When I was a child, I was walking with my father in his industrial work while he was doing his duty as an operator, I saw multiple big shiny towers ahead of us produsing loud noises, I said “ Father , what is that? is that a candy factory?!” asking my father, my father responded with a big laugh “No son, it is crude oil distillation unit!”. then years after years, I was always asking my father about the name of each individual unit and tower, then I went deeply through asking my father the functions of these unit, and its final product, recieving and absorbing knowledge from him, I fell in love with Chemical Engineering during my childhood.
