High accuracy gas analytical solution for process quality improvement and fast ROI in olefin plants

Measuring impurities in C₂ streams fraction to prevent C₂ splitter contamination and prevent going to flare due to not meeting ethylene product specifications.

Acetylene C₂H₂ in C₂ ethylene

Control of hydrogenation conditions in the acetylene converter. Measuring range starting from 0 to 5 ppm_v.

Traditional approach

Speed of response of gas chromatographs (GC) for acetylene is not rapid enough to prevent upset conditions. Potential to contaminate the C₂ splitter or process gas which then must be sent to flare with loss of revenue.

Our solution

SpectraSensors' TDL analyzers respond to concentration changes in seconds versus minutes, with repeatability comparable to GC
