The paper examines design and operating data of current concentrated solar power (CSP) 10 solar tower (ST) plants. The study includes CSP with or without boost by combustion of natural gas 11 (NG) and with or without thermal energy storage (TES). The study then reviews the novel trends to 12 produce better ratio of solar field power to electric power, better capacity factor, better matching of ...

Alternative energies nowadays have to be more competitive than energy derived from fossil fuels. In this study, the supply chain design problem for a biomass plant is considered. In order to reduce the cost per kWh of energy produced, the whole supply chain involving the biomass plant is modeled. A two-steps methodology, consisting in two sequential simulation experiments, is illustrated. The p...

An efficient way for producing power, heat, and cooling while reducing CO2 emissions is through trigeneration. The emitted CO2 from trigeneration plant can be further reduced by producing biochar, which contributes negative carbon footprint to the system through sequestration of biomass carbon as char. This requires a gasification process to be added in the trigeneration system to produce bioch...

abstract different strategies are existed for adjusting with water shortage, of which the strategy of suitable policies adoption by determining optimum production function can be mentioned. water shortage and quality degradation of soil and water resources is one of main factors of production reduction. therefore, this study was carried out for determination of tomato sensitivity coefficients a...

Conceptual process design phase is of prime importance to the performance and the profitability of a new or retrofit process. It is also a highly complex task with a large number of process alternatives, a large variety of requirement specifications and large differences in temporal and spatial scales. Therefore, it is essential to continuously improve design methods. The research should not on...

the purpose of this study is evaluation and improvement of production functions to estimate alfalfa yields under different deficit irrigations conditions and determination of “production of yield - water use” in qazvin plain. this investigation was applied by factorial experiment in a randomized complete block design with four water treatments including e4, e3, e2, and e1, respectively, equal t...
