Rapid method for the separation of oil into fractions

[Category : - MECHANICAL ENGINEERING]
[Viewed 2423 times]

SVA is heat-and-mass transfering apparatus, in which the swift-flowing, non-equilibrium, the vacuum distillation process of a single evaporation of materials with its division into evacuated chamber on the total steam distillate and tar followed by a single total vapor condensation or fractionation step in a fixed sequence by during the vapor condensers. When required, the flash unit can be made multi-step.
In the vacuum chamber - SVA reactor oppositely arranged nozzle-dispensers for destructive (cavitation) treatment and spraying of raw materials in the form of finely dispersed torches. The chamber is equipped with thermal device to prevent the evaporation cooling of the torch of his low-boiling component of raw materials and / or providing an efficient thermal cracking of the oil in the droplet state. There are, moreover, a catalytic cracking feedstock stream prior to entering the vacuum chamber, and hydrocracking under excess pressure in the chamber itself in the form of a droplet. If necessary, more subtle than allow capacitors, fractionation distillate phase, SVA can be combined with distillation column. In this case, the column operated only in the distillate and consequently higher quality products emanating from it.
Thus, the conceptual advantage of the SVA is possible to combine in a single installation of the primary and secondary processing of raw materials, making the SVA is very versatile piece of equipment. SVA, depending on the raw materials and final products may be used for conventional mini completion refinery or, more generally, to replace them.
