Shree Hari Group of Companies supplies Lube Oil Extracted from Crude Oil. Shree Hari Group of Companies supplies ferrous and non - ferrous metal scraps, petro chemicals, cement and cement clinker, coal and paper scrap. Lube Oil Extracted from Crude Oil undergoes a preliminary purification process [sedimentation] before it is pumped into fractionating towers. Lube Oil Extracted from Crude Oil has been manufactured by a typical high-efficiency fractionating xtower, 25 to 35 feet [7.6 to 10.6 meters] in diameter and up to 400 feet [122 meters] tall which is constructed of high grade steels to resist the corrosive compounds present in crude oils; inside, it is fitted with an ascending series of condensate collecting trays. Within a tower, the thousands of hydrocarbons in crude oil are separated from each other by a process called fractional distillation. As the vapors rise up through the tower, the various fractions cool, condense, and the oil return to liquid form at different rates determined by their respective boiling points [the lower the boiling point of the fraction, the higher it rises before condensing].
