Sparger Test program " was conducted by KAERI (Korea Atomic Energy Research Institute) for the SKN34 IRWST and sparger design. [Ref. 1, Ref. 2 and ]) b. The methodology for determining the pressure on the walls and floor is used for APR1400 the same as the System 80+.[Ref. 5]
Summary. The impact of bioreactor and sparger scaleup on gas transfer properties was investigated using four geometrically similar bioreactors ranging in size from 15L to 2500L total volume with the same sintered metal frit (microporous) sparger design.
A simplified design procedure is presented which allows engineers to accurately maintain a given pressure and flow at the entrance to the sparger. The design provides for uniform flow across the cooling tower basin, and prevents an increase in back pressure or open channel flow within the sparger, minimizing the effect on upstream performance.
could be achieved with the sparger design obtained with the scaling. The results of these simulations were also used to determine the location of the instrumentation and to design a test matrix. The final design of the sparger used during the PPOOLEX experiments can be found in (Laine et al., 2015; GallegoMarcos et al., 2015).
Nov 25, 2008· The design is really only critical at start up when the column contents are cold. If you do not break the steam flow up into small individual streams by using a sparger with holes of around 3 or 4 mm you will get hammer and vibration when the steam hits the cold liquid. Even with a sparger you will want to start up gently.

Additionally, Shell Catalyst Technologies' sulphur degasser can be retrofitted into an existing pit or placed into a separate vessel entirely. This reduces implementation time and cost and is a result of its simple design. The simplicity of design is a common theme across our gas processing offerings.

An example from today's design methodologies would be to contrast allowable design in concrete to ultimate strength. Allowable design gives sizing and reinforcing solutions which do not require the cumbersome additional checks for deflections. Simplified seismic design procedures would benefit from a similar overall approach.
The K factor formula for fire protection . When we start any hydraulic calculation for a water based fire protection systems such as a fire sprinklers, water mist systems the kfactor formula is the first which we will need to use and as it is so fundamental all fire protection engineers must have a .

In Fig. 3 it is shown, that the newer design of the Advanced BUSS Loop® reactor achieves higher mixing and gassing rates to the reaction vessel by using a reaction pump that is able to circulate liquids with a high gas load (up to 30 vol. %) which also enhance even more the mass transfer in the reaction vessel and external loop.
The design of perforated tube for achieving desired flow distribution, involves arriving at the size of the holes and its spacing along the length and circumference. In case of spargers introduced in Indian PHWRs, the design is validated by rigorous experimentation. For sparger tubes, the size and location of holes were arrived based
