3. Design of a Polygeneration system in Filipinas ETCR, Colombia
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : This project has addressed the design of a cost-effective Polygeneration system that guarantees a continuous, equitable and environmentally friendly energy supply for the rural settlement of Filipinas ETCR, (in Spanish, Espacios Territoriales de Capacitación y Reincorporación) Colombia, which is currently not achieved, due to a system that relies on the national electricity grid (with numerous outages) and on LPG (Liquefied Petroleum Gas) and wood to meet the thermal demand, mainly for cooking. For this purpose, in addition to the current energy supply situation, the energy demand according to type (electricity and heat) and sector (residential, commercial and agro-livestock) is characterized.

5. Stabilizing biogas processes at high ammonia : effects of acetate pulse-feeding on the microbial population
University essay from SLU/Department of Molecular SciencesAbstract : This study investigated the problem of ammonia inhibition in biogas reactors, commonly occurring when protein rich substrates are used in anaerobic digestion processes. Ammonia inhibition is one of the foremost causes of failure in anaerobic digestion, leading to process instability, with symptoms commonly expressed as; reduction in biogas produced, decreased methane content in the gas and accumulation of volatile fatty acids.
