REYST Students MSc Examinations
21.1.2010
Announcement of the REYST MSc-lectures/examinations that will take place Monday January 25, at Reykjavik University.
Location: Reykjavik University, Nautholsvik, Room M 1.21
Title: Biomass gasification in Iceland with the intention of Methanol production - A feasibility study
Time: 10:15
Student: Jón Örn Jónsson
Supervisors: Kristján Vigfússon og Guðrún Sævarsdóttir, Reykjavik University
MSc examiner: Þröstur Olaf Sigurjónsson, Reykjavik University
Abstract:
Gasification is a well known process where carbon based feedstock is partially burned, producing a gaseous mixture that may be used either directly as a fuel, or as feedstock in another process for example for synthetic fuel production. This study focuses evaluating the feasibility of synthetic fuel production in Iceland, based on biomass. The main advantage of the location in Iceland being reasonable prices of renewable electric energy.
Title: Automatization of a geothermal power plant in Djibouti - type of suitable control equipment and degree of automatization for Djibouti
Time: 11:15
Student: Houssein Osman Guelleh
Supervisor: Professor Magnus Þór Jónsson, University of Iceland
Other MSc committee members: Gunnar Hjartarson, Reykjavik Energy Invest and Tómas Guðmarsson, Reykjavik Energy
MSc examiner: Rúnar Unnþórsson, Keilir
Title: Heat recovery from the exhaust gas of aluminum reduction cells
Time: 13:00
Student: Martin Fleer
Supervisors: Guðrún Sævarsdóttir, William Harvey, Reykjavik University and Halldór Pálsson, University of Iceland
MSc examiner: Jón Hálfdanarson, University of Iceland
Abstract:
Close to half the total energy input to the Hall-Héroult process leaves the cell as waste heat,
which may be harnessed for useful purposes. The heat loss is by several paths of which the
exhaust gas carries the second largest energy amount and is the most accessible. An
experimental analysis of the exhaust gas was conducted at the 270,000 metric tons per year
Nordural aluminum smelter in Iceland. The district heating potential of heat recovery from the
exhaust gas was assessed for the local community of Akranes. For this smelter the heat
recovery potential is up to 55 MWth, sufficient to supply around 16,000 homes with base load
for heat and hot tap water.
The heavy dust content of 0.26-0.38 g dust/kg exhaust gas calls for careful antifouling
provisions in the design of the heat exchangers. Particulates were isokinetically sampled in
front of the dry scrubber and analyzed for chemical properties and size distribution along with
scale buildup on a fouling probe.
Title: Carbon footprint assessment and its reduction efforts: The case of Blue Lagoon company
Time: 14:00
Student: Indra Suryata
Supervisors: Halldór G. Svavarsson, Reykjavik University and Sigurbjörn Einarsson and Ása Brynjólfsdóttir, Blue Lagoon
MSc examiner: Guðrún Sævarsdóttir, Reykjavik University
Abstract:
In general, energy efficiency has shown inconceivable results, and is likely to show more success stories ahead in delivering valuable carbon and cost savings for business. However, the effort to mitigate the climate change will require more fundamental changes to the way that business delivers products and services to the end customer.
This report will describe a practical approach to reduce carbon emissions in the Blue Lagoon Company, by understanding and optimizing emissions across full product supply chain. It is believed that supply chain intervention approach is a new ways of reducing carbon emissions, just as companies have been using supply chain analysis to deliver financial benefits for many years.
The thesis may be divided into two parts, one major part which deals with life cycle analyses of product in respect to green houses gas emission and one minor part which explores the possibilities of CO2 mitigation from Svartsengi geothermal power plant by microalgae which grow naturally at the Blue Lagoon site. A system has been designed for the reduction process and parameters for growth were varied to optimize the process.
The lectures are open for all.
