crude oil unit simulation
(OP)
Hello for every one .. When I need to do simulation of crude distillation unit by aspen hysys or aspen plus or any other simulator, which data i should use in the assay of the crude oil : the true boiling point data or simulated distilation data.
Thanks for All....

TBP curve is a continuous curve, so it is possible to have tabular data expressed for each % distilled (if one wishes to). See below. You could assign the value of temperature for each % of distilled sample. The more values you enter in TBP characterization table, the more accurate simulation will be.
Cuts are cumulative yields of products estimated from TBP curve, however different in reality due to non-ideal separation in atmospheric crude towers. This non-ideality is usually expressed by 5% D86 temperature of heavier product minus 95% D86 temperature of the adjacent lighter product. You can read more in Watkins' and Jones' books, some info also in the link below.

After entering TBP data, define the cuts in the simulator in the same way they are defined in the first table (i.e. IBP-70, 70-140, 140-190, etc.), and see how good predictions you get (compare cumulative yields from the simulator vs. yield from the first table above).
