Process Systems Engineering Lab
Machine-translated · View original
The lab designs production systems, from microchemical systems to the global environment.

AboutAbout the lab
Designing production systems rationally.
The Process Systems Engineering Lab conducts research on the theme of "synthesis and optimization of systems."
There is growing demand for production systems that can make high-value products while saving resources and energy.
Process systems engineering is the discipline that studies methodologies for designing and operating such systems rationally.
Through advancing the field, training people, and returning research results to society, the lab aims to contribute to the development of Japanese industry.
Key terms
- Microchemical process
- A way of carrying out chemical synthesis inside thin, micrometer-scale channels, where mixing and heat exchange happen quickly
- Distillation
- An operation that heats a liquid and separates its components based on differences in boiling point. It uses a large amount of energy in chemical plants
- Distributed chemical process
- A system that produces chemicals in small amounts in each region where resources are available, rather than concentrating production in one large plant

ResearchResearch themes
In a society facing difficult challenges such as environmental problems, there is demand for producing high-value products while also conserving resources and energy. The lab studies methodologies for rationally designing and operating production systems, from microchemical systems to the global environment.
*Illustrative imageBuilding microchemical plants
Using fluid simulation and optimization, the lab designs the shape and dimensions of small devices and fabricates them with 3D printers. The aim is to establish fundamental technologies for designing, operating, and controlling plants that make the most of the strengths of microchemical processes: fast mixing and heat exchange.
*Illustrative imageRethinking chemical equipment from the ground up
The lab organizes and combines basic chemical operations and phenomena to develop new chemical equipment and processes. It is devising energy-saving distillation equipment that works on a different principle from conventional equipment, and investigating its performance through experiments and simulation.
*Illustrative imageSystems that make use of local resources
The lab studies distributed chemical processes that make use of resources scattered across regions, such as biomass. It is developing a system that rapidly finds the optimal decision on which reaction to carry out, when, and where, based on cost and environmental impact.
