Abstract:
This study became to examine the possibility of benefiting from used oil by using it as fuel in some industries that require the burning of fuel for thermal energy conversion to any of the existing form of the various forms of energy, especially in the Sudan that has increased in the rate of the cars numbers in this period, which is an indicator of the large quantities of used oils , In this study, Three samples of used oils were taken, namely ( Turbine oil, transformer oil and engine oil ) by focusing more in the engine oil because of the abundance of this type there are a number of (536,745 cars in the Khartoum state as in the statistic of the traffic administration until 2007 , also the average quantity of lubrication oil used in the Sudan from 2006 until 2008 is 42,672 Ton. The samples of used oil were analyses to determine their properties as a fuel results showed good indicators of this species to be used as fuel, the heat content of these oils are reach a very large amount (45,352 kj/ kg) also during the analysis the presence of sulfur and ash content resulting from the combustion process found was verylow.
These types were tested through the combustion test and thus the analysis of combustion gases from the combustion process to determine the impact of pollution on the environment and human health, and the results are in the range permitted by the World Bank for the sulfur dioxide and Nitrogen oxides. The study concluded that the used oils can be used as fuel in many industries to take advantage of the thermal energy inside it.
The study has also concerned about a new product of the fuel produced in Sudan from Khartoum Refinery Company (K.R.C), by analyzed and tested it, economic and technical feasibility as a major alternative to the heavy fuel Sudanese oil which is produced from Elubaid refinery, used in Dr. Mahmud Sheriff thermal power station as a fuel for the boilers in phase I.
