Abstract
The use of simulation and analysis in the unit operation has the objective of checking the operation of an equipment under specified conditions and perform a possible operation optimization using many different tools. One of the objectives is to get the specification data of naphtha stabilizer tower and resorting Aspen HYSYS commercial software. Applying this software it was possible to find the convergence of this process. The specified temperature of outlet stream in the heat exchanger was changed to have a possibility of getting the equipment convergence. Thus, the profile of the product streams was obtained for this operation, checking contamination of light chain by the presence of NBP 11, NBP 26, and NBP 40. Changing the temperature profile of the tower, could observed the decrease of contamination, which is already a desired result.
