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. Both a main and booster pump are used to achieve the flow through the 600-meter-long pipe line connecting to the ships through a loading arm,
Feasibility Study Introduction A cooling water system consists of a large underground branched GRP piping system connecting to steel branch continuations at each U/G-A/G interface. In the detailed design phase the fitness for purpose of the GRP part of the system will be demonstrated by the GRP supplier by means
Vibrations had been seen in the piping of a reciprocating compressor plant and the operator of the plant was worried that fatigue cracks could occur. Therefore a study was conducted by DRG to determine how the vibration levels could be reduced and whether they were leading to stress levels exceeding
Accumulators are used to reduce pressure pulsations from reciprocating pumps by adding volume to the piping. In the preliminary design stage the size and position of the accumulator needs to be determined before the piping design is completed. The performance of the system including the pump and connected piping is
Commercially available pulsation analysis software uses either a transient (time domain) or harmonic (frequency domain) solver. A time domain solver is more accurate for determining the pulsation amplitude, but solving in the frequency domain can be orders of magnitude faster. Which solver should you use and why is there a
When purchasing or delivering a reciprocating pump an API674 pulsation study might be required. The API 674 describes two different design approaches in Annex C (2010 edition). This post describes the most important differences between the design approaches and the pro’s and con’s between the two approaches. Regardless of the
