The accuracy of using linear models for crude distillation unit (CDU), fluidize-bed catalytic cracker (FCC) and product blending in refinery planning has been debated for decades. Inaccuracy caused by nonrigorous linear models may reduce the overall profitability or sacrifice product quality. On the other hand, using rigorous process models for refinery planning imposes unnecessary complication...

Renewable energy sources are generation alternatives that can be used for different applications; Systems take advantage of photovoltaic solar to reduce demand during daytime hours, electrification isolated homes, among other applications. In Ecuador there is a high potential radiation, which also applied project systems connected the electricity grid or in form distributed generation, objectiv...
