Abstract
The invention relates to a procedure for determining the risk of flammability of a mixture of two reactive gases A, B, in an inert or base gas, which includes: a step of determining, in the flammability diagram for the A/B/base gas mixture, the change in the composition of the mixture in order to determine whether or not the composition has passed through the flammability region of the flammability diagram, when A is firstly injected into the inert or base gas to form a first mixture and then B is injected into the first mixture in order to form the final mixture; a step of comparing the mixing time, should the region have been passed through, with the chemical induction time for the mixture.
Claims20
A process for determining the risk of flammability of a mixture of at least two reactive gases A, B, in an inert or base gas, or the order of mixing of these reactive gases into the inert or base gas, the process comprising:
- a step of determining whether the composition of the mixture, during its formation, passes through a flammability region in a ternary diagram of the A/B/inert or base gas mixture when the mixture is produced according to a first mode in which A is first mixed into the inert or base gas to form a first mixture and then B is mixed into the first mixture to form the final mixture;
- a step of determining a first transit time through the flammability region of the ternary diagram when the mixture is produced according to the first mode;
- a step of comparing the first transit time with the chemical induction time of the mixture or of the stoichiometric mixture;
- and
- a step of determining the risk of flammability or the order of mixing based on a review of data received from the previously recited steps.
