Envitech Syngas Cleaning Systems Used for Waste-to-Energy

The Envitech syngas cleaning system provides emissions control for waste-to- energy production at a lumber facility. A small gasifier (< 1 MW) is used to gasify wood chips that are a byproduct of sawmill operations. The syngas produced by the gasifier is combusted in a dual fuel internal combustion engine (ICE) to produce electricity. Waste energy from the ICE in the form of hot water is used for drying lumber in an on-site drying kiln.

During biomass gasification, various pollutants may be produced depending on the type of gasifier and the composition of the biomass material. The pollutants can include sub-micron particulate matter, tars, ammonia, HCl. and sulfur compounds. These pollutants must be removed before the biomass is combusted. The Envitech syngas cleaning system captures these pollutants, providing a reliable syngas cleaning system for biomass waste-to-energy plants.
