for analysis.
Q: What safety and durability features are included?
A: The unit features double-wall insulation, a robust mild steel frame with powder coating, and corrosion-resistant stainless steel piping. These ensure safe operation, structural integrity, and extended service life in laboratory environments.
