Process Engineering

IP Facilities

The department has many analytical means (mass spectrometer, gas chromatography, inductively coupled plasma mass spectrometry, high performance liquid chromatography) and aeraulic metrology (PIV, LDA...). It also relies on the use of new technologies (3D scanner, real-time sensor networks, video...). It has test benches for the study of source suction systems, ventilation, reactors and separators from the laboratory scale up to pilot or even industrial sizes when necessary.
 

Spatial and temporal analyses of chemical exposures

The laboratory's mission is to identify and evaluate occupational situations presenting or likely to present problems of exposure to chemical pollutants and to specify the origin of these problems. To do so, it relies on important analytical skills and means (gas chromatography, mass spectrometer, High Performance Liquid Chromatography...) and on the use of various technologies after having adapted them to the field of prevention: specific or non-specific chemical exposure detectors, video, trajectography... This mission of evaluating chemical exposures is generally based on the identification of problems, the analysis of needs, the search for internal or external collaborations, the global and local evaluation of exposures in work situations and the identification of the phenomena at the origin of exposure problems.

Aeraulic engineering

The laboratory's mission is to propose preventive solutions, based on ventilation, to control employee exposure to hazardous substances and heat. Its main activities concern the development of methods that can be used for the evaluation and design of air purification systems for industrial and tertiary sector workstations and premises. Particular attention is paid to the evaluation and reduction of emissions of hazardous substances from machinery (portable machines, public works machinery, additive manufacturing, etc.). The laboratory takes into account the reality of field situations in its approach: multiple and interacting capture and ventilation equipment, effect of external and internal disturbances and interferences on the efficiency of systems (intermittent actions of wind, air currents, pressure variations, door openings ...) based on aeraulic metrology on site and in the laboratory (PIV, LDA ...) and simulations of computational fluid mechanics.
 

Process and purification of pollutants

The laboratory's mission is to search for prevention solutions involving the design of industrial installations and equipment : 

• processes using chemical products, 
• treatment processes for captured pollutants, 
• breathing apparatus. 

The aim is to evaluate their performance from a health and safety point of view based on laboratory and on-site studies. The laboratory then proposes innovative solutions or technically and economically acceptable improvements, or defines the limits for the use of protective means such as personal protective equipment. The level of action can go as far as the implementation of semi-industrial pilot projects in order to validate on site and in real conditions the effectiveness of the prevention tools developed.
