Empirical equations and economical study for blending biofuel with petroleum jet fuel.

Distillate of upgraded palm biodiesel was blended in different volume percentages (5, 10, 15, and 20%) with jet A-1. The mixture can be used as a replacement for petroleum Jet fuel. Physical properties of blends were measured and compared with those of jet A-1.

Treatment of hazardous wastewater contaminated by nitrocellulose.

Based on successful preliminary bench scale experimental studies for treatment of industrial wastewater contaminated by nitrocellulose, a pilot plant is constructed for results assessment. Bench scale experimental work proved 55%, 73% recovery of nitrocellulose without and with chemical addition respectively within 10 min flotation compared to 35%, 69% recovery within 2-0.5h settling respectively.
