| dc.description.abstract | This project is concerned Comparative study of hydrogen production technologies, with the production assumed capacity of plant is about 500 kg/day of hydrogen gas .Due to the importance of hydrogen gas, there is a need for significant comparison between the production processes to select the optimum process. Therefore this project offers an overview of the most two important technologies for hydrogen production. These technologies which to be discussed are: Reforming of Natural Gas, and Water Electrolysis Decomposition, with the same assumed daily production capacity of hydrogen gas which is (500 Kg/Day). The first one steam methane reforming process that is called SMR, and the second one is the water electrolysis. This comparison Studies the differences between these two technologies , by doing the calculation which is the material balance ,that includes: the differences such as flow charts , the type and the quantities of raw materials are to be used, or the reactants and the amounts of materials products. The second step is the energy balance, this is important point that is determination the amounts of the energies for all streams in the processes. It has been considered that the optimum one is the process with low consumed energy. Moreover the most important comparison that includes, studying the economically side after design, by Selection the low capital costs .from the results the amount of the cost for these processes SMR ,and electrolysis water receptively are (816288.3$ cost, 13875968$ cost ). Therefore, it can be said that the appropriate production process must be with (high purity of hydrogen ,the low total cost, and the low energy consumed from this process ,even though with the rough operating conditions such as high temperatures and pressure). | en_US |
