Syngas-related industries

Raman Optograf Analyzer for gas composition without sampling valve, column and carrier gas

Measuring composition for optimizing syngas production, process intermediates and end products

Raw syngas in primary reformer outlet

Raw syngas is the first intermediate product; measurement of the components H2, CO, CH4 and CO2 are used to monitor the H2 and CO2 and allow optimization of the steam/carbon ratio for controlling the reformer.

Traditional approach

Gasifier outputs are dirty streams – sampling and speed of response are main concerns in this process of hazardous and pressurized gases. Typically applied technologies like Process GC or Mass Spectrometry (MS) require transporting and conditioning the sample at both the sample tap and sample conditioning panel close to the analyzer.

Specifically, in this application, the use of a Dynamic Reflux Sampler (DRS) or alternative liquid and particulate removal system is mandatory. Protecting the GC or MS analyzers from liquid carry-over is the main challenge as this can damage columns in a GC or the ionization chamber in a MS.

Our solution

Continuous measurement using a Raman Optograf Analyzer and the OptoDRS™ sample conditioning.

Multi-component analysis

H2S, NH3, CO2, CO, H2, N2, CH4, CH3OH, C2H6, C3H8, C4H10

Unique benefit

  • Robust spectroscopic capability to measure simultaneously all syngas components, including H2 and N2

  • Front‑end sampling to deal with particle-laden or steam-saturated samples, ensuring no liquid carry-over

  • Saves cost on carrier gas and calibration efforts

  • Improved safety, since no process gas is transported to a shelter analyzer house

Applications

  • Measuring composition for optimizing syngas production, process intermediates and end products
