COSMO-based process simulations with Aspen Plus/Aspen HYSYS are used, for the first time, to a priori estimate the thermodynamic performance of ammonia absorption refrigeration cycles using ionic liquids as absorbents. This allows not only broadening the criteria set used to select/design ionic...

A rate-based model, RateFrac, in Aspen Plus process simulator, is used to simulate the CO2 absorption and regeneration processes of a research scale pilot plant. The simulation results of the CO2 absorption and regeneration predicted by the rate-based model are in good agreement with the...

Worldwide energy production requirements could not be fully satisfied by nuclear and renewables sources. Therefore a sustainable use of fossil fuels (coal in particular) will be required for several decades. In this scenario, carbon capture and storage (CCS) represents a key solution to control...

For large volumes of carbon dioxide (CO2) onshore and offshore transportation, pipeline is considered the preferred method. This paper presents a study of the pipeline network planned in the Humber region of the UK. Steady state process simulation models of the CO2 transport pipeline network...

Brown algae, considered as the third generation biomass, offer several advantages over lignocellulosic biomass. However, the current high cost of seaweed cultivation hampers the industrialization of macroalgae-based biofuel production. The aim of this study is to determine the maximum dry...

This paper estimated the cost curve of energy saving and CO2 emissions reduction in China’s iron and steel sector. Forty-one energy saving technologies which are widely used or popularized are selected, their investments, operation costs, energy savings and CO2 abatement are collected and the...

This paper is focused on methods to indicate the environmental impact in terms of air pollutants of CHP (Combined Heat and Power) systems. The aim is to combine the energy saving achievement with information concerning the environmental benefit, in comparison with the non-CHP scenario.

The EU regulations on energy saving have been implemented in Italy with the adoption of the North-European super-insulated model that led to the construction of buildings not much related to their climatic context. The European Directives 2010/31/EU and 2012/27/EU highlighted the importance to...

The major challenge to the large-scale commercialisation of hybrid electric vehicles is their high initial and operating costs, although a mild hybrid is generally cheaper than a full hybrid of the same performance. Hence, the average operating efficiency of the internal combustion engine of a...
