    Simulation of process units in order to optimize them has long been considered in the chemical industry. Limited sources of energy supply and their increasing consumption in various industries have made optimization and subsequent energy integration important. There are many alternatives to designing a new process or optimizing an existing one, all of which can waste a lot of time and energy and increase costs. But with simulation software, the speed of estimating alternatives has increased. On the other hand, the optimization features in this type of software have caused the comparison of different processes to be done in the best possible way. Because the comparison of different alternatives should be compared and selected in optimal conditions. Aspen Plus software has process optimization features that the user can easily optimize the simulated unit by defining the objective function and existing constraints as well as free optimization variables. The user must first extract the variables contained in the objective and constraint function from flow Sheet 1 and define the objective function and constraints by combining these variables. Also, free optimization variables should be introduced from the available variables selected for optimization. In this project, optimization is done in order to produce 6 MW power.

  • Investigating the Impact of Energy on Iran's National Security
    Pedram Shirzadi *, Peyman Vaziri, Kim Lo Han, Andi Johnson Pages 161-167
    International relations experts acknowledge that one of the fundamental indicators of a hegemonic power in any age is the control of energy resources, lines, and routes. This fact has turned energy today into both a tool of power and a goal of power. Statistics on world oil reserves show that currently 62% of the World's proven oil reserves are concentrated in the Persian Gulf region. According to the US Energy Information Administration, global oil consumption will increase by 50 percent over the next two decades, from 85 million barrels per day in 2005 to 118 million barrels per day in 2025. Major oil market players are pushing for a national energy policy to secure their national interests. Influential countries in the global oil arena have found that as the concept of energy security becomes more complex and evolving, energy security and national interests are realized, requires the design and implementation of a "comprehensive national energy policy" that can address all specific dimensions of energy, technology, finance, and investment, environmental, political, security, and even cultural and social related to the field of energy within a program inside and outside the country. The pervasive, which has short and long-term dimensions and solutions, also came around.

  • Investigating the Effects of Government Oil Policies on the Iranian Economy
    Kim Lo Han, Pedram Shirzadi *, Peyman Vaziri, Andi Johnson Pages 168-173
    With the knowledge of oil and its various applications in the social, industrial, and economic fields, the land of Iran found a special situation and experienced significant changes. Oil has been influential in how the people and the government communicate in Iran over the last hundred years. For a variety of reasons, mainly related to policy-making, Iran's economy produces small products in the industrial and agricultural sectors and exports them to the outside world, and relies heavily on crude oil exports to meet its import needs. More than 80% of the country's foreign exchange resources and more than 70% of the general budget resources are provided by the oil sector. Thus, oil as a supplier of material resources and political structures and stimulating socio-political incentives in creating socio-cultural changes and the composition of wealth and income, despite its ups and downs, has played an effective and key role, and without a doubt, oil in the future will be able to create structural changes in various economic, social and cultural dimensions in Iranian society.

  • Investigating the Possibility of Modifying Water Management Engineering
    Peyman Vaziri, Pedram Shirzadi *, Kim Lo Han, Andi Johnson Pages 174-181
    Due to the pivotal position of water in the development of the country, the government is obliged to develop and reform the structure of water consumption and establish a proper exploitation system and by using modern irrigation and low irrigation methods, irrigation efficiency will result in water efficiency per cubic meter during the program. On the other hand, the law of equitable distribution of water for modern irrigation methods emphasizes that it is appropriate with the conditions of water extraction from groundwater despite the negative level of rainfall in many parts of the country; the Ministry of Jihad Agriculture should also make serious efforts in this regard. The point that is of great importance in the management of water resources and their consumption is to pay attention to the issue of drought; the crisis that our country has been grappling with for several years and exists in many parts of the country. Paying attention to global models for overcoming this crisis, planning for drought, and compensating for the damage caused by it can be a good help in this regard. Sustainable water management is an issue that the World Bank has put at the top of its agenda in the field of natural resource management.

  • Modeling of Calcium Carbonate Drying Process
    Amin Ahmadpour * Pages 182-188
    Calcium carbonate is one of the most essential minerals with multiple applications in diverse food, pharmaceutical, chemical, plastic, and paper industries that is generated by the press, mangle, deposition, and classification. In the simulation process mentioned in this research study, a mathematical model was provided to obtain dryer yield information. According to different methods of preparation and purification of this material, spray dryers are at the end of the process as dry goods market or required properties. For this reason, the first Kinetic of the material drying obtained through the experiment and the momentum equations of suspended particles in the air, particle path differential equations in three dimensions, Reynolds number, heat, and mass transfer coefficients and then calculate the mass and energy balance for presenting a mathematical model has combined, for discover the accuracy of the model, the results compared with practical experiments. A concurrent spray dryer used in the laboratory and a computer programming language (MATLAB) were presented to compare the results of its execution with the experimental results to assess the software’s accuracy.

  • Investigation of Photocatalytic Degradation Process in Wastewater Treatment Industry
    Amin Ahmadpour * Pages 189-202
    The process of photocatalytic degradation has emerged as a promising technology for the removal of pollutants from the air and is one of the most important and growing technologies in the field of wastewater treatment. This process in the operating conditions of ambient temperature and pressure has the ability to remove several types of pollutants in aqueous and gaseous environments and in this regard is relatively superior to other methods. Some of the other advantages of this new technology are: Unlike conventional treatment methods that transfer pollutants from one environment to another. The photocatalytic method usually leads to the production of harmless products. In this process, the usual methods and effluent flows should be used, which is not possible by other treatment methods. In this process, the reaction conditions are balanced and gentle, the reaction time is relatively short and the minimum additive chemicals are required. It is possible to combine this method with other treatment methods, especially biological treatment. Since the goal of photocatalytic reactions is generally the oxidation of organic matter and the reduction of inorganic matter, the main applications studied for this process are: decolorization and removal of pigment, reduction of effluent COD, complete removal of hazardous organic matter, elimination of material Hazardous inorganics such as cyanides, heavy metal treatment, fungicide decomposition, herbicides, harmful pesticides, purification and sanitation of water, elimination of foul-smelling compounds, removal of soil contaminants, removal of air pollutants, and elimination of cancer cells and viruses.
