Online monitoring of wax deposition in sub-sea pipelines
, 2011 This paper describes a new technology (heat pulse wax monitoring) to monitor wax deposition in sub-sea pipelines continuously. The equipment that has been tested in a lab rig consists of a heating element and a temperature sensor which are installed at a

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film
Advanced Functional Materials, EarlyView.ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Numerical simulation of wax deposition in pipelines
, 2020 Crude oils are complex mixtures of hydrocarbons. Among these components, high molecular weight paraffin (waxes) and asphaltenes may cause severe flow assurance issues in production and transportation subsea pipeline systems.
