Petrochemicals, olefins and ethylene
High accuracy gas analysis 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.
The 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.
SpectraSensors TDL analysers respond to concentration changes in seconds rather than minutes, with repeatability comparable to GC.
Optimization of H2 use.
Typical analytes and measuring ranges
Analyte: C2H2 - Range: 0-5 to 0-3000ppmv
Analyte: H2O - Range: 0-10ppmv
Analyte: NH3 - Range: 0-5ppmv
Analyte: CO2 - Range: 0-500ppmv
Analyte: H2S - Range: 0-500ppmv
Continuous, analyte-specific measurement versus batch measurement of multiple components.
Fewer acetylene conversion unit upsets with less product loss to flare.
