Abstract

The industry’s dependency on fossil fuel in Indonesia is still very high and may cause air pollution that is harmful to environment. The government’s regulation to prevent air pollution problem through KEPMENLH number 13 of 1995 on dealing with gas emission from stationary source must be monitoring the flue gas emission measurement on the stack. But the main problem during measurement is fluctuated measurement result because of cyclonic and less uniform flue gas flow. In case of reducing the Relative Standard Deviation is by installing a flow straightener inside the stack. This research has four measurement conditions such as stack without flow straightener, stack with flow straightener level 0.75D, 1D and 1.25D from the bottom interference of the stack. From this work results that the use of flow straightener can reduce the Relative Standard Deviation (RSD) as in NO2 which tend to decrease, in condition of stack without flow straightener has 8.63265 % of RSD, stack with flow straightener respectively are 0.75D has 8.39012 % of RSD, 1D has 3.746% of RSD and 1.25D has 0% of RSD. However, the installation of flow straightener could increase the isokinetics percent in particulate sampling. The isokinetics percent of the stack without flow straightener, with flow straightener 0.75D, 1D and 1.25D respectively are 94.88 %, 114.83 %, 134.48 % and 148.66 %.
