Introduction The flow in the header of a finger-type slug catcher is analyzed using CFD techniques. In order to design a high-performance finger-type slug catcher, it is necessary that the fluid flow in the inlet header manifold is evenly distributed among the different fingers. Analysis A detailed flow analysis by
Combined Pressure Surge and Dynamic Stress Analysis Introduction At BASF Antwerp a steel pipeline was under construction, this pipeline was to be used for the offloading of naphtha from ships arriving at a jetty. The pipeline is 1.6 km long with several pipe bridges. The jetty contains Emergency Release Couplers
Pressure Surge Analysis Introduction An existing power plant of Essent will be extended with a new power plant. The new power plant is based on a Combined Cycle Unit (CCU) which includes the combination of a Gas Turbine with a Steam System. The surface condenser of the new power plant
Combined Pressure Surge and Dynamic Stress Analysis Introduction In the harbor of Antwerp an unloading line was being commissioned for use with cyclohexane. This line features two ship loading arms, located at the end of a jetty. From the loading arms, the unloading line runs towards two storage tanks. Transient
Pressure Surge Analysis Introduction An LNG-plant was planning to construct an additional LNG bunkering line that will be used to fuel ferry ships in Stavanger.
