描述:
Thermal vacuum plants TVK and Oxidation plants TOK for the production of tar and bitumen (road and construction). The installation of vacuum distillation of fuel oil allows you to increase the yield of a product with a large added value (vacuum gas oil). And also, due to the increased temperature, the process of partial thermal cracking takes place in the furnace. Which also increases the yield of light fractions. Especially if before entering the furnace, fuel oil passes through a hydrodynamic unit (HDU), the yield of gooil fractions will increase by another 5-10%.
概观:

Description of the operation of the installation: fuel oil, pump NMSh, equipped with a frequency converter, supplies a uniform amount of fuel oil to the furnace through the heat exchangers. Preheating with the secondary heat of waste products (which increases the efficiency of the furnace and reduces the cost of fuel oil). The furnace is equipped with a heat recuperator, which makes it possible to recover the heat from the flue gases of the burner. After heating to a predetermined temperature in the furnace, the fuel oil enters the vacuum column. In the column, due to the temperature and the creation of a vacuum created by a vacuum pump, the fuel oil evaporates (at a temperature of 360 ° C, with a vacuum, the oil evaporates as it would evaporate at a temperature of 530 ° C). After the vacuum column, the vacuum gas oil, being cooled to a predetermined temperature, enters the separation column. Where gas oil is divided into heavy vacuum gas oil and light gas oil. Heavy gas oil, after passing through the coolers, is pumped into the tank. Light gas oil, after the coolers, enters the gas separator, where from the top of the separator, uncondensed gas is pumped out by vacuum pumps, thereby creating a vacuum in the entire system. And from below, by a pump, light gas oil is fed into the tank. The tar from the bottom of the vacuum column, having passed through the heat exchangers and coolers, is pumped into the tank by pumps. The NMSh pump, equipped with a frequency converter, supplies a uniformly specified amount of tar to the furnace through heat exchangers, preheating with the secondary heat of waste products (which increases the efficiency of the furnace and reduces the cost of fuel oil). The furnace is equipped with a heat recuperator, which makes it possible to recover the heat from the flue gases of the burner. After heating to a predetermined temperature in the furnace, the tar enters the oxidizing column. In the column, due to the dosed supply of air by compressors, at a given temperature and pressure, the tar is oxidized, turning into bitumen. To prevent the column from igniting, since it contains atmospheric oxygen, water vapor is supplied to the top of the column from the steam generator. After passing the oxidation reaction of the tar to bitumen, it, through heat exchangers, enters the tank. From the top of the column, a light reaction product (black solarium) leaves and, after cooling in a cooler, enters the tank.
The equipment works according to the traditional principle, it does not contain revolutionary solutions that have not been tested by time. The world's best heat-resistant heat-insulating brick based on vermiculite is used in the furnace, which eliminates heat loss. Therefore, the furnace has the best efficiency in the industry. Also, the furnace uses one of the most advanced block burners in the world made in South Korea. These burners have a simple design. Efficiency compared to Russian counterparts is 30% higher. Excellent stability in work and availability of spare parts. The advanced principle of operation of furnaces was applied (the flame of the burner does not just pass through the furnace furnace, as in most designs, but reaches the back wall, cuts through the outer side of the coil block, once again giving off heat to heat the raw material, enters the heat recuperator through the chimney, where the raw material is preheated by the exhaust gases, which contributes to the complete removal of heat from this plant).
The unit provides for a heat recovery system using heat exchangers, which saves both electricity and fuel for the burners. The resulting product is air-cooled by highly efficient coolers-condensers of our own design, which have proven their high performance properties.
