Hot and Cold Gas Cleaning

Conditioning of syngas can be accomplished through hot or cold gas cleaning technologies. The cost of syngas conditioning can be a significant portion of the cost of syngas production, hence reducing cost of syngas conditioning is critical. Hot gas cleaning technologies use high temperature and catalysts to crack tar molecules into gaseous compounds, which can also improve the energy content and composition of the syngas. Cold gas technologies use solvents such as water, acetone, isopropanol, and oil to scrub tar and other contaminants from the gas.
