Thermopervaporation for regeneration of triethylene glycol (TEG):Experimental and model development
Journal of Membrane Science, 2019Co-Authors: Kristin Dalane, Magne Hillestad, Natalie Therese Josefsen, Luca Ansaloni, Liyuan DengAbstract:Abstract Subsea Processing is getting increased interest in the oil and gas sector as it can provide broader exploration of the oil and gas with a lower environmental footprint. Dehydration of natural gas with the use of triethylene glycol (TEG) is one of the main Processing step for natural gas treatment to avoid transportation problems caused by the presence of water. Distillation is a commonly used technology for topside regeneration of TEG. However, for Subsea operation alternative technologies are required to avoid complexity and the large energy consumption. Membranes are evaluated as promising solutions as they fulfil the Subsea design criteria of compact design, flexible operation, and high modularity. In this work, the use of thermopervaporation for regeneration of TEG has been assessed. A mathematical model of a plate-and-frame thermopervaporation membrane module has been developed, where two-dimensional flow are considered for the liquid phases and the air gap is treated as a stagnant phase. Experimental pervaporation data were provided for the tuning of the model and the development of a temperature dependent permeability correlation. In addition, the effects of operation conditions and membrane properties on the separation performance were investigated. From this evaluation, it is clearly shown that the air gap significantly affects the separation performance and is a key parameter in the design of the thermopervaporation module.

Subsea natural gas dehydration with membrane processes: Simulation and process optimization
Chemical Engineering Research and Design, 2019Co-Authors: Kristin Dalane, Magne Hillestad, Liyuan DengAbstract:Abstract Subsea Processing enables broader exploration of oil and gas reservoir, giving an increased focus on developing alternative processes for Subsea oil and gas treatment. This work provides a first evaluation of a new proposed Subsea natural gas dehydration process with the use of a membrane contactor with triethylene glycol (TEG) for dehydration of the natural gas in combination with thermopervaporation for regeneration of the TEG. Simulation models are developed in Aspen HYSYS V8.6 and process optimization is performed on three different process designs with respect to staging of the regeneration. By introducing two thermopervaporation units in series the TEG flow rate is reduced by 55%, the membrane volume by 14.6% and the energy demands by 37.8%, compared to a design with one thermopervaporation unit. However, increasing the number of regeneration stages increases the complexity as additional heaters are introduced.

Potential applications of membrane separation for Subsea natural gas Processing: A review
Journal of Natural Gas Science and Engineering, 2017Co-Authors: Kristin Dalane, Zhongde Dai, Gro Mogseth, Magne Hillestad, Liyuan DengAbstract:The petroleum industry is receiving increased interest in Subsea oil and gas Processing as it is running out of easily accessible oil and gas reservoirs. Membrane processes fulfill Subsea design requirements with a simple and compact design. However, today no application has been used Subsea. This paper reviews the advances in membrane separation to date in view of the industrial needs for Subsea separation. Some potential applications of membranes and membrane processes in Subsea Processing are proposed based on the topside experience. Two Subsea natural gas treatment processes, namely natural gas dehydration and acid gas removal, are discussed in details with respect to the advantages and challenges in the implementation of membrane technology Subsea, including future research perspectives. This study can be a starting point in connecting the two research areas (Subsea separation and membrane technology) together.
