Abstract
The high quality of syngas from gasification and cleaning systems can be utilized for energy generation or commodity chemicals. To evaluate the quality of syngas from waste gasification and to obtain design factors for commercial scale, we identified the characteristics of particles depending on the cleaning units in pilot scale. The particle size distribution, amount of particles and heavy metals were analyzed at gasifier and each cleaning unit which are quenching scrubber, venturi scrubber, neutralization scrubber, desulfurization scrubber, and wet electrostatic precipitator. As a result, about 99.98 % of the particles were removed through 5 cleaning systems, from 51,226 mg/Nm3 at gasifier to 12 mg/Nm3 at WESP, and were ostensibly undetectable. Moreover, the minimum size of particles that could be eliminated was different depending on wet cleaning systems. The particle size at 90 % in the cumulative was generated up to 24.029 µm at the gasifier and the removed particle size distribution at WESP ranged from 0.370 to 12.795 µm. From the particulate matters point of view, the syngas from waste gasification with cleaning systems can be properly utilized for energy recovery systems.
