SUPERLIGHT FUEL OIL, THE METHOD OF ITS PRODUCTION AND THE DEVICE FOR THE METHOD REALIZATION Russian patent published in 2006 - IPC C10L1/04 C10L1/32 B01F3/10 B01F13/10 

FIELD: petrochemical industry; methods and devices of the superlight fuel oil production.

SUBSTANCE: the invention is pertaining to the field of petrochemical industry, in particular, to the method and the device for production of the superlight fuel oil. The superlight fuel oil is used as the technological fuel at the industrial enterprises, at heat supply enterprises, and also by the sea and river fleet ships. The superlight fuel oil contains 25-50% of the stabilized gaseous condensate with the contents in it of the fractions C₁-C₄ in the amount of no more than 0.3-1.0 % and the rest is the fuel oil of the furnace brand М100 and-or М40. The method of production of the fuel oil provides for mixing of the heated up to 50°C fuel oil of the furnace brand Ml00 and-or М40 with the stabilized gaseous condensate with the temperature of 20°C under pressure up to 3 atm in the given ratio in the chamber of the components mixing. Then the produced mixture is fed into the emulsification device, where it is subjected to the ultrasonic treatment for production from the fuel oil mixture of the finely dispersed emulsion. The subsequent remixing of two and more streams of the finely dispersed emulsion of the fuel oil mixture with the permanently maintained temperature pf 50-60°C is conducted in the chamber of the intensive mixing due to organization of intermixing by the counter currents under pressure and transportation of the target product into the containers of the accumulators integrated by the system of circulation, subjecting the end product to the constant circulation under the pressure of up to 2 atm and to passing through the emulsification device. The invention also presents the installation of production of the superlight fuel oil, which contains the components supply systems and the mixing chamber. The supply system of the gaseous condensate and the supply system of the fuel oil each contains: the pump; the leak valve and the consumption indicator for the components feeding into the mixing chamber; the ultrasonic emulsification device; the chamber of intensive mixing with the preheating; the accumulator consisting of the container, the leak valve of an end product with the consumption indicator and the leak valve of the feeding of the superlight fuel oil to the customer. The system is integrated with the circulating system. The circulating system includes additional container, the pump, the leak valve, the consumption indicator. The technical result of the invention is the increase of the flowability and the service life of the produced product, improvement of the ecological indexes of the fuel oil per a unit of the heat capacity due to application of the simple production equipment and the optimal composition of the fuel oil.

EFFECT: the invention ensures the increased flowability and the service life of the produced fuel oil product, improvement of ecological indexes of the fuel oil per a unit of the heat capacity.
