EXTRACTION AND CHARACTERISATION OF SENNA–TORA (“TAFASA”) SEED OIL FOR ENGINEERING APPLICATIONS
Publication Date : 01/08/2010
Oil was extracted from Senna Tora (“Tafasa”) seeds and laboratory analyses were conducted to determine lubrication, cooling, and fuel properties of the oil. Results obtained were compared with PI and ASTM standard limits. The results showed that the oil had specific gravity of 1.153 kg/L at 300C, Kinematic viscosity of 22.20 Cst at 1000C, pour point of -50C, thermal conductivity of 0.381w/mk at 320C, specific heat capacity of 4.1J/kgK, ash content of 1.07% and moisture content of 12.27%. These properties were found to have satisfied both the PI and ASTM standard limits for lubrication and cutting fluid applications, but was however not suitable as fuel due to the absence of combustible fuel properties. The oil was therefore found to be suitable for lubrication and cutting fluid applications.
