| Summary: | Palm Oil Mill Effluent (POME) is a liquid waste of oil palm factory that pollutes the
environment but is very useful as a raw material for producing biogas. POME
processing has advantages to meet environmental requirements and to produce
commercialized products. Although there are already enough biogas systems installed
in oil palm factories, they are not designed optimally because it involves many
parameters and quite complicated process. The purpose of this study is to obtain an
anaerobic system utilizing POME at an oil palm plant in Muaro Jambi, Indonesia. The
optimization is based on simulation results of some process parameters to produce
maximum bio-methane gas discharged at the highest CH4 concentration. The processes
occurring in the digester are stoichiometrically modelled for several variations of TSS
(2-4%), temperature (30-60oC), operating pressure (1-2 bar), as well as digesting stages
(1 and 2 stages). Pressure in the scrubber was varied between 9 and 12 bar, while the
water flow was 1,000-15,000 kg/hour and had 3-12 stages. Calculations were
performed using Aspen Plus Software. Based on this research finding, the optimum
design and condition is found for 2-stages digestion where TSS = 4% and 1 bar, with
temperature at first and second digester is 60oC and 42oC, respectively, which produces
7,725 kg/day biogas. The optimum methane purification is found in 5-stage scrubber
at 10 bar, with water discharge of 11,000 kg/hr, which produces 7,627 kg/hour CH4
with 97.24% methane content. |
