GUERRA, S.G.; VAZQUEZ-ROMAN, R.  and  RODRIGUEZ-TORAL, M.A.. Simulation of Combined Cycle Cogeneration Plants using ASPEN®. Inf. tecnol. [online]. 2005, vol.16, n.1, pp.42-49. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642005000100007.

The objective of this work was to generate a strategy for combined cycle cogeneration plant design based on the ASPEN® process simulator. The approach included process simulation as well as definition of all key variables. Satisfaction of real vapor and electricity demands in a refinery was considered as a case study, using a scheme of combined cycle cogeneration. Considered in the model were the outstanding aspects of the state of the art for this technology, such as the calculation of the dew acid point to restrict the temperature of exhaust gases. Three schemes were analyzed to determine the best option for the case under study. It was concluded that this approach could be extended to other cases and could be applied to the future design of cogeneration plants in Mexico.
