RMW,
any idea on how much efficiency for OTSG can be considered. I have burner capacity and also got the "Steam" book, I can calculate amount of steam generated from heat input considering the available heat transfer area of convection and radiant section. thanks
It is Once Through Steam Generator (OTSG), water tube.
I already have the surface area for the radiant and convection section. what could be the next step to calculate?
I am trying to understand the control exactly, there were modifications and don't know whether the drawing I have is...
Hi,
we have a steam generator (>30 year old) for which I need to determin the capacity in order to verify the PSV sizes and check its relief capacity for the existing steam generator for reduced rating (PSV set pressure) conditions (de-rating is required due to reduced tube thickness found in...
Hi there,
We are doing de-rating of a steam generator from current 1700 psig design pressure on steam side to 1300 psig due to the lower wall thickness found in the economiser and steam generator tubes during the insepction. This is very old plant and no documentation available on original...
I am doing project to do Finite element analysis in COMSOL for Amine absober packed column, I am not able to find dimensions of structured packing for modeling the geometry of packing in COMSOL, would any one please advise me how to build a geometry for structured packing? I have seached thro'...
Can any one suggest which property package is good for simulation (HYSYS/ProII/VMGSIM) of NH3 & CO2 dissolved in water. I need to do a simulation of a distillation column which separates NH3/CO2 from water. I think Peng Robinson or SRK are not good for this mixture.
thanks

There is a need of providing the flow switch at outlet of Rupture disk installation for liquid relief application to tank. 65 psig back pressure is created because of flow of liquid in another pipe where the RD will be discharging, which is 2000 ft long line going to tank.
Instrument asked me...
MAWP is 270 psig.
Tank is having pressure = 0 psig
65 psig back pressure is created because of flow of liquid in another pipe where the RD will be discharging, which is 2000 ft long line going to tank.
This is unusual but problem is client does not like to lay another pipeline of 2000 ft long...
I know that rupture pin valve can be used in place of rupture disk. But it requires an ASME certificate to use in my project(Client's requirement). Does anyone knows any vendor who can meet this requirement?
I am aware about surge protection devices used in pipe line like Dan Flo. This is not the Surge protection design.
The valve located at tank inlet will be made locked open.
Now there is change in design, instead of PSV there will be a control valve(Sur Flo) will be provided (Sur Flo type control...
I am in a process of sizing the PSV for Crude oil -Liquid relief. This PSV is to be located on a Crude pipe line located in Petro-Canada Edmonton Refinery. This PSV will use to protect some part of pipeline inside the refinery. In recent operation they observe some spike in Pressure up to 373...
