Recovery of Base Oil from Waste Sludge Using Ultrasonic Solvent Extraction Method

Nowadays, waste sludge is commonly treated using biological, chemical and physical processes such as land farming, land filling, and incineration. However, those methods consume a lot of time, energy and operating cost. Thus, this work targets to recover the base oil from waste sludge using ultrason...

However, those methods consume a lot of time, energy and operating cost. Thus, this work targets to recover the base oil from waste sludge using ultrasonic solvent extraction method. It was done by determining the effect of ultrasonic power, extraction time and types of solvent used into the samples. The treatment of waste sludge using Hexane, Isopropyl alcohol (IPA) and Potassium hydroxide (KOH) as a medium solvent was conducted using ultrasonic bath (maximum power is 240W) at a different number of power scales, 0, 2, 4, 6, 8 and 9. The effects of treatment duration have been tested at different times which are 15, 30, 45, 60, 75 and 90 minutes. The types of solvent have been analyzed between the effect of Sodium chloride (NaCl) and Potassium hydroxide (KOH). The samples were then separated using a centrifuge machines in order to remove sludge particles at the bottom of centrifuges tubes. Based on the results obtained, it can be determined the optimum base oil recovery from waste sludge at 30 minutes with ultrasonic power at 53.3W which is on the power scale number 2 using KOH as a medium reagent. A characterization of waste sludge and recovered based oil such as viscosity, density, moisture content, flash point and ash content have been done using American Society for Testing and Material (ASTM) method. From the results, it can be conclude that ultrasonic treatment has been proved as an effective treatment of waste sludge and able to get high yield which was 65% of base oil recovery compared to the conventional treatment only achieved 30% which can save disposal cost, produce new valuable product of base oil as a raw material of lubricant oil and at the same time protect the environment. 2015 Conference or Workshop Item PeerReviewed application/pdf en http://umpir.ump.edu.my/id/eprint/13994/1/Recovery%20of%20Base%20Oil%20from%20Waste%20Sludge%20Using%20Ultrasonic%20Solvent%20Extraction%20Method.pdf application/pdf en http://umpir.ump.edu.my/id/eprint/13994/7/fkksa-2016-najib-Recovery%20of%20Base%20Oil%20from%20Waste%20Sludge.pdf Mohd Najib, Razali and Mohammad Hafizuddin, Hambali and R.
