| Summary: | Biomass gasification process produces synthetic gas (syngas) products
which are CO, H2, and CH4 that can be used as an energy source. Byproducts such
as tar and particulates can also be produced in this gasification process. The
byproduct can be a problem for gasification process because it can reduce the
quality of the syngas. Tar and particulates have to be separated from the syngas
components as well as the cooling gas to condense the water vapor carried in the
syngas is needed to improve the quality of gas production. One of the alternatives
for the purpose is utilizing spiral pipe condenser to separate tar and particulates
and also the cooling gas. This study was conducted to analyze the performance of
the cooling and cleaning of the syngas by using spiral pipe condensation.
The study was conducted by giving cooling water discharge treatment with
discharge variations (0, 0.07, and 0.2 L / sec), and a spiral pipe treatment with
diameter variation (0.75, 1, and 1.25 inches). Performance parameters measured
were changes in temperature and mass of tar that can be separated with a spiral
condenser pipe. To determine the effect of the treatment given to the measured
parameter, there were used 2 factor of factorial experiment using analysis of
variance (ANOVA).
The results showed that variations in pipe diameter spiral significantly
affected syngas cooling process, the larger diameter spiral pipe, the greater the
temperature of syngas drops. Cooling water discharge variations did not affect the
decrease in temperature syngas. Variations diameter spiral pipe and discharge of
cooling water significantly affected syngas cleaning process of tar and
particulates. For treatment interaction of diameter spiral pipe with cooling water
discharge did not significantly affect the cooling process and syngas cleaning. The
greatest temperature reduction was achieved in variation of 1.25 inch diameter
pipe with cooling water flow of 0.07 L / sec was equal to 33.9 oC. The greatest
variation of the cleaning tar and particulate was achieved at 1.25-inch diameter
pipe with cooling water flow 0.2 L / sec which was equal to 256.7 grams. |
