1. 1. Improving Cooling Tower Water and Energy Efficiencies based on a New Analytical Method

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Rayan Abboud; [2022]
   Keywords : ;

   Abstract : Cooling towers are largely used in many industrial processes for cooling purposes. The basic concept of a cooling tower includes cooling down water by means of evaporation, thus giving it the terminology “evaporative cooling”. Air mixes with water in a cooling tower and is ejected carrying the heat that is transferred from the water. READ MORE

3. 2. Scrubbing of sulfur dioxide from secondary process gases in a copper smelter

   University essay from KTH/Kemiteknik

   Author : Obiora Okolo; [2021]
   Keywords : sulfur dioxide; scrubbing; smelter; process industry; flue gas desulfurization; svaveldioxid; skrubbning; smältverk; processindustri; rökgasavsvavling;

   Abstract : Processindustrin är den största källan för utsläpp av svaveldioxid (SO2) i Sverige, vilket även inkluderar icke­järnmetallindustrin. Kopparsmältverket Boliden Rönnskär har ett miljötillstånd som tillåter SO2­-utsläpp på maximalt 3500 ton/år, en gräns som Rönnskär har legat nära under de senaste åren. READ MORE

4. 3. Flue gas heat recovery for district heating : Analysis of flue gas condensation on a crematorium facility at Hovdestalund, Västerås.

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Charlie Lindquist; [2021]
   Keywords : ;

   Abstract : This degree project investigates the technical and economic possibility of a heat recovery system on Hovdestalund crematorium. The crematorium will have a solution that allows the facility to become both a producer and consumer to the district heating network. READ MORE

6. 5. Simulation of Hardening of the MahanaKhon Tower Mat Foundation

   University essay from KTH/Betongbyggnad

   Author : Zakaria Kazi-tani; [2019]
   Keywords : Hydration; MahanaKhon tower; mat foundation; young concrete; temperature development; thermal stresses; cracking; fly ash; finite element analysis; COMSOL Multiphysics; Hydratation; MahanaKhon tower; bottenplatta; ung betong; temperaturutveckling; termiska spänningar; sprickbildning; flygaska; finita elementanalys; COMSOL Multiphysics;

   Abstract : Cement hydration is the result of a series of simultaneous chemical reactions occurring during the production of concrete. An excessive amount of heat is generated, which consequently may give rise to thermal stresses and cause early age cracks in concrete that may affect its structural integrity, and load bearing capacity.
