A plasma gasifier is an oxygen starved vessel where various feedstocks can be gasified using the very high temperatures achievable with plasma. Rather than being combusted, the heat breaks the feedstock down into elements like hydrogen and simple compounds like carbon monoxide and water. The gas that is created is called synthesis gas or “syngas”.
The syngas created in the gasifier, which contains dust (particulates) and other undesirable elements like mercury, undergoes a clean-up process to make it suitable for conversion into other forms of energy including power, heat and liquid fuels. The syngas clean-up process is tailored to meet the requirements of each project. In most cases, especially where municipal solid waste (MSW) is the feedstock, the syngas clean-up will include particulate removal, sulphur removal and mercury/heavy metals removal.
The Plagazi Process making hydrogen from waste is an attractive alternative for the society and a good business case.
