Abstract:
A by-product of biomass gasification is tar in the product gas. It can be removed by a scrubber operated with rapeseed methyl ester (RME). There is, however, little information on the suitability of other fatty acid methyl esters (FAME). FAME obtained from palm, rapeseed, soybean, sunflower and used cooking oil were mixed with water by a defined air flow in gas-washing bottles. Water is condensed in the scrubber as well and should be separated from the FAME. These experiments were repeated with ammonium carbonate or phenol added as these substances are found also in minor amounts in the scrubber liquid. After mixing, the separation of FAME and water was evaluated. Ammonium carbonate slowed down the phase separation and saponification took place. The addition of phenol did not show a distinct effect. The best separation was obtained with RME and sunflower methyl ester, whereas palm oil methyl ester showed the worst phase separation performance.
