Problems solved by technology

Moreover, if the diluent gas, which is almost oxygen-free, itself contains flammable substances such as hydrogen, the mixture exiting the analyzer at the outlet itself presents a risk of explosion if it comes into contact with air or, more generally, with combustion-supporting substances

Embodiment Construction

[0051] refer to Figures 1 to 5 The analyzer 1 according to the present invention will be described. The analyzer 1 is used, for example, to analyze a fluid 3 from an oil refinery.

[0052] The fluid 3 is, for example, a mixture of gases produced by petrochemical methods, which gas mixture includes the substance to be analyzed, such as benzene. Benzene is a flammable substance with an LEL of 1.2%.

[0053] Analyzer( figure 1 ) includes a box body 5, a detector 7 located in the box body 5, an air source 9, and an injection nozzle 11 fluidly connected to the air source 9 at the air inlet and receiving the fluid 3 to be analyzed, the injection nozzle 11 It is connected to the detector 7 at the gas outlet through the box body 5. The analyzer 1 advantageously comprises a modular interface 13 on which the tank 5 and the injection nozzle 11 are mounted.

[0054] The analyzer 1 in turn comprises an assembly 15 for supplying and controlling the air source 9 , the injection nozzle ...

Abstract

An analyzer 1 for analyzing a fluid 3 containing at least one substance to be analyzed and at least one flammable substance and a corresponding method, the analyzer 1 comprises: a gas source 9 providing a dilution gas flow, for Injection nozzle 11 for introducing a plurality of samples of said fluid 3 into said dilution gas flow and generating a gaseous flow, and detector 7 for analyzing the gaseous flow, wherein: the gas source is used to contain a gaseous flow that can help Conveying a dilute gas stream of material combusted by said flammable substance, preferably a stream of air, said injection nozzle being configured to introduce a plurality of samples introduced into said fluid into the diluent gas such that the gaseous stream The average volume fraction of the fluid is less than 1 / 2000 and preferably less than 1 / 20000, and the detector comprises at least one microsensor for detecting the analyte.

Description

technical field [0001] The invention relates to an analyzer capable of analyzing a fluid containing at least one substance to be analyzed and at least one flammable substance, the analyzer comprising: [0002] gas source, providing a diluent gas flow, [0003] injection nozzles for introducing samples of fluid into the dilution gas stream and generating a gaseous stream, and [0004] A detector is used to analyze the gaseous stream. [0005] The invention also relates to a method for analyzing a fluid containing at least one substance to be analyzed or an "analyte" and at least one combustible substance, which may be the analyte or other substance. Background technique [0006] The invention is particularly suitable for the analysis of fluids at risk of explosion or in explosive atmospheres. For example, the invention is suitable for analyzes performed in the petroleum industry, chemistry and petrochemistry. [0007] Explosive atmospheres or "ATEX" (ATmosphère EXlosible)...
