Jean-Pierre Corriou, in Coulson and Richardson's Chemical Engineering (Fourth Edition), 2017. Linear quadratic Gaussian control of a chemical reactor. The same chemical reactor as for LQ control is used to evaluate LQG control. The same set points are imposed. In this case the theoretical states describe the behavior of the plant but noisy measurements are used as process outputs.

Fixed-Bed Reactors - Uni Stuttgart

Catalytic fixed-bed reactors are the most im­ portant type of reactor for the synthesis of large­ scale basic chemicals and intermediates. In these reactors, the reaction takes place in the form of a heterogeneously catalyzed gas reaction on the surface of catalysts that are arranged as a so­ called fixed bed in the reactor. In addition to the

Using a fluidized bed reactor (Fig. 6.3) resolves some of the problems faced with a fixed bed reactor.This particular reactor offers a much more enhanced mass and heat transfer and minimizes temperature gradients throughout the reactor [64].The mass and heat transfer are improved due to better mixing of the catalyst with the fluid, which provides a greater surface area for the reaction to occur.

May 01, 2006 · This reiterates that plug flow can never be obtained in a single tank. Theoretically plug flow could be achieved by two methods: a) using a number of CSTRs in series, or b) operating high net flow Reynolds numbers in a tubular reactor. approaching ideal. Achieving the ideal plug flow requires an infinite number of CSTRs, which is impossible.

From Batch to Continuous Chemical Synthesis—A Toolbox .

A toolbox approach for the transfer of batch to continuous chemical synthesis is presented. The approach considers reaction kinetics (Type A, B, C), reacting phases (single phase, liquid–liquid, gas–liquid and liquid–solid), and the reaction network (parallel and consecutive reactions) in order to select the most appropriate reactor module (Plate, Coil, or CSTR) for continuous operation.

The Plug Flow Reactor. The Plug Flow Reactor (PFR) is used to model the chemical transformation of compounds as they are transported in ``pipes.'' The ``pipe'' may represent a river, a region between two mountain ranges through which air flows, or a variety of other conduits through which liquids or gases flow.
