Performance of Palm Oil Mill Effluent (POME) as Biodiesel Source Based on Different Ponds

The purpose of this paper is to prove that waste palm oil industry (POME) can be used as raw material (source of energy) for biodiesel. In the production process, palm oil mill produced large amounts of waste. The provision of a shelter pond system is a temporary solution from palm oil mill to relocate the liquid waste. With BOD content with range 25,625 to 39,616.7 mg/l and COD content with range 117,333.3 to 146,333.3 mg/l, this condition will generate a serious problem for environmental pollution. Therefore, it is important to test the characteristics of waste oil from each pond. The hexane solvent extraction method is used to separate the oil from the liquid waste. The first pond contains 51.3% water, 21% oil, 2% sludge & sediment and 5.6% free fatty acids. The second pond contains 86.7% water, 16.1% oil, 2.4% sludge & sediment and 8% free fatty acids. The third pond contains 74% water, 6.8% oil, 3.1% sludge & sediment and 12.2% free fatty acid and the fourth pond contains 78.7% water, 3.7% oil, 2% sludge & sediment and 13.3% free fatty acids. Based on the results of this research, the characteristics of POME and its oil losses are the fraction of oil wasted from Crude Palm Oil (CPO) processing, whereas CPO has characteristics as a raw material for Biodiesel. POME should be processed into biodiesel since the liquid waste is discarded from palm oil mill, so there is no need a big land to make waste storage ponds.

Although Palm Oil Mill Effluent (POME) can be used as a raw material for biodiesel production, the POME contains an excessive amount of Free Fatty Acids (FFA), necessitating a preliminary process and esterification. POME is degummed using phosphate acid and bleached with carbon active. Additionally, this study used KOH-impregnated zeolite to reduce FFA. The purpose of this study is to determine the effect of adding impregnated zeolite on esterification. POME was heated to 600C for 30 minutes, then degumming with 3 % of phosphate acid for 30 minutes, followed by bleaching with carbon active with a comparison ratio of 8:3 at 1000C for 1 hour, and finally, esterification with 3 percent impregnated zeolite from the POME weight at 600C for 4 hours. The analysis was conducted using titration methods to determine the FFA of each esterification. The data will be compared between zeolite and non-zeolite degumming, bleaching, and esterification. The results indicated that the most effective method for reducing FFA was degumming, bleaching, and esterification with zeolite.

This paper reports the minimum requirements of nickel and cobalt as trace metals in the formation of biogas from the digestion of palm oil mill effluent (POME). Anaerobic digestion was conducted in a two-liter continuous stirred tank reactor (CSTR) and operated at a thermophilic condition of 55oC. As raw material, a non-treated liquid waste from the mills was used. Hydraulic retention time (HRT) of the digesters was preserved at six days. The results come to the conclusion that the decrease of trace metals concentration didn’t influence the total solid, volatile solid concentration and also M-alkalinity. Based on the analyzed parameter, the reduction of trace metals concentration up to 97% of the initial nickel and cobalt concentration, 0.49 and 0.42 mg/L for nickel and cobalt, still allows the fermentation to obtain optimum biogas production, where the 90% reduction of trace metals produced the average volume of biogas 10.5 L/day at the rate of VS degradation 52-53%.

Palm oil mill boiler ash is one of the substances that can be used as an adsorbent. The adsorbent can absorb certain components of a fluid phase, which before being applied needs to be activated using chemicals so that the effectiveness of the absorption is increasing. The use of adsorbents in CPO is quite effective in maintaining its quality. Several previous studies have studied the application of adsorbents in maintaining the quality of CPO. The purpose of the study was to utilize palm oil mill boiler ash as an adsorbent of several types of activators and to determine the effect of effective activator types in application to the quality of CPO oil. This study used a non-factorial completely randomized design with adsorbent activation treatment using H3PO4 and NaCl with a concentration of 10% and soaked for 24 hours. There are 3 parameters observed in the adsorbent application to CPO, namely free fatty acids, water content, and dirt content. The results showed that the adsorbent activated with H3PO4 was an effective adsorbent with a decrease in its free fatty acids up to 0.43%, water content decreased to 0.07%, but an increase in CPO impurities content of 0.24%. While the adsorbent activated using NaCl showed free fatty acids 0.22%, water content decreased by 0.03% and dirt content also increased by 0.24%.

