Models for hydrolysis, fermentation and concentration process, production and utilization of biogas as well as lignin gasification are developed to calculate the heat demand of ethanol production process and the amounts of heat and power generated from res ...
The thermochemical conversion and recycling of hazardous solid waste materials is investigated using high-temperature solar process heat. Two important sources of wastes contaminated with heavy metal oxides are considered: (1) electric are furnace dust (EA ...
The most common energy application for biogas is on-site power generation using gas engine units. The introduction of a bottoming cycle based on Scroll expander Organic Rankine Cycle (ORC) technology within a biogas plant is of high interest since the exce ...
This paper introduces a novel of mini-hybrid solar power plant integrating a field of solar concentrators, two superposed Organic Rankine Cycles (ORC) and a (bio)Diesel engine. Turbines for the organic Rankine Cycles are hermetic scroll expander-generators ...
In the context of resource conservation, incineration of domestic wastes is a technique allowing an interesting potential in energy valorization. However, because of the variability (annual, monthly) in quality and quantity of raw material, one of the char ...
This paper presents a methodology aimed at improving the energy efficiency of a brewery applying process integration techniques. The different steps of the analysis are presented. The first step is the identification of the process energy requirements and ...
This study reports on the combination of solid oxide fuel cell (SOFC) generators fueled with biogas as renewable energy source, recoverable from wastes but at present underexploited. From a mobilisable near-future potential in the European Union (EU-15) of ...
Biogas as renewable source of energy is underexploited. We extrapolate the potential recoverable from waste streams in the EU-15 to 769 PJ (17.5 Mtoe), of which under 10% is used (1.7 Mtoe). SOFC can promote the valorisation of biogas in small CHP installa ...
