Syngas-related industries

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

Measuring composition for optimising 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 optimisation of the steam/carbon ratio for controlling the reformer.

The traditional approach

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

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 analysers from liquid carry-over is the main challenge as this can damage columns in a GC or the ionisation chamber in a MS.

Our solution

Continuous measurement using a Raman Optograf analyser and OptoDRS sample conditioning.

Multi-component analysis

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

The benefts:

  • 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 as no process gas is transported to a shelter analyser house.

Applications

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