The Production of Non-separate Glycerin Blended Diesel from Waste Oil for Hydro Pump Engine

Abstract

The purposes of research aim to produce of non-separate glycerin blended diesel from used waste oil for hydro pump engine by processed for increase quality of used waste oil was moisture less by boiled and blended with petroleum oil then passed through the filter by non-separate glycerin blended diesel to ensure the primarily quality by visual inspection, hydrometer and litmus paper test. That was found that the blended diesel had a similar value. The blended diesel ratio 100/10 had 0.885 of specific gravity and pH 6.2. Blended diesel ratio 100/20 had 0.890 of specific gravity and pH 6.2 and blended diesel ratio 100/30 had 0.880 of specific gravity and pH 6.2. Then experiment of blended diesel with short-term engine to find the performance and break-even point in economics. The result of this research was blended diesel ratio 100/10 can be run short-term engine for 3.36 minutes and cost reduced 6.52 baht per liter. Blended diesel ratio 100/20 can be run short-term engine for 3.33 minutes and cost reduced 6.00 baht per liter. Blended diesel ratio 100/30 can run short-term engine for 3.23 minutes and cost reduced 5.50 baht per liter. Consequently the best average time of short-term engine run-test 3.36 minutes of blended diesel ratio 100/10 and breakeven point at 292.94 liters.
