Chemical Reaction System - an overview | ScienceDirect Topics

We consider the general case of a multiple chemical reaction system.The species comprising the elementary reactions that describe the detailed chemistry of the process are divided into the surface active sites S, the surface intermediates I 1, I 2, ., I q, and the gaseous terminal species (reactants and products) T 1, T 2,.,T n.Thus, the mechanism is described by a set of p elementary .

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.

Improve batch reactor temperature . - Chemical Processing

The jacket and reactor temperature relationship includes integrating dynamics, making controller tuning less intuitive than for self-regulating (e.g., flow) loops. Complex control systems have been developed to handle various reactor hardware, specific types of chemical reactions and production constraints [1].

Chemical reactors - Essential Chemical Industry

Chemical engineers are designing reactors where the fluids to be reacted are oscillated inside a reactor with baffles at frequencies between 0.5 and 15 Hz with amplitudes in the range 1 to 100 mm. This allows for very effective mixing of the reactants and also for heat to be transferred to the surroundings.

Selective catalytic reduction - Wikipedia

Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NO x with the aid of a catalyst into diatomic nitrogen (N 2), and water (H 2 O).A reductant, typically anhydrous ammonia, aqueous ammonia or urea solution, is added to a stream of flue or exhaust gas and is adsorbed [citation needed] onto a catalyst.

Chemical Equilibrium in Chemical Reactions

Chemical equilibrium is the condition which occurs when the concentration of reactants and products participating in a chemical reaction exhibit no net change over time. Chemical equilibrium may also be called a "steady state reaction." This does not mean the chemical reaction has necessarily stopped occurring, but that the consumption and formation of substances have reached a balanced condition.

The reactor is the most influential unit operation in many chemical processes. Reaction systems and reactor design often determine the character of the flowsheet. However, research in reactor network synthesis has met with limited success because of nonlinear reaction models, uncertain rate laws, and numerous possible reactor types and networks.
