UNIT’S OPERATION PRINCIPLE
PREPARING A MIXTURE OF NANOCATALIZER WITH RAW MATERIAL
The fuel oil residue, heated up to 60 °C is supplied by the pump to the mixer to be mixed with nanocatalizer in the amount of not more than 2% of the mass of raw material.
AFTER HEATING UP TO 138 °C IN THE INTERPIPE SPACE OF THE HEAT EXCHANGER, THE MIXTURE GOES TO THE PIPE OF THE HEAT EXCHANGER TO BE HEATED UP TO 320 °C AND THEN GOES TO THE REACTOR OVEN FOR CRACKING AT THE TEMPERATURE OF 385-440 °C UNDER PRESSURE OF 0.6-0.7 mpa (6-7 kgs/cm2).
CRACKING RESIDUE SEPARATION
From the reactor oven, nanocatalytic cracking product goes into the separator where the liquid cracking residue is separated from the vapour-gas catalyst. The catalyst comes into the interpipe space of the heat exchanger to be cooled to the temperature of 200-220 °C, at the same time heating the mixture of residue with nanocatalizer coming to the heat exchanger.
Cracking residue separated from gaseous catalysts comes to the tube space of the heat exchanger to be cooled to 140-150 °C, providing primary heating of the mixture of nanocatalizer and residue to be then taken to the warehouse.
SECTION OF LIQUID CATALYST
Cooled down to 40 °C the catalyst as a gas-liquid goes to a separator where the liquid catalyst is separated from hydrocarbon gases. Liquid catalyst is pumped out for further processing.
Hydrocarbon gases are being separated by the compressor and go to the refrigerator-condenser for cooling.
SECTION OF DRY HYDROCARBON GASES
Cooled down to 30 °C hydrocarbon gases go to the separator, where separation of dry and fat gases is conducted. Fat gases are to be separated to the storage container of liquefied gases, and non-condensed dry gases are separated to the fuel network.
