1. Introduction
Carbon capture technologies rely heavily on stable, controlled temperatures to maintain catalyst performance, maximize CO₂ absorption, and minimize operational costs. Traditional heat exchanger technologies often create temperature irregularities that risk hot spots, catalyst degradation, and energy inefficiencies.
ATHCO Engineering addresses these challenges with pillow plate technology designed for precise thermal regulation and uniform heat distribution.

2. Pillow Plate Technology for Carbon Capture
ATHCO’s pillow plates are uniquely suited for carbon capture processes:
- Exceptional Heat Transfer Control
Customized plate expansion and weld patterns deliver exact heat transfer coefficients and pressure drops tailored to process requirements. - Uniform Heat Distribution
Engineered plate spacing and flow patterns eliminate hot/cold zones, protecting catalysts and maintaining optimal reaction conditions. - Optimized Flow Dynamics
Internal flow paths are precisely designed to maximize turbulence and thermal efficiency. - Robust and Modular Construction
Fully welded and self-supporting, pillow plates ensure reliable, scalable installation for both new builds and retrofits.
