techno economic analysis of the coal to olefins process in comparison with the oil to olefins process
Applied Energy, 2014Co-Authors: Dong Xiang, Yu Qian, Yi Man, Siyu YangAbstract:Abstract Olefins are one of the most important oil derivatives widely used in industry. To reduce the dependence of olefins industry on oil, China is increasing the production of olefins from alternative energy resources, especially from coal. This study is concerned with the opportunities and obstacles of coal-to-olefins development, and focuses on making an overall techno-economic analysis of a coal-to-olefins plant with the capacity of 0.7 Mt/a olefins. Comparison is made with a 1.5 Mt/a oil-to-olefins plant based on three criteria including energy efficiency, capital investment, and product cost. It was found that the coal-based olefins process show prominent advantage in product cost because of the low Price of its feedstock. However, it suffers from the limitations of higher capital investment, lower energy efficiency, and higher emissions. The effects of production scale, Raw Material Price, and carbon tax were varied for the two production routes, and thus the operational regions were found for the coal-to-olefins process to be competitive.

wood pellets production costs and energy consumption under different framework conditions in northeast argentina
Biomass & Bioenergy, 2011Co-Authors: Augusto Uasuf, Gero BeckerAbstract:Abstract The development of cleaner and renewable energy sources are needed in order to reduce dependency and global warming. Wood pellets are a clean renewable fuel and has been considered as one of the substitutes for fossil fuels. In Argentina, large quantities of sawmill residues are still unused and wood pellets production could be seen as both, as an environmental solution and an extra economical benefit. The general aim of this study was to determine the wood pellets production costs and energy consumption under different framework conditions in northeast Argentina. The specific costs of wood pellets for the different scenarios showed relative lower costs comparing to the ones reported in other studies, ranging from 35 to 47 €/Mgpellets. Raw Material costs represented the main cost factor in the calculation of the total pellets production costs. A lower specific production cost was observed when 50% of the Raw Material input was wood shavings. The specific electricity consumption per metric ton of pellet was lower in scenarios with higher production rate. Lower heat energy consumption was observed in scenarios that have a mixed Raw Material input. The most promising framework condition for Northeast Argentina, in terms of costs effectiveness and energy consumption could be acquired with production rates of 6 Mg/h with sawdust and wood shavings as Raw Material. However, simultaneous increment of the electricity by 50% and Raw Material Price by 100% may increase the specific costs up to 50%.
