Project Associate 1 @Indian Institute of Technology, Madras
Chennai, IN
Worked on CO₂ capture using 3D printed zeolite monoliths prepared via Direct Ink Writing (DIW) using Zeolite 13X powder with binders (bentonite) and plasticizers (methyl cellulose)• Performed calcination of printed monoliths and evaluated their structural integrity and adsorption performance in fixed-bed column setups• Conducted adsorption studies using CO₂/N₂ gas mixtures (80:20) to analyze breakthrough behavior and assess monolith design performance• Transitioned from lab-scale monolith systems to pilot-scale CO₂ capture using Zeolite 13X beads• Operated VPSA (Vacuum Pressure Swing Adsorption) systems involving cyclic adsorption-desorption processes• Performed both batch and dual-column experiments to evaluate adsorption capacity, breakthrough curves, and CO₂ production rates• Analyzed system performance under different operating conditions to understand cyclic stability and scale-up behavior

ABOUT HARISH RAGAVENDRAN
I am a Chemical Engineer currently working as a Project Associate at IIT Madras, focusing on pilot-scale CO₂ capture using adsorption-based separation systems.My work involves operating and analyzing VPSA cycles using Zeolite 13X (APG grade), where I work closely with dual-column setups under continuous and batch modes. A major part of my role is understanding real system behavior from breakthrough trends and adsorption capacity to cyclic stability over repeated runs.Instead of working with ideal models, I am involved in how systems actually perform at scale, including flow variations, bed configurations, and long-cycle performance.Prior to this, I worked on 3D printed monolith structures for adsorption applications, and also gained pilot-scale exposure in e-waste recovery through electrowinning processes. My mini project work also includes wastewater treatment using glycol-based systems.These experiences have shaped my interest towards process scale-up, system design, and developing practical solutions in carbon capture and separation technologies.I am now looking to pursue a Master’s program abroad to deepen my understanding in adsorption systems, process engineering, and sustainable technologies.Open to collaborations, research discussions, and opportunities in CO₂ capture, adsorption systems, and process engineering.
