Investigation of the effect of incorporating Real Options in the Valuation of Petrochemical Plants in Iran, M.Sc. Thesis Sharif University of Technology ; Bahramgiri, Mohsen
Real option is one of most promising and crucial concepts in corporate valuation and budgeting process. They are very similar to financial options except that their intrinstic values are calculated based on a company’s practical flexibilities rather than financial contracts. Most previous publications in this field are related to upstream sectors of oil, gas, or mining as well as high-tech industries. The application of this concept in chemical industries has been poorly investigated, and the majority of those limited number of papers have evaluated real options in down-stram sectors. Thus, the application of real options in midstream parts of chemical industry was not thoroughly...

Despite the growth in Iran’s petrochemical production, most of the plants are concentrated upstream; although the government has made various interventions to promote industrial development. The literature review shows that government intervention is necessary to solve market failures, especially in developing countries; but it should be tailored to the specific context and especially the distribution of the power. Most experts believe that the cause of the above phenomenon is feedstock rent and the reason for its continuation is the political influence of petrochemical companies. While not rejecting this view, we try to provide policy recommendations by looking more closely at the issue and...

In this study, we introduce a systematic approach for valuation of Technology development projects by applying a discrete model of real options valuation. This framework is then applied to a real technology development project. The estimate of volatility is the most important argument that it is difficult to calculate. Data from the project’s feasibility study is gathered and classified in an appropriate format to be ready for simulation. Then uncertainty parameters are identified. The data is separated and their impacts on annual cash flows are considered. Volatility of the whole project is estimated to be relatively high. This is an advantage for the proposed method. In this project,...

Catalytic paraffin dehydrogenation for manufacturing olefins is considered to be one of the most significant production routes in the petrochemical industries. A reactor kinetic model for the dehydrogenation of propane to propylene in a radial-flow reactor over Pt-Sn/Al2O3 as the catalyst was investigated here. The model showed that the catalyst activity was highly time dependent. In addition, the component concentrations and the temperature varied along the reactor radius owing to the occurring endothermic reaction. Moreover, a similar trend was noticed for the propane conversion as for the propylene selectivity, with both of them decreasing over the time period studied. Furthermore, a...
