The invention relates to a packing assembly for a material exchange column, comprising at least one structured packing plate and a container in which the at least one structured packing plate is arranged. The at least one structured packing plate has packing packets. Each packing packet has interconnected packing sheets. The packing sheets are corrugated and have corrugation peaks and corrugation valleys. Adjacent packing sheets contact each other at the corrugation peaks. Additional corrugated packing sheets are added between the packing packets such that the at least one packing plate is pretensioned against the container in a radial direction thereof. Both the corrugated packing sheets of the packing packets as well as the additional corrugated packing sheet added between the packing packets are arranged solely on a common preferred plane or parallel thereto.

Packing assembly, material exchange column, and method

Methods and apparatus for processing fluid from a well are described. A first wall portion may define a first region and a second wall portion may define a second region, fluid from said well being let through those regions. Heating of said first wall portion may be performed to release wax from said first wall portion into said fluid at said first flow region. During said heating, cooling of said fluid at said second flow region may be performed to cause wax from said fluid to deposit on said second wall portion.

Processing fluid from a well

A method and apparatus for determining contents of a conduit containing at least one fluid is described. The conduit may be at least partially defined by at least one wall portion. The wall portion may be cooled. After cooling said, the temperature at least one temperature sensor located adjacent to the wall portion may be measured. A characteristic of said contents is determined based on said measured temperature at the or each temperature sensor.

Characterizing contents of conduits, in particular multiphase flow conduits

A method and apparatus for determining multiphase flow characteristics inside production equipment containing at least two fluids. A pulse of heat from a heat source adjacent to the production equipment is provided, and a thermal response to the pulse is measured at each of a plurality of temperature sensors located adjacent to the production equipment. The thermal response measurement includes a time constant obtained from a measured decline in the temperature after the pulse of heat has been provided. The measured thermal responses are used to determine parameters of a fluid contained in the production equipment in proximity to each of the temperature sensors. The determined fluid parameters are in turn used to determine multiphase flow characteristics.

Characterizing multiphase fluid flow

The present invention concerns a method for measuring the thickness of any deposit of material on the inner wall of a structure conducting a fluid stream of hydrocarbons, the method comprising the steps of: applying a first heat pulse or continuous heating to at least one first section of the structure removing deposits on the inner wall of the first section of the structure; applying a second heat pulse to both the first section of the structure and at least one second section of the structure, the first and second sections being spaced apart, which heat pulse does not loosen any deposit of material in the second section; measuring the temperature of the wall of the structure or the fluid during the second heat pulse at both the first and second sections; and determining the thickness of any deposit of material on the inner wall of the structure at the second section based on the measured temperatures. The present invention also relates to a corresponding device and arrangement.

Method and device for measuring deposit thickness

A method of measuring the thickness of any deposit of material () on an inner wall () of a structure (). The method comprises: (a) causing vibrations in the structure; (b) detecting said vibrations in the structure; (c) determining a resonance frequency of the structure based on the detected vibrations; and (d) determining the thickness of any deposit of material on the inner wall of the structure based on the determined resonance frequency.

Method and device for measuring the thickness of any deposit of material on an inner wall of a structure

A method is provided for measurement of the thickness of any deposit of material on the inner wall of a pipeline at least partly filled with a medium including hydrocarbons, the medium being for instance oil or natural gas, wherein the method includes: projecting infrared light onto the inner wall of the pipeline along a line corresponding to the intersection between the inner wall of the pipeline and a cross-sectional plane of the pipeline; registering an image of the infrared light projected on the inner wall of the pipeline; and determining the thickness of any deposit of material on the inner wall of the pipeline based on the registered image.
