Benefits of technology

The technical effect of this patented method described in the patents relates to improving control over reaction processes that involve opening up an enclosed space called a closed vessel containing certain substances under specific conditions such as temperature, pressure, etc., without requiring continuous monitoring during operation. This results in improved efficiency and accuracy compared with traditional methods like batch types.

Problems solved by technology

The technical problem addressed in this patented technology is how to efficiently control or adjust the flow rate of an exchanging liquid used during chemical redox processes within a plate type opening reactor without affecting its performance due to excessive temperatures caused by overheating certain parts inside it's vessel walls.

Embodiment Construction

[0054]Reference is made initially to FIG. 1 which is a diagram of an open or continuous reactor comprising a stack of plates 20, 21, 22, 23 which define parallel chambers between one another. The plates 21 and 22 are referred to as “transition” plates and they define between them a reaction chamber 24 having a reagent feed point 25a and one or more feed points 25b for one or more other reagents, and an outlet point 26 for the product(s) of the reaction. The plates 20 and 23 are adiabatic plates and they co-operate with the plates 21 and 22 to define a left side chamber 27 and a right side chamber 28 for circulating a heat exchange utility fluid, each side chamber 27, 28 having an inlet 29 and an outlet 30 for the utility fluid.

[0055]The utility fluid which circulates in the left side chamber 27 may be identical to or different from that which circulates in the right side chamber 28, and the utility fluid that is commonly used is water or ethylene glycol.

Abstract

A method of optimizing a chemical reaction in a plate-type open reactor, the method consisting in:
    • establishing a dynamic model of the reactor for a given reaction on the basis of a model of the reactor and its heat exchanges;
    • applying an integration software tool to the dynamic model in order to solve the above-mentioned equations;
    • determining and optimizing a set of dimension and/or operation parameters of the reactor on the basis of evaluating targets to be achieved, constraints to be complied with, and variable data for the reactor and/or the reaction;
    • building a plate reactor of the said type accordingly to the set of optimized parameters; and
    • doing measurements of physical parameters during the execution of said reaction in the built reactor, for validating its operation.
