Utilizing LPG as an Additive to Enhance the Properties of Iraqi Diesel Oil

Abstract

For environmental and economic purposes, it is necessary to search for methods that reduce gas emission by flare from the oil refineries. It causes environmental pollution and warmup. All laboratory tests have been completed at Koya University, with the contribution of the Institute of Technology in Koya, to check some readings and verify their accuracy. Increasing the absorptivity of the gases by heavy oil will have expected to improve oil burning characteristics. This research aims to determine the best operating conditions that leads for higher absorption. In this research the diesel oil is considered as a heavy cut and LPG as a light gas. A lab scale unit was installed for that purpose. The amount of changes in oil weight before and after atomizing was determines as well as, the properties of the diesel oil like flash point, cetane number, and diesel index. The effect of a wide range of atomizing time (10, 20, 30, 40, 50, 60, and 90) minutes at different temperatures (0, 10, 20, 30, 40, and 50) °C was considered. The data is discussed and graphically analyzed.  The optimum operating conditions is achieved by, 9 liters/minute gas Atomizing flowrate of LPG for one liter of diesel oil, atomizing Temperature is 30 ᵒC, atomizing Time is 30 minutes’ minimum till 60 minutes’ maximum. The produced Diesel Flash Point is 55 ᵒC, and the amount of gas absorption is 24 gm per 850 gm of diesel oil which represent 2.8 % of diesel weight and 5% of LPG gas flowrate.
