New Portable Syn-Biogas Pre-Treatment Unit

The new ETG (Italy) Portable syngas pre-treatment unit meets the requirement in gas analysis to have a clean gas to feed the analyser, removing dust/tar/moisture to obtain a clean and dried sample for analysis.

Syngas frequently contains moisture, particulate, and even corrosive gases. It is important to remove these contaminants from the sample gas before analysing it.

In some cases, the produced gas contains a variety of contaminants that should be removed from the sample prior to entering the analyser. Gasification plants that have municipal waste as their feed stock are frequently in this category.

The Scrubber water wash system (bubbler) thoroughly mixes the sample and runs it through a specialised column of water. This dissolves any water-soluble contaminants and will eliminate any residual solids from the sample.

The unit is fully transportable and allows the direct inlet from the process gas (reactor, pyrolysis, coal, dirty process) thanks 3 refillable water scrubbers, 1 fine filter with replaceable 0.3µm filter element for tar removal, heat exchanger made of PVDF, Semi-conductor (peltier-effect) cooled, electronic controller, temperature setpoint at fact. +5° C, built-in heat exchanger temperature display, micro fine dust filter with fiberglass filter element, built-in peristaltic pump for continuous removal of condensate, diaphragm sample pump PVDF/FPM, flow rate < 2Nl/min interlocked with over/under temperature alarm, “Pump” and “Alarm” status display, flowmeter with needle valve , LED indicator lamp, blinking when system is ready for use Material in contact with sample: PVDF, FEP, FPM, SS316.
