heal.abstract
The main aim of this thesis is to perform a feasibility study of hydrogen production from hydrogen sulfide in Black Sea. The whole procedure consists of five major steps: • Pumping sea water from Black Sea • Extraction of hydrogen sulfide from sea water • Production of hydrogen and sulfur from H2O/H2S concentrations. • Utilization of H2 towards power production in fuel cell system. • Utilization of side products such as H2SO4 in an integrated and economic manner The application of this process would have a positive impact on both environmental and economic development of the Black Sea countries. The utilization of a rather toxic pollutant like H2S in order to produce hydrogen would diversify the power production sources and create eventually new job vacancies. The possible implementation of the proposed method would be really beneficial for vulnerable areas such as rural areas and isolated villages by providing electricity. From each step, several alternative approaches have been examined, and the optimum choice has been selected for further investigation. ASPEN plus software has been employed to elaborate all mass and energy balances. A sensitivity analysis of the critical parameters, such as fuel cell’s capacity that mostly affected the whole process by employing MATLAB software has been developed. For the base case, a techno economic analysis carried out including the description of all the necessary process equipment as well as the calculation of various economic criteria and indicators (NPV, IRR, and payback period). The assessment of the project leads to the conclusion that it is sustainable and rather profitable with:  NPV = 2,512,981 €  IRR = 23%  Payback period = 5.5 years
