1. Jetbrandtester och vätgas : En litteratur- och intervjustudie om försök med vätgasjetflammor
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Vätgas är en energibärare som kan vara en av pusselbitarna i omställningen till en mer klimatneutral värld. Infrastrukturen byggs ut, industrin växer och vätgasfordon blir vanligare. LÄS MER
2. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products
Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskapSammanfattning : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. LÄS MER
3. Fastläggning av arsenik med nollvärt järn i mikrostorlek : Uppföljning av ett pilotskaleförsök
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : Land contaminated with arsenic is a major problem as arsenic is toxic and poses a major health risk to both humans and animals. There are several remediation methods, both in-situ and ex-situ, to prevent and deal with pollution problems in different ways. LÄS MER
4. Undersökning och täthetsmätning av små mekaniska komponenter.Leakage testing and analysis on small mechanical devices
Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : The work was conducted at Saab Dynamics AB in Karlskoga, and the focus was to investigate and evaluate available methods for leak detection of small mechanical components, such as Electro-Explosive Devices (EEDs) and fuzes in warheads and using these methods to investigate whether they work for this purpose. At the start of the project, the problem was that these mechanical components were exposed to contamination, such as moisture and dust but also TNT exudate, plasticizers, gunpowder residues, etc. LÄS MER
5. New process for leak detection in truck pneumatic systems during production using an ultrasound camera
Master-uppsats, Uppsala universitet/Industriell teknikSammanfattning : The process of producing compressed air in the industry today is highly energy inefficient. Up to 75 % of the energy spent on producing compressed air to the compressed air systems (CASs) is wasted. Out of the produced air, 24 % is wasted due to air leaks. LÄS MER
