Gasification offers a combination of flexibility, efficiency and friendliness to the environment that these are important in meeting the energy needs to overcome impurities or contaminants and organic particles,such as tar. In fact tar is a serious problem that must be considered in the process of gasification, especiallyfor an internal combustion engine application. Gas cleaning system is one the methods to reduce the tar produced in gasification process. This study aims to evaluate the content of tar before and after the ventury scrubber. Gasification air flow rate was 189.6 lpm; the water flow rates through the venturi scrubber were in therange of 10 to 30 lpm. The tar contents of the produced gas before and after cleaning were 675 and 125 mg/m3, respectively.
