An efficiency of the biofilter system to reduce total VOCs concentration of light cracker bottom storage tank
Abstract:
The objective of this study was to design and construct the biofilter system to
eliminate the volatile organic compounds (VOCs), which cause the nuisance odor.
An experimental research design was employed for this study to test the
efficiency of a designed and constructed biofilter system in reducing the concentration
of total VOCs, which passed through the byproduct Q-1516 tank which is type of light
cracker bottom tank (LCB). The experimental data were analyzed by descriptive
statistics with Mean and S.D., with a one sample t-test to determine the efficiency of
biofilter system.
The findings revealed that the average efficiency of the biofilter system was
88.87 %. This is lowly close to the 90% prediction of efficiency made in the initial
hypothesis.
The recommendations of this study are that, it should be additionally studied
on environment that affects to the efficiency of the biofilter system should also be
studied more information on systemic efficiency with averaging of data should be
introduced. Additionally, the growth stages of microorganism-lag phase, log phase,
stationary phase and growth phase-should be studied.
