Abstract

Pengolahan anaerob merupakan teknologi efektif yang murah untuk mengolah limbah cair kelapa sawit (POME) menjadi biogas yang dapat dijadikan bahan bakar atau listrik. Yield biogas dapat ditingkatkan dengan menerapkan teknik pretreatment limbah POME sebelum menuju digester. Umumnya, teknik pretreatment ini adalah tahapan hidrolisis yang merupakan tahap pertama dari produksi biogas. Tujuan dari pretreatment ini untuk memecah padatan atau gumpalan komponen agar lebih mudah dicerna oleh bakteri. Studi ini berisi ulasan perbandingan keunggulan dan kelemahan beberapa metode pretreatment terkini termasuk dengan evaluasi biaya operasional yang sesuai untuk diaplikasikan pada pengolahan pretreatment limbah POME di PKS Sei Pagar. Berdasarkan hasil seleksi, teknik pretreatment dengan karakteristik limbah POME yang memiliki biaya operasional relatif rendah yaitu teknik ultrasonik dan ozonasi.

Abstract

Biogas Power Plant (PLT) from palm oil mill effluent had been commissioned by a team from the Center of Technology for the Energy Resources and Chemical Industry, Agency for the Assessment and Application of Technology (PTSEIK-BPPT). The biogas power plant is located in PTPN V Kampar, Riau Province. A PLC (Programmable Logic Controller) has been implemented to support the operation of biogas power plant. Proper sensor selection has been done for each measurement applications. A computer and mimic panel is used as an interface for the operation of PLC. The master control system communicates with the slave control systems and Human Machine Interface (HMI) by means of ethernet communication protocol. Commissioning phase is carried out for 2 hours with a load of 450 kW. Instrumentation and control system is able to measure important variables such as fluctuation in methane numbers, pressures, and biogas flow rate to check the suitability of biogas supply in accordance to gas engine specification.

Abstract

Slow release fertilizer (SRF) of urea is prepared by using zeolite as the matrix. Mixing of urea and zeolite is carried out in orbiting screw mixer. The effects of rotation speed and orbital speed of the mixer and particle size on power consumption, homogeneity, mixing time and specific energy consumption are evaluated. The experimental results show that higher orbital speed gives higher power consumption. Power consumption is dominated by mixer rotation motion. Smaller particle size needs higher power for mixing process. Nitrogen mass fraction ranges from 0.45 to 0.49 when mixture reaches homogeneity. The mixing time required is about 5 – 12 minutes for particle size of >60 and >80 mesh and 7 – 14 minutes for particle size of >50 mesh. At constant orbit speed, the higher the screw rotation speed, the shorter time needed to reach mixture homogeneity. Specific energy consumption of mixing process increases with decreasing particle size. For the three particle size groups of >80 mesh, >60 mesh and >50 mesh, the lowest specific energy consumption is given by combination of orbital speed of 5 rpm and rotation speed of 50 rpm; while for particle size of >60 mesh and >80 mesh, it can obtained by combination of orbital speed of 5 rpm and rotation speed of 67,5 rpm and orbital speed 5 rpm and rotation speed 30 rpm, respectively. The lowest specific energy consumptions is gained by combination of orbital and rotation speeds of 5 and 50 rpm with particle size of >50 mesh.

Abstract

Palm oil mill effluent is a type of organic agro-industrial waste from the by-product of the processing of fresh oil palm fruit bunches to produce Crude Palm Oil. The management of POME as biogas is an added value for companies to meet the needs of energy sources in the Palm Oil Mill, both for Crude Palm Oil, Kernel Crushing Plant, and domestic needs as a source of electrical energy. POME is a colloidal suspension containing 95-96% water, 0.6-0.7% oil and 4-5% fat and total solids. Anaerobic degradation of POME is the main stage in the biogas production process at the Sei Pagar Palm Oil Factory. The ambient temperature was measured at 08.00, 13.00, and 18.00 for 11 days of testing. To analyze the effect of ambient temperature on sample temperature, a sample temperature test was carried out using a pH meter for each ambient temperature test. To analyze the impact of ambient temperature on the flow rate of gas produced and methane content in biogas, the sensor flow rate was checked with the valve at the reactor outlet fully open. The ambient temperature of the reactor does not change the sample temperature because the temperature in the reactor is controlled by the feed entering the reactor. The average temperature of the reactor environment is lower than the reactor so that it does not affect the gas flow rate (biogas formation process). The average temperature of the reactor environment is lower than the reactor temperature so that it does not affect the formation of methane.
