(some col.) ; 30 cm. + 1 CD ROM Faculty of Chemical & Natural Resources Engineering Project Paper (Bachelors of Chemical Engineering) -- Universiti Malaysia Pahang – 2015 Bibliography : p. 50-53 Palm pressed fiber (PPF) is the solid waste produced from palm oil milling company after the pressing process. Recovery of oil and reuse of the palm pressed fiber is a great opportunity for cost saving in the oil processing industry. The objective of the research is to recover residual oil which still left in the PPF by using ultrasonic-assisted extraction method (UAE). The process is carried out by priory drying process of the PPF at 60 °C for 1 hour. Then the dried sample will undergo the extraction process in the ultrasonic bath by using methanol as a solvent. The effect of solid: liquid ratio and extraction time are varies in the range of (1:3-1:8) and (0 minutes-60 minutes) respectively. Yield of the extracted oil are measured for all conditions. Results from studies shows that the highest yield is 12.90% which obtained at the condition 1:5 (g/ml) of the solid: liquid ratio and 30 minutes of the extraction time. Hence, the result from Gas chromatography-mass spectrometry (GC-MS) has confirmed that the properties of the extracted oil are almost similar to the crude palm oil (CPO) Faculty of Chemical & Natural Resources Engineering Dissertations Universities and Colleges Dissertations Theses http://ecollib.ump.edu.my/id/eprint/25592 Access in library only http://ecollib.ump.edu.my/25592/ Access in library only 0 0 0 1 10000 10000 2019-09-04 0 FKKSA .A99 2015 r Bc. 0000107599 2019-09-04 00:00:00 1 2019-09-04 PSM 0 0 0 1 10000 10000 2019-09-04 0 CD 9561 | FKKSA .A99 2015 r Bc. 0000107600 2019-09-04 00:00:00 1 2019-09-04 PSM VIRTUA40 6586 6592 VTLSSORT0080*0200*0400*0900*1000*2450*2600*3000*5000*5020*5040*5200*6100*6500*6501*8560*8561*9992
