OGI for hydrocarbons gas leaks

REQUEST INFO

Mileva 33 Ex is SENSIA’s latest model of Optical Gas Imaging (OGI) for the detection of fugitive emissions of hydrocarbon gases (HxCx). It integrates a spectrally optimized high-resolution cooled detector that increases the detection sensitivity for leaks down to 0.4 g/h of CH4.

Mileva 33 Ex by PASSIVE IR absorption can detect all the hydrocarbons and VOCS (including CH4) on the 3.2 – 3.4 μm wavelength.

The detection distance is higher than 100m and VOC leak images and videos can be recorded and played inmediately.

Considerations related to the MDLR determination for the SENSIA OGI’s

  • Leak observation is done at distance short enough to ensure the leak resolvancy with various pixels
  • Characterization test conditions:

o    Background temperature controlled

o    Outlet Orifice Diameter= ¼’’

o    CH4 diluted with N2 (25% methane)

  • Gas Detection condition using High Sensitivity Mode

The following table shows the gas detection capabilities of the SENSIA OGI’s under real scenarios conditions.

Minimum Methane mass flow rate for detection Detection distance Detection distance
0,3 g/s 50 m 125 m
0,5 g/s 100 m 250 m

This table specifies the minimum mass flow rate, for methane as the reference gas, that can be detected by each technology from a certain distance.

Innovative capabilities assembled under a single control software

Enhanced mode

RedLook is capable of automatically coloring the gas to facilitate the identification. With SENSIA OGI cameras, you can scan broad sections of equipment rapidly and survey areas where traditional contact measurement tools cannot access.

Quantitative OGI

Placing the OGI on a tripod activates automatic quantification of Methane leaks: fast, accurately and safely.

Mileva for leaktightness verification

Mileva 33 Ex has a new design, a 5-inch touch screen and runs under RedLook, the most powerful and intuitive software for gas visualization. This control and analysis software unfold the full potential of Mileva 33 Ex Optical Gas Imaging.

Mileva 33 Ex has the main international certifications in temperature, humidity, vibration, dust and water intrusion and hazardous environments. With this new OGI, the operator can inspect locations under severe restrictions, that generally impede SMART Leak Detection and Repair operations.
