Abstract/ Foreword

The paper’s purpose is to quantify the measurement consequences in the purge test of equipment protected with the “p” type of protection. In order to achieve this objective, the authors involved a simulation process for a pressurization enclosure. The simulation was conducted, in the first stage, without measurement to obtain a reference after that simulation was conducted for scenarios involving sampling separately for each measurement point.
The first part of the paper presented the risks of explosion and pressurized enclosure as a protection type. The use, production, processing, and storage of petroleum products and gases generate atmospheres that can ignite or even cause explosions, resulting in serious losses.
In the second part, the simulation model for obtaining test gas concentrations was proposed and presented, as well as the conditions imposed in the simulation model for the purpose of simulation. Within this approach, the influence of the measurement process (by sampling) on the test as a whole was investigated.
The prevalent conclusion is that the measurement process with sampling at the configured parameters influences the purging test and this effect manifests differently on the considered measuring points. The implemented and presented method allows the classification of pre-set measurement locations as critical points. The magnitude of the deviation underlines the need to return the gas mixture due to the sampling involved in the measurement process.
