US 2026/0216641 A1 · WASTE-HEAT RECOVERY SYSTEM FOR CARBON CAPTURE

Abstract

The present disclosure provides integrated systems and methods that combine waste heat recovery (WHR) with carbon capture operations. By simultaneously managing process stream temperatures and generating power from recovered thermal energy, the disclosed technology offers comprehensive solutions for both thermal management and power consumption challenges. The system maintains optimal lithium-zirconate (LZO) operating temperatures while converting waste heat to electrical power through various thermodynamic cycles, including Brayton, Rankine, and thermoelectric generation. Applications span both stationary facilities and mobile implementations, enabling carbon capture while reducing overall system power requirements and improving operational efficiency.
