Thermo-economic evaluation of bio-ethanol humidification EvGT cycle

The evaporative gas turbine pilot plant (EvGT) has been in operation at Lund Institute of Technology in Sweden since 1997. This article presents the latest development in the evaporative technology, the evaporation of bio-ethanol in a gas turbine power plant as a means to reduce the emission of greenhouse gases. Bio-ethanol is produced from a feedstock consisting of corn-stover, and the bio-ethano

Carrot Juice Processing - Effects on Various Quality Aspects

Popular Abstract in Swedish Färsk morotsjuice har ett högre förädlingsvärde än råa morötter. Färsk morotsjuice har en kort hållbarhet på cirka tre dagar vilket försvårar centraliserad industriell storproduktion. Olika processteg vid tillverkningen av morotsjuice påverkar såväl hållbarhet som näringsinnehåll och utseende. Syftet med detta arbete var att undersöka och karakterisera effekter av olikaCarrots are a cold-weather crop well suited for cultivation in the south of Sweden. Carrots are generally rather inexpensive, with a market price below € 1 /kg (Sweden, 2003), whereas fresh carrot juice has a price of around € 5 /kg. The fresh carrot juice produced today has a short shelf-life of approximately three days, which makes centralised industrial production and distribution difficult, an

Air Traffic Controllers and Incidents: An Explorative Interview Study

An explorative interview study was performed with 21 air traffic controllers having experienced air traffic control incidents (loss of separation between aircraft). The results of the interview study identified the following main factors contributing to the occurrence of incidents: 1) memory malfunctions; 2) concentration problems; 3) distractions; 4) inadequate expectations; 5) deficient phraseol
