Hello students, in this question we have to explain the role of the label parts in the flow diagram.
00:06
The first part given here is the furnace.
00:09
So, furnace is where the feedstock is heated to the high temperature.
00:16
Therefore, the hydrocarbon here will break down into the smaller molecule.
00:23
The second one is the quench column.
00:25
So, the quench column in which the broke down particles that is the product that is obtained from the furnace will cool down to the lower temperature in the quench column.
00:40
And the third part is the compression system.
00:42
In the third part, the cool product from the quench column is compressed, is compressed so that the pressure of the product increases.
00:56
The fourth part is the caustic scrubber.
00:59
In the fourth part, the compressed product is treated with the caustic that is the caustic soda in order to remove the impurities from it.
01:13
And the fifth part is the drying unit.
01:17
In the fifth part, this purified product obtained from the caustic scrubber is dried, dried.
01:26
And the sixth part is the cold box.
01:29
The cold box where the product obtained from the previous stage is cooled and separated into different components...
