About the position

The PhD project is part of the SUBPRO center which is a large 8-year research-based innovation program in the field of subsea processing and production. Industrial partners in SUBPRO include Equinor, Lundin, AkerBP, Neptune Energy Norge, Aker Solutions, DNVGL and Kongsberg Digital. 

The main objective of this project is to make membrane technology feasible for natural gas dehydration subsea operation, and to increase the maturity of the subsea membrane dehydration process. Compared to conventional absorption columns, the gas-liquid contact area density of a membrane contactor unit is much higher, and consequently the membrane unit volume will be smaller. This is important for subsea applications. 

The project proposal is a continuation of recent and ongoing PhD work. The new project work will build on and be an extension of the developed process simulation models in Matlab and HYSYS. Experimental work will also be included as an important part of this PhD, to provide data for the model extension and to validate the new models. In addition to mass transfer of water, the extended models will also describe the mass transfer of other chemical components, like TEG, through the membranes. The transport of TEG into the natural gas stream will be experimentally determined and the suitable membrane materials to reduce TEG loss will be identified. The experimental work will also cover the membrane durability test in the presence of impurities and under subsea operating conditions.

Qualification requirements

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master’s degree or second degree (equivalent to 120 credits) with a strong academic background, or equivalent education with a grade of B or better in terms of NTNU’s grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, postdoctor and research assistant
