  We present a novel dynamic model of a flash clay calciner. The model consists
of thermophysical properties, reaction kinetics and stoichiometry, transport,
mass and energy balances, and algebraic constraints. This gives rise to a
system of partial differential-algebraic equations (PDAE). Spatial
discretization is performed to convert the PDAEs into a system of
differential-algebraic equations (DAE). The model can be used, for example, to
perform dynamic simulations with changing inputs, and process design and
optimization. Moreover, it can be used to develop model-based control, which is
relevant for flexible operation of a clay calcination plant for green cement
production.
