The present invention relates to a distribution device intended for a gaseous effluent produced by a chemical reaction, comprising at least two inlet ways and two outlet ways. This device comprises at least one closed-loop line divided into four sections by four controlled sealing elements, and each one of said four ways communicates with a single section so that the inlet ways are connected to two opposite sections and said outlet ways are connected to the other two sections.

1. A distribution device notably intended for a gaseous effluent produced by a chemical reaction, comprising at least two inlet ways and two outlet ways, characterized in that it comprises at least one closed-loop circuit divided into four sections by four controlled sealing elements, in that each one of said four ways communicates with a single section so that the inlet ways are connected to two opposite sections and said outlet ways are connected to the other two sections. 2. A device as claimed in claim 1, comprising two closed-loop lines and said outlet ways communicate together two by two so as to form a distribution device with four inlet ways and two outlet ways. 3. A device as claimed in claim 1, wherein each of said sealing elements comprises a conical needle cooperating with a sealed seat. 4. A device as claimed in claim 1, wherein each of said sealing elements is activated by a pneumatic jack operator. 5. A device as claimed in claim 1, wherein said closed-loop circuit comprises four rectilinear lines arranged in the shape of a quadrilateral, said sealing elements being arranged substantially at the four corners of said quadrilateral. 6. A device as claimed in claim 1, wherein the sealing elements are suited to an effluent pressure and temperature that reach 250 b and 400° C. respectively. 7. Equipment intended for measurement on an effluent resulting from a chemical reaction taking place in a reactor containing a catalyst, and comprising: at least two reactors, analysis and measuring means intended for said effluent, means intended for automatic monitoring and control of the chemical reaction and of the analysis and measurement cycle, and the distribution device as claimed in claim 1, said distribution device supplying said analysis and measuring means alternately with the effluents from the two reactors in order to perform two analysis and measurement cycles on two reactions progressing in parallel.
