With the increasing awareness of environmental protection, countries around the world have implemented new regulations that strictly limit the sulfur content in fuel oil. Diesel Desulfurization Machine can bring the sulfur content down to 10ppm or lower, completely remove nitrogen from the oil, and deeply decolorize the oil,and output diesel fuel can be directly used for vehicles. To this end, YANGJIANG developed YJ-SNC Diesel Desulfurization Machine and YJ-SNC Black Diesel Desulfurization Plant.
