Keywords: | heavy fuel oil gasification power generation desulfurization synthesis gas sulphur absorption gas engines |
Abstract (eng): | Gasification is a technologically advanced, environmentally friendly and proven technology for disposing high sulphur heavy fuel oils by converting them into clean combustible gas products, avoiding corrosion problems and environmental emissions. Due to the high sulphur content of heavy fuel oil, it is essential to find efficient technologies to remove H2S from synthesis gas prior to its utilization within gas engines for power generation, since their absolute H2S limit is 500 ppm. This thesis intends to provide realistic solutions for clean power generation and simultaneously for the problems of heavy residues in refineries. For this purpose different approaches were adopted and presented. In the literature part, several technologies to remove H2S from synthesis gas were reviewed, such as absorption, adsorption and catalytic hydro treatment. In the experimental part a complete process of gasification, syngas purification by means of absorption and power generation was modeled and simulated with ASPEN plus. Moreover, the overall performance was studied and an economic study based on CAPEX/OPEX was performed in order to evaluate the feasibility of the process and provide reliable results. |
