Syngas-related industries

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
