II this is the reaction rate with respect to the reactants, the one with respect to the products being -r = +k' · (cD) · (cE)
Because the purpose of the chemical process is energy storage, a critical component of the subsystem is the storage tanks. Thermochemical storage mechanisms have a higher energy density than thermal methods, which could help lower capital costs by reducing storage tank volumes ().When energy is required from storage, the TCES subsystem delivers heat to the power block.

Jun 23, 2020 · 4.1 Introduction. A Continuous Stirred-Tank Reactor (CSTR) is a chemical reaction vessel in which an impeller continuously stirs the contents ensuring proper mixing of the reagents to achieve a specific output (Figure (PageIndex{1})). Useful in most all chemical processes, it is a cornerstone to the Chemical Engineering toolkit. Proper knowledge of how to manipulate the .
The selection of a chemical reactor can be formulated as guidelines in term of relative performance of the two basic types, CSTR and PFR, as presented in Table 2.4.In many cases, the PFR offers better productivity and yield, particularly at high conversion. However, the CSTR is superior from the viewpoint of heat and mass transfer.
This was studied 25–30 years ago in the German ADAM/EVA scheme in which the heat produced in a high temperature, gas cooled nuclear reactor was converted into chemical energy by the steam reforming reaction (EVA). The heat was transferred in a closed loop of helium at 950 °C and 40 bar which was efficient to drive the tubular reformer.
