Improving well production performance by using realtime wash desalting planning tool WDPT in the North Sea

Due to natural depletion many mature fields are currently suffering from productivity issues due to halite precipitation in the North Sea. Main actions to prevent or solve this type of scaling issues include increasing flowing pressures (topside choking or velocity strings), but often considered easiest and most economical are fresh water washes...

Comparison of structured adsorbents for theadsorptive isolation of food ingredients from largestreams

We present guidelines for the configuration of industrial scale chromatographic separationof small molecules. We compared the performance of different axial packed beds, chan-neled monoliths and a continuous monolith assuming silica as base material. The calculatedmass transfer rates were used to calculate the height of a theoretical plate (HETP...

A way to reduce pressure drop in once-through micro-evaporators

This investigation explores the possibilities to reduce the pressure drop of a single-channel micro-evaporator. The availability of micro-technology to create three-dimensional structures at a micro-meter scale opens opportunities to better control process conditions in once-through boilers. However, process miniaturization possesses some...

Field study of a Brownian Demister Unit to reduce aerosol based emission from a Post Combustion CO2 Capture plant

Emission of solvent and its degradation products from a typical absorption-desorption based Post Combustion CO2 Capture (PCCC) process is inevitable and thus, an area of growing concern. Recently, it has been pointed out that emissions can also occur by means of aerosol droplets. Conventional counter-measures such as a water wash and a demister...

Time-dependent inversion of surface subsidence due to dynamic reservoir compaction

We introduce a novel, time-dependent inversion scheme for resolving temporal reservoir pressure drop from surface subsidence observations (from leveling or GPS data, InSAR, tiltmeter monitoring) in a single procedure. The theory is able to accommodate both the absence of surface subsidence estimates at sites at one or more epochs as well as the...

3-D finite element model for gas-assisted injection molding Simulations and experiments

Although gas-assisted injection molding (GAIM) has been practiced in industry for more than a decade, the process is not completely understood, particularly with respect to the gas penetration mechanism. Consequently, mold design and process control are often governed by trial-and-error, and reliable information on the gas distribution and the...

Influence of turbulent grazing flow on the impedance of an opening

In this paper, the impedance of a rectangular opening submitted to a turbulent grazing flow is investigated experimentally. The opening is located in a flat plate where a turbulent boundary layer flow develops. The impedance is measured with a two-microphone measuring pipe installed below the opening. The opening has a rectangular shape of large...
