New Projects

Comparison of Electrolyte Models

A two month project on “Comparison of Electrolyte Models” was initiated on the 1st of July. The project was co-sponsored by IVC-SEP and the three consortium members Akzo-Nobel, Shell, and SQM. Dr. Yi Lin who just finished his PhD. Project in the group was hired for this project. The four activity coefficient models were:

•           The commercial implementation of the electrolyte NRTL model (Chen et al., Aspentech)

•           The commercial implementation of the OLI model (Anderko et al., OLI)

•           The LIQUAC/LIFAC model (Gmehling et al.)

•           The Extended UNIQUAC model (Thomsen et al., IVC-SEP)

The performance of these models in reproducing experimental binary and ternary solid-liquid and vapor-liquid equilibrium data and in predicting multi-component data was compared. Also calculations of freezing point depression data, boiling point elevation data, and calculations in mixed solvent systems were compared. It was observed that the Extended UNIQUAC model performs best in correlation and in prediction compared with the other models examined in this study. The OLI model is number two and the electrolyte NRTL model is number three. The LIQUAC/LIFAC models can not be implemented based on the information published by the authors of these models.

Evaluation of a chilled ammonia process for CO2 capture

A three month project on “Evaluation of a chilled ammonia process for CO2 capture” was initiated on 6th of July. This project was sponsored by DONG Energy and Vattenfall. Victor Darde who just finished his Master project a few days before was employed in this project.

An alternative process for the capture of CO2 from flue gas will be evaluated in this project. This new patented process which uses an aqueous solution of ammonia for the absorption of CO2 seems to have some advantages compared with processes using aqueous solutions of alkanolamines or potassium carbonate. This project will consist of a literature study to find information about the kinetics of this process compared to the kinetics of alternative processes. In addition calculation of phase equilibrium and energy balances will be performed based on the Extended UNIQUAC model.

After finishing this project Victor Darde is expected to begin an Industrial PhD with DONG Energy on January 1, 2008. The supervisors from IVC-SEP will be Kaj Thomsen, Erling H. Stenby and Georgios Kontogeorgis. The working title of this project will be “CO2 captures with aqueous ammonia”.

The ADORE project

The ADORE project – ADvanced Oil REcovery methods – is a recently-funded 5-year project in the area of advanced methods for oil recovery, specifically thermal recovery and chemical flooding. The project is highly interdisciplinary and will comprehensively cover phase, transport and reaction engineering properties of the relevant processes as well as rock mechanical aspects. Large projects in numerical methods will also be carried out to ensure rapid integration of research results into commercially useful software products.

The Research Council for Technology and Production Sciences (FTP) has granted Professor Erling H. Stenby 14.7 million Danish kroner to carry out the project. Additional funding will also be provided by Mærsk Oil and Gas and DTU. The project will fund six PhD projects and two postdocs and is a collaboration between DTU, GEO, Stanford University and the University of Southern California. At DTU the collaborating institutions are IVC-SEP at KT, IMM and MEK. Four IVC-SEP faculty will participate in the project – Professor Erling Stenby, Reader Michael Michelsen and Associate Professors Alexander Shapiro and Nicolas von Solms.

Study trip to Norway

During the period June 18-22 the IVC-SEP study trip to Norway took place. The first two days we spent with the University of Bergen where the CIPR group supervised by Arne Skauge held a seminar with lectures from both CIPR and IVC-SEP. Though different speakers and topics we got a very good idea and an overview of what is going on in the CIPR group and at the same time gave an overview of the main activities of IVC-SEP. We also had a guided tour through their laboratories and among this we visit their very impressive virtual reality simulation room.

The whole group in front of the University in Bergen.

After two days in Bergen we flew to Trondheim were we visited Statoil. Here we had a seminar also with presentations from both Statoil and IVC-SEP and a

very interesting guided tour through the laboratories. On the last day we visited the Norwegian University of Science and Technology (NTNU). The group of Prof. Johan Sjöblom who is the head of the Ugelstad Laboratory at NTNU was the first stop. Here presentations and a guided tour through their laboratories also gave a very good impression of their work. After that we visited Professor Halvard Svendsen and the impressive CO2 Capture activities.

The IVC-SEP Summer School ”Petroleum Fluids. Properties and Production”

The IVC-SEP Summer School “Petroleum Fluids. Properties and Production” took place at the Department for Chemical Engineering from 6 to 24 August, 2007. Associate Professor Alexander Shapiro was responsible for its organization.

The School has attracted 18 participants, the half of them being outside the DTU. The four participants represented the industry: Eni (Italy), Rambøll Olie og Gas (Denmark), and Sudapet Co. (Sudan). The teachers also represented both IVC-SEP and external institutions/companies. Apart from Nicolas von Solms, Kaj Thomsen, Wei Yan, Alexander Shapiro and Erling H. Stenby (IVC-SEP), the teachers at the course were Francois Montel (Total, France) and Kristian Jessen (University of Southern California, U.S.A.).

The school was generally positively evaluated by the participants, who appreciated high level of teaching and relevance to practical problems.

IEA EOR Workshop and Symposium 2007

During the period 4 – 7 September IVC-SEP organized the 2007 IEA EOR Workshop and Symposium on behalf of the Danish Energy Authority. Professor Erling H. Stenby currently the chairman of the Executive Committee of this collaboration. The meeting took place at the Quality Hotel Marina in Vedbæk, Denmark. The Workshop part of the meeting the first two days is a closed meeting with representatives from all over the world and the topic of this years meeting was “Offshore EOR – Technology and Economy”. On Friday 7 September coworkers from Danish companies were invited to participate in the Symposium with opening by Deputy Director General of the Danish Energy Authority, Anne Højer Simonsen and presentations from both Danish and foreign representatives. The meeting was very successful and brought out the newest research results in many different EOR technologies.

Discussion Meeting 2008

I am happy already now to be able to announce that next years IVC-SEP Discussion Meeting will take place during the period 16 – 18 June at Hotel Kolle Kolle: http://www.kollekolle.dk/view.asp?ID=13729
