The paper presents a new thermochemical process for the production of isobutanol, which is an excellent biobased gasoline blendstock. The main feedstock for the process is glycerine, obtained as a byproduct in biodiesel production, being used together with methanol. The process was modeled in...

Conventional azeotropic distillation, consuming very high energy, is mostly used to produce high purity ethanol for renewable energy usage. In this study, the techno-economic comparison between azeotropic distillation (distillation followed by practical azeotropic distillation) and hybrid system...

An original proposal for the deployment of photovoltaic (PV) systems in offshore environments is presented in this paper. Crystalline PV panels are considered where they are deployed on pontoon type structures and there are six case study examples precedent practise of such deployments in lakes...

Renewable Energy Sources (RES) and especially wind energy are seen as an essential part of the future clean energy system. In the present paper, the wind potential of Kythira Island was studied and a techno-economic analysis was done aiming at identifying the optimum solution for the proposed...

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...

In this study, biogas production from the organic fraction of the MSW (OMSW) was simulated in six different scenarios, using Aspen Plus® based on industrial data. The economic evaluations were made using the Aspen process economic analyzer, considering the plant size and the upgrading methods....

The technical, environmental and economic analysis of two small scale biomass fuelled CHP applications is the subject of this study. For this analysis, the process simulation software ECLIPSE is used. Modelling and simulation have been conducted over two configurations: Organic Rankine Cycle...

Olefins are one of the most important platform chemicals. Developing coal-to-olefins (CTO) processes is regarded as one of promising alternatives to oil-to-olefins process. However, CTO suffers from high CO2 emission due to the high carbon contents of coal. In China, there is 7×1010m3 coke-oven...

Coal-fired power plants in China consume nearly half of available coals, and the resulting CO2 emissions cover over 40% of total national emissions. Therefore, reducing the energy expenditure of coal-fired power plants is of great significance to China’s energy security and greenhouse gas...
