Oxy-fuel combustion technology is an attractive option for capturing carbon dioxide (CO2) in power generation systems utilizing hydrocarbon fuels. However, conventional atmospheric oxy-fuel combustion systems require substantial parasitic energy in the compression step within the air separation...

Multi-generation facilities are almost always part of a local production scenario, i.e., a local area (district, city, regional, national, interstate) energy system providing end users with electricity, residential heating or air-conditioning, industrial process steam, desalinated water, and/or...

The interest in hybrid power production facilities, based on the integration of renewable resources and conventional fossil fuels, is rapidly rising. The question of what fraction of the electricity produced in such facilities is to be considered as produced from the renewable resources is still...

Growing concerns over greenhouse gas emissions have driven extensive research into new power generation cycles that enable carbon dioxide capture and sequestration. In this regard, oxy-fuel combustion is a promising new technology in which fuels are burned in an environment of oxygen and...

Coal–CO2 slurry feed has been suggested as an attractive alternative to coal–water slurry feed for single-stage, entrained-flow gasifiers. Previous work demonstrated the system-level advantages of gasification-based plants equipped with CO2 capture and CO2 slurry feed, under the assumption...

Conventional two-channel ITM (ion transport membrane) reactors applied to oxy-combustion, face the potential drawback of high thermal gradients and high local temperatures, which can result in membrane damage. In such reactors, air flows on the feed side and fuel are introduced on the permeate...

A general method for the allocation of resources and products in multi-resource/multi-product facilities is developed with particular reference to the important two-resource/two-product case of hybrid fossil & solar/heat & power cogeneration. For a realistic case study, we show how the method...