Selection Of

Crude palm oil (CPO)is the richest natural plant source of carotenoids in terms of retinol (pro-vitamin A) equivalent, whereas palm oil mill effluent (POME) is generated from palm oil industry that contains oil and carotenes that used to be treated before discharge. Carotenoids are importance in animals and humans for the purpose of the enhancement of immune response, conversion of vitamin A and scavenging of oxygen radicals. This component has different nutritional functions and benefits to humaan health. The growing interest in the other natural sources of beta-carotene and growing awareness to prevent pollution has stimulated the industrial use of CPO and POME as a raw material for carotenoids extraction. Various technologies of extraction and separation have been developed in order to recover of carotenoids.This article reports on various technologies that have been developed in order to recover of carotenoids from being destroyed in commercial refining of palm oil and effects of some various treatments on the extraction end separation for carotenoid from palm oil and carotenoids concentration. Principally, there are different technologies, and there is one some future which is the use of solvent. Solvent plays important role in the most technologiest, however the problem of solvents which are used is that they posses potentiaal fire health and environmental hazards. Hence selection of the most safe, environmentally friendly and cost effective solvent is important to design of alternative extraction methods.Chemical molecular product design is one of the methods that are becoming more popular nowadays for finding solvent with the desired properties prior to experimental testing.ABSTRAKMinyak sawit kasar merupakan sumber karotenoid terkaya yang berasal dari tanaman sawit sebagai senyawa yang sama dengan retinol atau pro-vitamin A; sedangkan limbah pengolahan minyak sawit dihasilkan dari industri pengolahan minyak sawit yang berisi minyak dan karotene yang perlu diberi perlakuan terlebih dahulu sebelum dibuang. Karotenoid merupakan bahan penting yang diperlukan pada hewan dan manusia guna memperkuat tanggapan terhadap kekebalan, konversi ke vitamin A dan penangkapan gugus oksigen radikal. Dengan berkembangnya ketertarikan dalam mencari beta-karotene yang bersumber dari alam lain dan meningkatnya kesadaran untuk mencegah adanya pencemaran lingkungan, maka mendorong suatu industri untuk menggunakan CPO dan POME sebagai bahan baku untuk diekstrak karotenoidnya. Berbagai macam teknologi guna mengekstrak dan memisahkan karotenoid telah dikembangkan untuk mendapatkan kembali karotenoidnya. Makalah ini melaporkan dan membahas berbagai jenis teknologi yang telah dikembangkan guna mendapatkan kembali senyawa karotenoid dari kerusakan di dalam proses pemurnian minyak sawit secara komersial dan pengaruh beberapa perlakuan terhadap ekstrasi dan pemisahan karotenoid dari minyak sawit dan konsentrasi karotenoidnya. Pada prinsipnya, berbagai teknologi yang digunakan untuk mengekstrak dan memisahkan karotenoid terdapat perbedaan, dan terdapat salah satu teknologi yang digunakan untuk esktrasi dan pemisahan karotenoid adalah menggunakan bahan pelarut. Pelarut yang digunakan mempunyai peranan yang penting dalam teknologi ekstrasi; namun pelarut yang digunakan untuk mengekstrak tersebut mempunyai persoalan karena berpotensi mengganggu kesehatan dan membahayakan cemaran lingkungan. Oleh karena itu, pemilihan jenis teknologi yang aman, ramah terhadap lingkungan dan biaya yang efektif untuk penggunaan pelarut merupakan hal penting sebelum dilakukan desain metode/teknologi alternatif untuk esktrasi karotenoid. Pola produk molekuler kimia merupakan salah satu metode yang saat ini menjadi lebih populer untuk mencari pelarut dengan sifat-sifat yang dikehendaki sebelum diujicobakan.

Palm Oil Mill

Palm oil mill effluent (POME), a pollutant produced by the palm oil industry, was treated by the Vetiver system technology (VST). This technology was applied for the first time to treat POME in order to decrease biochemical oxygen demand (BOD) and chemical oxygen demand (COD). In this study, two different concentrations of POME (low and high) were treated with Vetiver plants for 2 weeks. The results showed that Vetiver was able to reduce the BOD up to 90% in low concentration POME and 60% in high concentration POME, while control sets (without plant) only was able to reduce 15% of BOD. The COD reduction was 94% in low concentration POME and 39% in high concentration POME, while control just shows reduction of 12%. Morphologically, maximum root and shoot lengths were 70 cm, the number of tillers and leaves was 344 and 86, and biomass production was 4.1 kg m−2. These results showed that VST was effective in reducing BOD and COD in POME. The treatment in low concentration was superior to the high concentration. Furthermore, biomass of plant can be considered as a promising raw material for biofuel production while high amount of biomass was generated in low concentration of POME.

Land application of liquid waste containing palm oil mill effluent (LW-POME) as soil ameliorant can cause water contamination due to its high content of nitrate if improperly treated. Indonesia is rich with volcanic tuff materials that contain variable charged soil clay minerals. This study was aimed at to extract nanoclays (fraction sized <200 nm) from volcanic tuffs of Mt. Salak, West Java, Indonesia, and evaluate their potential use as adsorbent of nitrate in LW-POME. By applying dispersion, ultrasonication, centrifugation, and dialysis separation techniques, it could be extracted positively charged nanoclays nc3 and nc4 from the respectively tuff materials tv3 and tv4. Their potential use as natural adsorbent of nitrate as anionic contaminant was evaluated using Langmuir isothermal adsorption model. After 48 h equilibration, it could be extracted 4.33 mg nc3/g tv3 and 7.73 mg nc4/g tv4 with nitrate adsorption maxima of 48.3 and 40 mg/g for nc3 and nc4, respectively. The removal of nitrate in the LW-POME from 62 to 20 mg/L as to comply with the Indonesian liquid waste quality standard required 29.81 mg nc3/L or 39.34 mg nc4/L. The extracted nanoclays were considered prospective to be utilized as natural adsorbent for nitrate removal in LW-POME.
