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.
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.
