Description

CHEMICAL REACTOR
The present invention relates to a chemical reactor.
As is known, presently, manufacture of small chemical reactors, particularly for generating hydrogen, suffers drawbacks related mainly to their practical construction, their reliability and their management.
With current reactors there are in fact considerable difficulties in finding stable conditions of chemical and thermodynamic equilibrium both in processes with highly endothermic reactions, such as for example the so- called "steam reforming" reaction, and in processes with highly exothermic reactions, such as for example so-called "water gas shift", "prox" or "methanation" reactions.
Moreover, in the case of reactions which occur at high temperatures (900-1000 0C), extreme thermal and mechanical stresses are added to these problems and compromise the durability, and therefore the structure of the reactor and the performance of the catalyst.
The aim of the present invention is to devise a solution to the problems noted above by providing a chemical reactor whose dimensions are considerably reduced and which allows precise and easy control of the reaction temperature.
Within this aim, an object of the present invention is to provide a chemical reactor which can ensure a uniform distribution of the temperatures inside the reactor.
Another object of the present invention is to provide a chemical reactor which, thanks to its particular constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
Still another object of the present invention is to provide a chemical reactor which can be obtained by means of commonly commercially available elements and materials and is also competitive from a merely economical standpoint.
This aim and these and other objects, which will become better apparent hereinafter, are achieved by a chemical reactor according to the invention, comprising at least one reaction duct which has an inlet for the inflow of the reagents and an outlet for the discharge of the reaction products and accommodates a catalyst along at least one portion of its longitudinal extension, characterized in that heat exchange means, adapted to exchange heat with the reagents in their transit through said reaction duct, are arranged within said reaction duct.
Further characteristics and advantages of the invention will become better apparent from the description of a preferred but not exclusive embodiment of the chemical reactor according to the invention, illustrated by way of non-limiting example in the accompanying drawings, wherein;
Figure 1 is a partially exploded perspective view of the chemical reactor according to the invention;
Figure 2 is a perspective view of the chemical reactor according to the invention; Figure 3 is a partially cutout perspective view of the chemical reactor according to the invention;
Figure 4 is a longitudinal sectional view of the chemical reactor according to the invention. Ways of carrying out the Invention With reference to the figures, the chemical reactor according to the invention, generally designated by the reference numeral 1 , comprises at least one reaction duct 2, which is provided generally with an inlet for the inflow of the reagents and with an outlet for the discharge of the reaction products. Along at least one portion 2a of its longitudinal extension, the duct 2 accommodates a catalyst 3, which is permeable to the flow of the reagents that flow within the reaction duct 2 and can vaiy according to the type of reaction to be obtained.
By way of example, the catalyst 3 can be provided, in a per se known manner, on several media, such as for example pellets, meshes or others, and with a different chemical composition depending on the type of reaction.
The peculiarity of the invention resides in that heat exchange means are arranged inside the reaction duct 2 and are adapted to exchange heat with the reagents in their transit through the reaction duct, so as to ensure perfect control of the reaction temperatures.
More particularly, the heat exchange means are arranged advantageously so as to affect at least one passage section 2b of the reaction duct 2, so that they can be struck uniformly by the flow of reagents, thus preventing the formation, within the reaction duct 2, of regions at lower or higher temperatures with respect to the optimum temperatures for the reaction being performed.
Conveniently, in the illustrated embodiment, the heat exchange means are provided by means of one or more exchanger tubes 4, inside which a temperature control fluid flows; such fluid can be hot or cold, depending on whether the reaction is respectively endothermic or exothermic, and can be constituted by any suitable fluid, such as for example water, glycol, combustion gases and so forth.
As can be seen more clearly in Figure 2, each exchanger tube 4 has its own delivery connector 4a and its own return connector 4b, which protrude from the reaction duct 2 in order to be connected to a suitable device for circulating the temperature control fluid inside the exchanger tubes 4.
Advantageously, each exchanger tube 4 is arranged in a circular spiral substantially concentrically to the axis of the reaction duct 2 and can be made of weakly alloyed stainless steel with a cross-section whose type and size can vary according to the requirements.
Due to their particular spiral shape, the exchanger tubes 4 allow to provide optimum heat exchange with the reagents while they pass through the reaction duct 2 and further allow to achieve a uniform distribution of the reagents within the reaction duct 2, so as to also optimize the reaction process.
It should be noted that the exchanger tubes 4 can be fixed to the body of the reaction duct 2 stably, for example by welding, particularly where the reaction temperatures reach high values, for example higher than 700 0C, or detachably, by means of suitable sealing systems, such as gaskets or the like, so as to facilitate the operations for maintaining or replacing the catalyst 3.
Preferably, inside the reaction duct there are also means for smoothing the flow of the reagents, which are designed to increase the uniformity of the distribution of the reagents within the reaction duct 2.
In the embodiment shown in the figures, such means are constituted by one or more diffuser partitions 5, which are interposed along the reaction duct 2 and are constituted advantageously by a respective finely perforated plate 6 which is arranged transversely to the reaction duct 2. In order to better control the flow of reagents that passes through the exchanger tubes 4, the diffuser partitions 5 are conveniently arranged upstream and/or downstream of each exchanger tube 4 along the direction of flow of the reagents along the reaction duct 2.
Advantageously, the reaction duct 2 can be coupled to another reaction duct of the same type which is laterally adjacent thereto.
In greater detail, it is possible to connect one another a plurality of reaction ducts 2 according to a series arrangement, so as to allow the flow of the reagents to pass in succession through the reaction ducts 2 and the corresponding heat exchange means, one after the other, or according to a parallel arrangement, so that each reaction duct 2 can be crossed by independent flows.
From what has been described above, it can be seen that the invention is capable of achieving its intended aim, since the presence of heat exchange means integrated within the reaction duct allows to reduce considerably the dimensions of the reactor with respect to the background art and to ensure at the same time a uniform distribution of the temperature inside the reaction duct.
Moreover, the possibility to vary the number of exchanger tubes and the possibility to assemble a plurality of reaction ducts in series or in parallel, depending on the type of reaction to be obtained, allows to maintain easy control over the exchanged thermal power levels and to perform accordingly a precise adjustment of the reaction.
All the characteristics of the invention indicated above as advantageous, convenient or the like may also be omitted or be replaced with equivalents .
The individual characteristics presented with reference to general teachings or particular embodiments may all be present in other embodiments or may replace characteristics in these embodiments.
The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
In practice, the materials used, so long as they are compatible with the specific use, as well as the shapes and dimensions, may be any according to requirements. All the details may further be replaced with other technically equivalent elements.
