• Model Based Early Kick/Loss Detection and Attenuation with Topside Sensing in Managed Pressure Drilling 

  Jinasena, Asanthi; Holta, Haavard H. F.; Jondahl, Morten Hansen; Welahettige, Prasanna Kumara Welahetti; Aamo, Ole Morten; Sharma, Roshan; Viumdal, Håkon; Lie, Bernt (Peer reviewed; Journal article, 2020)

  Early kick/loss detection is a crucial part of safe well control, and it plays a major role in the reduction of risk and non-productive time in drilling. In conventional drilling, topside sensing is used for early kick/loss ...

• Piping Components: An Analysis of the Critical Dimensions 

  Anderson, Gwen; Gjerde, Ida Helene; Helgesen, Sondre Luca; Jecmenica, Mladen; Thapa, Rajan Kumar (Peer reviewed; Journal article, 2020)

  Pipe components such as elbow, tees, and weldolets are produced at various places in the world. Although the component is produced in accordance with standard ASME (American Society of Mechanical Engineers) B16.9, measurements ...

• Computational modeling of fluidized bed behavior with agglomerates 

  Jakobsen, Krister; Jaiswal, Rajan; Furuvik, Nora Cecilie Ivarsdatter; Moldestad, Britt Margrethe Emilie (Journal article; Peer reviewed, 2020)

  Fluidized bed reactors can be used for biomass gasification. The product from biomass gasification is syngas, which can be used for production of bio oil. The main challenge when using fluidized bed for gasification is ash ...

• Simulation of a purification plant for pyrolysis gas based on plastic waste 

  Quaredaghi, Ebrahim; Ronasi, Sara; Moldestad, Britt Margrethe Emilie (Peer reviewed; Journal article, 2020)

  This study focuses on exctracting ethylene and propylene from other componenents in the pyrolysis gas mixture of plastic waste. Selective absorption of ethylene and propylene from the gas mixture by using a silver nitrate ...

• Simulation of entrained flow gasification reactor with Multi Phase Particle in Cell (MP-PIC) approach 

  Timsina, Ramesh; Thapa, Rajan Kumar; Moldestad, Britt Margrethe Emilie; Eikeland, Marianne Sørflaten (Journal article; Peer reviewed, 2020)

  An Entrained flow gasification reactor is studied in this work. Entrained flow reactors are best suited for a feed with small particles at large capacity, at high temperatures, pressures and with short residence time. This ...
