Abstract


Producer gas from biomass gasification consists of tar from pyrolysis process which is not
degradation thermal well before out from the reactor. In fact tar is a serious problem that must be
considered in the process of gasification, especially for an internal combustion engine
application.Gas cleaning system is one the methods to reduce the tarproduced in gasification
process. The research purpose which is to design a purify device for the producer gas which is
integrated and also to know the influence of gas speed and water debit towards tar getting as
measurement research of IGCS. The research does by using reactor with diameter dimension 0,8 m
and 1,5 m high. The result of this research getting the gas speed for the cyclone about 2,4 m/s and
flow of water in venturi scrubber 3,3 l/min, collected tar is 12 gram with 66,67 % cyclone efficiency
and 10 gram with 44,44 % venturi scrubber efficiency. Meanwhile, rotary separator gas speed
about 2,6 m/s, it is able to reduce 10 gram tar with 55,56 % efficiency. The result from combine
testing show that the tar left in producer gas is only 210 mg/m3 with 94,4 % efficiency.
