CHAPTER 6:The Energy Balance for Chemical Reactors

Reactor 2:The reactor pressure is held constant (reactor volume therefore changes). Both reactors are charged with pure A at 1.0 atm and k has the usual Arrhenius activation energy dependence on temperature, k (T ) = k 0 exp( E = T ) The heat of reaction, H R, and heat capacity of the mixture, C^P, may be assumed

These reactors typically have vents which are opened and closed during emptying, filling, mixing, heating or cooling and other steps of the production process. The gases coming from these vents must be controlled under most government regulations.

Solar Thermochemical Energy Storage | AIChE

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.
