Abstract

The growth of the oleochemical industry generated a large amount of spent bleaching earth (SBE) solid waste that causes environmental problems. The SBE solid waste produced is reported at about 600,000 metric tons per year. Recovery of the oil from SBE can be an alternative solution to reduce the negative impact of SBE solid waste. In this study, the recovery of oil from SBE was carried out by the reflux extraction method followed by a study on its properties. The oil recovery process was conducted by using two different solvents (acetonitrile and n-hexane) at different particle sizes (40, 60, 100 mesh) of SBE, solvent-SBE ratios (2:1, 3:1, 4:1), and extraction time (1, 2, 3 hours). Experimental results showed that n-hexane extracted oil with yield ranged from 5 to 14.8%, while acetonitrile extracted oil with yield ranged from 0.68 to 8.4%. Product analysis shows that the oil extracted has a water content of 1.56% and 2.53% for acetonitrile and n-hexane, respectively. The viscosity analysis results show that the oil viscosities were 5.83 cSt (acetonitrile) and 5.09 cSt (n-hexane) which is in reasonable agreement with the Indonesian National Standard for vegetable oil (SNI 7709:2019). The result suggested that n-hexane provided better product yield than acetonitrile as a solvent for oil recovery from SBE. This study provides an alternative method and solution for the oleochemical industry in managing SBE waste.
