This method was refined base oil, which can be split into parts. This process is the basis of the characteristics of different parts of the crude oil with a boiling point temperature different from the first.As a result, the first step is the condensation of the crude oil. Different from the crude oil. Tank will be pumped into the furnace.The oil is then passed into the distillation sequence. Shaped as a cylinder with a height of about 30 meters and a diameter of approximately 2.5-8 meters inside the distillation column is divided into several different rooms in a horizontal position. The baffle tray that looks like a round room by room, all the baffles have holes in them. So the steam can penetrate into the hot oil.The hose for the oil condensation away from the distillation of crude oil, when hot steam is sent to a distillation column into the pipeline. I will be moving up to the top of the tower. As I moved up the oil cools.To condense at the bottom of the tower, which has a high temperature and can be drained away from the base of the tower and the disadvantages of distillation sequences. The oil is light in very small proportion of all types of light oil.
