Petrochemicals / olefins / ethylene
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 ppmv.
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.
SpectraSensors' TDL analyzers respond to concentration changes in seconds versus minutes, with repeatability comparable to GC
Optimization of H2 utilization
