The Challenge
A biochar production facility producing approximately 0.775 tons per hour (TPH) sought to significantly increase throughput to meet growing market demand. However, the existing system faced stability issues when pushed beyond nominal rates, suggesting that critical equipment - specifically fans and heat exchangers - were operating near their mechanical or thermal limits.
Specific operational concerns included excessive pressure drops across the heat exchangers, capacity limitations in the vapor blower, and mechanical risks regarding reactor drum thermal expansion. The client required a detailed engineering analysis to identify the specific bottlenecks and a verified roadmap to safely scale production to a conservative 1.75 TPH (with expectations upwards of 2.5 TPH) without compromising safety, equipment reliability or safety.
Modeling the Path to Higher Throughput
CPE utilized field measurements and historical operational data to build rigorous pyrolysis and heat & mass balance models, simulating future production scenarios to identify equipment constraints (thermal, hydraulic, and bulk handling).
