Reboiler sizing - Petrol Diesel split - help required 1

[v8landy]

Hi

I am looking for help sizing a reboiler for a new project.

70 million L per year of pertol /diesel mix.

Petrol over top, diesel as bottoms product. Not using a kettel.

I have column reseved on the used market, 52 trays bubble cap 1 m diam x 15.540 m tall.

I am thinking about introducing feed at a mid point, with pre heating via steam??? Size of pre heater???

Main reboiler will be via hot oil. We have 2 hot oil heaters 1 at 1.76 MW other at 0.76 MW

I would be looking for about 7 - 8 T per hour boil up

Thanks

What you need is someone to perform a distillation process design for you. I would suggest you locate a chemical engineer experienced in the use of one of the many available simulation programs and ask him/her to do it for you ... or pay to have him/her do it for you.

I might also add that he/she will want to have a detailed fractional distillation assay of your petrol-diesel mixture. Both petrol and diesel are generic terms and their physical properties (boiling range, etc.) may vary significantly from one source refinery to another.
