Menez, Charles Samuel E. CHM031 HW08 – Petroleum Processing The processes involved in the petroleum refining Separation In the first step, molecules are separated through atmospheric distillation (i.e. at normal atmospheric pressure), according to their molecular weight. During the process, which is also known as topping (refining) , the oil is heated at the bottom of a 60-meter distillation column at a temperature of 350 to 400°C, causing it to vaporize. The vapors rise inside the column while the heaviest molecules, or residuals, remain at the bottom, without vaporizing. As the vapors rise, the molecules condense into liquids at different temperatures in the column. Only gases reach the top, where the temperature has dropped to 150°C. The liquids, which are become increasingly light the higher they are found in the column, are collected on trays located at different heights of the column. Each tray collects a different petroleum cut (fraction) , also known as a petroleum cut, with highly viscous preservation (hydrocarbons)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
