MULTISCALE POROUS HIGH-TEMPERATURE HEAT EXCHANGER USING CERAMIC CO-EXTRUSION

Massachusetts Institute of Technology (MIT)
Program: 
ARPA-E Award: 
$1,714,940
Location: 
Cambridge, MA
Project Term: 
08/22/2019 to 08/21/2022
Project Status: 
ACTIVE
Technical Categories: 
Critical Need: 

Heat exchangers are critical to efficient thermal energy exchange in a variety of applications--including electricity generation, transportation, petrochemical processing, and waste heat recovery. Heat exchangers designed to handle ultra high pressures and high temperatures simultaneously would help to facilitate more efficient and cost effective thermochemical processes. However, the successful design of such devices is expected to require heat transfer surface and fin features that are too fine for current high temperature material manufacturing processes. Durable, reliable, and cost-effective higher temperature and pressure heat exchangers that exceed current operating conditions could reduce fuel consumption, system footprint, and capital cost while boosting the performance of a variety of power generation and industrial processes.

Project Innovation + Advantages: 

MIT will develop a high performance, compact, and durable ceramic heat exchanger. The multiscale porous high temperature heat exchanger will be capable of operation at temperatures over 1200°C (2192°F) and pressures above 80 bar (1160 psi). Porosity at the centimeter-scale will serve as channels for the flow of working fluids. A micrometer-scale porous core will be embedded into these channels. A ceramic co-extrusion process will create the channels and core using silicon carbide (SiC). This core design will significantly improve heat transfer and structural strength and minimize pressure drop, enabling very high power density.

Potential Impact: 

HITEMMP projects will enable a revolutionary new class of heat exchangers and innovative approaches to advanced manufacturing with applications for a wide range of commercial and industrial energy producers and consumers.

Security: 

High performance, efficient heat exchangers would increase industrial productivity, supporting domestic industries. The developed manufacturing techniques for high temperature materials could strengthen U.S. leadership in advanced manufacturing.

Environment: 

More efficient electricity generation and industrial processes could significantly reduce emissions by enabling more efficient operations.

Economy: 

HITEMMP technologies could enable more cost-effective, efficient, and compact modular power generation systems for multiple applications.
