1. Strategies for Reduced Energy Use and Cost in Pulp and Paper Mills by Energy Integration of the Paper Drying Process
Abstract : The cost of energy for drying paper is substantial for the pulp and paper industry, and studies of various strategies for energy cost reductions such as increased energy efficiency, increased heat recovery from the exhaust drying air and reduced cost of the process heat are presented in this thesis. The energy use and cost studies were performed using a block-model based simulation tool developed for this specific purpose. READ MORE

3. Solar Assisted Pervaporation (SAP) : A process using membrane pouches and solar energy for the dehydration and preservation of fruit juices in rural and remote areas
Abstract : Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on the small-scale for two main reasons. READ MORE

4. Benefits of Integrated Upgrading of Biofuels in Biorefineries - Systems Analysis
Abstract : As a result of increasing concerns about climate change, there is considerable current interest in increasing use of CO2-neutral biofuel in the energy system. Increased use of biomass fuel requires that it be upgraded in order to facilitate transportation and distribution to end-users. READ MORE

5. The open absorption system : energy savings in different applications
Abstract : The open absorption system is a technique that makes it possible to recover energy in different processes using moist air. In most applications the latent heat in moist air is difficult to recover because of the low temperature. Processes using outdoor air to carry away moisture therefore have high energy demands.
