PhD scholarship in Biogas Upgrading (CO2 Capture) Simulation through Experimental Work and Thermodynamic Modelling

Center for Energy Resources Engineering (CERE), Department of Chemicaland Biochemical Engineering, Technical University of Denmark (DTU) seeks a PhDto support our BioCO2 project. The proposed work will be conducted incollaboration between DTU Chemical Engineering and the project partners: UnionEngineering and Danish Gas Technology Center. The position is for a period of 3years.

Denmark has a great need to substitute our declining North Sea gasproduction by cleaner alternative fuels. We have a current potential tosubstitute 10% of our oil, gas, and coal usage by sustainable biogas. Biogas isproduced from biological resources like manure and wastewater sludge.Untreated, it typically contains 30% to 40% CO2 and impurities.Biogas can be upgraded to bio-methane, which permits distribution through thenatural gas grid. However, in this process CO2 is produced andemitted into the atmosphere.

Responsibilities and tasks
The aim of your project will be to develop a simulation engine, whichwill further be used in the BioCO2 project by your colleges for process design,simulation, and optimization. You will expand existing DTU software for thispurpose.

The development will include a new DTU solvent technology, which hasproven to give reduced energy consumption during solvent regeneration. In thistechnology maturation, you will apply an existing DTU solvent methodology. Inorder to perform the software development you will need to extend existingthermodynamic models and conduct measurements in the lab in relation to CO2solvent properties (VLE, SLE, heat of absorption etc).

One of your final tasks will be to initialize Aspen Plus processsimulation in close collaboration with Union Engineering and a colleague atDTU, who are experienced within the same field of technology.

Your responsibilities will include sub-reporting for the fundingagencies.

Objective and purpose of the project
The purpose of the project is to create and demonstrate a financiallyviable technology, which will enable the upgrading of biogas to natural gasgrid quality and simultaneously permit the reuse of the CO2 forother purposes, such as synthetic biofuel and food.

Project contents
The task will be to gain experience from existing thermodynamic andexperimental knowhow at DTU. You will gain knowledge from other researchersworking in the same field of technology development. You are expected to applyexisting knowledge from DTU and succeed in developing a rate-based model forprocess simulation.

Relation to other projects
You will be a member of the CERE research group. Youwill be working in close collaboration with Associate Professors Philip Fosbøl& Kaj Thomsen in your daily work. You can draw on years of experience andknowledge on CO2capture technologies. The software basis you willdevelop further for this project is already available. Your project is onewithin a publicly funded framework called BioCO2.

Candidates should have a two-year master’s degree (120 ECTS points) or asimilar degree with an academic level equivalent to a two-year master’s degree.There will be a focus on your experience with programming, thermodynamics, andchemical property measurements in the lab – and on the number of publicationsyou have created.

Approval andEnrolment
The scholarship for the PhD degree is subject to academic approval, andthe candidate will be enrolled in one of the general degree programmes at DTU.For information about our enrolment requirements and the general planning ofthe PhD study programme, please see the DTU PhD Guide.  

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