Breaking down a plant into distinct, standardized systems or units, where processes like distillation, heat exchange, and chemical reactions are treated as individual building blocks, is the norm in the design and construction of chemical plants. Extending this norm to incorporate individually more complex units provides a foundational framework for modularization.

In traditional chemical plant, whereas equipment is segmented at an individual level – requiring hundreds to thousands of pieces to be transported and assembled on-site to construct a plant -, the modular approach makes for pre-fitting equipment into integrated systems at a workshop. This pre-assembly reduces the number of units to be transported and assembled at the construction site by an order of magnitude.

Now, the essence of partitioning of this kind lies in creating a framework where each module within a plant is a self-contained system capable of operating independently to serve a specific function or as part of an integrated process, and is designed with clear interfaces to connect seamlessly with other modules, enabling a systematic approach to plant design, construction, and operation. Examples would include a feedstock preparation module, an energy recovery module, and a modular utility system.

A significant advantage of such partitioning is standardization across various applications. Just as unit operations in traditional chemical engineering are universally recognized and replicated, partitioned modules could be developed with standardized specifications. As an example, a separation module using membrane filtration could be designed to handle specific flow rates and product compositions, making it applicable across multiple industries and chemical processes and allowing manufacturers to produce prefabricated units that are ready for rapid deployment.

Partitioning also addresses scalability, a critical need in markets with fluctuating demand or uncertain growth trajectories. By creating plants with modular components, it becomes possible to add or remove modules as needed. If demand for a particular chemical increases, additional reaction or separation modules can be integrated into the system without redesigning the entire plant.

To realize the full potential of partitioning, it is essential to establish clear standards and guidelines. Interfaces between modules must be defined to ensure seamless connectivity, while performance benchmarks must be set for each module to guarantee efficiency and compatibility. Regulatory compliance for modular systems must also be addressed, ensuring that partitioned modular plants meet safety, environmental, and operational requirements across different regions.
