The Department of Chemical and Biochemical Engineering, Center for Energy Resources Engineering (CERE), invites applicants for a PhD position in Kinetics of Scale Formation.

CERE is Denmark’s leading research center in the areas of EOR, flow assurance, CCS and petroleum geoscience. CERE is an independent, university based, research unit with more than 30 years of expertise in the field. The CERE co-workers are a mix of internationally renowned scientists and the sharpest young talents from different scientific communities around the world.

Scale formation in industrial production equipment poses a general challenge. It tends to build up on pipe walls and can cause a failure of safety valves or a complete stop of production due to loss of internal diameter of the pipe from excessive scale formation. Scales may also cause under deposit corrosion and there is a great need to understand how fast the scales are formed.

The scales in focus during this study are CaCO3 and FeCO3. The aim of this study is to determine scale formation kinetics. Existing equipment and methods need to be further developed.

The knowledge generated in this project is to be used for model development giving the possibility to better predict scale formation in the future. The objective is to reduce the cost of down time by developing methods to predict the rate of scale formation in production equipment. 

Responsibilities and tasks
An experimental method and an analytic chemical technique to determine the rate of scale formation should be developed. 

  • Measurements should be conducted under conditions allowing the determination of the rate of scale formation under varying conditions such as
    • Temperature
    • CO2 partial pressure.
    • Brine composition
  • The rate of scale deposition on surfaces and the rate of scale formation in the bulk brine should be determined separately.
  • Advanced thermodynamic models are available for support.
  • Existing knowledge on scale formation kinetics from literature is analysed and refined for use in the project.
You will be a member of the CERE research group supervised by associate professors Philip Fosbøl and Kaj Thomsen, DTU Chemical Engineering. In the CERE research group, you can draw on years of thermodynamic experience and knowledge of scale formation.

You will have the chance to visit external research institutions to gain knowledge on the topic.

Qualifications
Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree. Master's degree in analytical or physical chemistry, chemical engineering, environmental sciences, or similar is required.

In addition, we look for applicants with:
 
  • Exceptional skills in experimental physical chemistry/chemical engineering/environmental science;
  • Experience with and a strong interest in setting up advanced experiments;
  • Experience with fluid dynamics and flow systems;
  • Experience with modeling based on experimental data
  • Interest in applied research;
  • Ability to work in a multi-disciplinary environment;
  • Excellent writing and communication skills in English;
Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide

Assessment
The assessment of the applicants will be made by Associate Professors Philip L. Fosbøl and Kaj Thomsen.
