Introduction
The Absorption and Desorption Educational Unit Operations Pilot Plant is an integrated, bench-scale laboratory system designed to facilitate practical instruction in gas-liquid mass transfer processes. Featuring a dual-column configuration—comprising a packed absorption column and a packed desorption column—the unit allows undergraduate students to study gas absorption and stripping dynamics. By measuring volumetric mass transfer coefficients under varying spray densities, students gain firsthand experience with the principles of liquid film control, fluid dynamics, and column packing performance, bridging the gap between theoretical classroom concepts and industrial process engineering.
Customization and Adaptability
Recognizing that different academic institutions have unique curriculum structures and space constraints, this pilot plant is designed with flexibility in mind. Both the hardware components and the software interfaces can be fully customized to align with your department’s specific laboratory syllabus, space limitations, and research-integrated teaching requirements.
