Abstract
Chemical engineering operations involving fluid transport, mixing, reaction, and separation are governed by nonlinear transport phenomena that often render first-principles optimization analytically intractable at industrial scale. Consequently, many processes rely on empirically tuned equipment and static control strategies. This paper proposes an alternative process architecture explicitly designed for artificial intelligence (AI)–driven optimization. The approach decomposes a chemical process into a sequence of identical, discretized unit operations—termed Universal Unit Processors (UUPs)—each acting on a finite quantum of fluid.
A mechanical realization of the UUP is introduced in the form of a Multi-Mode Piston (MMP), capable of controlled translation, rotation, and programmable fluid passage. By appropriate actuation, a single MMP unit can perform pumping, mixing, reaction facilitation, and selected separation tasks within a unified hardware structure. The standardized nature of the UUP enables consistent state–action representations that are well suited for data-driven control and reinforcement learning. A formal AI control framework is presented, defining state variables, control actions, reward functions, and learning across both individual units and interconnected networks.
