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.
