Optimization can be defined as the use of the specific methods to determine the most effective and economical solution to a problem in a process. Optimization is one of the most important decisionmaking tools in the industry. Optimization uses the effective quantity methods by choosing the bestanswer or solution among the possible solutions. Of course, computers and the related software have made the necessary calculations feasible with the least cost. In this paper, an energy optimization has been done for condensations stabilization unit of Ilam gas refinery (IGTP). Atfirst, the stabilization unit has been simulated and examined in the environment of the commercial HYSYS Refinery software by taking into account all the details. Then, it has been defined by using integration techniques and scenario processing facilities with the purpose of losing Electricityconsumption. Again, the presented scenario was defined in the software. The obtained results from the simulation reveal that in case of using feed stream as the energy integration factor (for cooling)and using heat exchanger Instead of the present air conditioner, 1\1 Mega Watt electric power will be saved in addition to the omission air conditioner 1060\1360 AC (this equipment is currently being used for cooling) and the reduction of operating costs amounted to be more than $ 522,240 a year<\div>

Vanadium oxide nanotubes were synthesized using V2O5 powder as the precursor and hexadecylamine as the structure–directing template using a sol–gel reaction method followed by a one–step hydrothermal treatment. The structure and morphology of the nanotubes were investigated by X–ray diffraction, scanning electronmicroscopy, and transmission electron microscopy. The inner and outer diameters of the nano tubes varied from 30 to 40 nm and 50 to 130 nm, respectively. The nano tubes measured several micrometers in length<\div>

In order to separating benzene and toluene (BT), in the aromatic distillation unit of Bu Ali petrochemical are used of a distillation column containing 55 trays. For condensing steam in the upper part of air cooler and down, a natural gas furnace, which the fuel is sharply 1 million cubic foot (MMscfd) is applied. It was equipped with two ultra high energy consumption so that energy costs has been estimated 93384 $ in the year. in this study, According to the need of reduce energy consumption in consumer industries, especially oil, gas and petrochemical, we decided to investigate the energy recovery for aromatic distillation unit of Bu Ali petrochemical and with using of specialized software Aspen Plus we provided a method for this purpose. In this regard, According to information taken from Bu Ali complex, several simulations were performed, and finally, the least investments expensive model with reducing energy consumption has been selected. The results of the selected model can be cited to remove completely power consumption of the air conditioner, 45% reduction in fuel consumption in furnaces and heat exchangers, and ultimately 58% reduction in the production of pollutant emissions that play important role in damaging the environment<\div>

Drying process has various applications in industry. This process which is a thermal energy operation has various applications in drying food, wood, edible grains and various chemical and cellulosic materials. Consuming high amount of energy during in drying industry has turned this process to one of the high–energy–consuming operations, while it has a high industrial significance. In recent decades, thermodynamic analysis, especially exergy analysis, has turned to one of required tools in designing, analyzing and optimizing thermal systems. The following research tries to present drying process thermodynamic modeling, and especially fluid bed drying and simultaneous equations in mass and heat transfer. Also, it is tried to derive exergy returns in the form of a heat and mass transfer parameters function and its changes are studied based on inlet air heat, air specific exergy, exergy difference between input materials and output products, product weight, air humidity contents, and inlet\outlet air humidity ratio. This model could be advantageous in optimizing drying operation and determining proper application of each system, and optimized system shape and order.<\div>
