Hi Mr. Goutam, The Make-Up water control valve operates in the level in the Deaerator storage tank and thus to balance to the output the Make-up water flow rate has to adjust. This is exactly what I did and posted my corrected calculation spreadsheet in my response to Mr. Pierre above. Thanks...

Hi Mr. Pierre, I found that my adjusting the Make-Up water flow rate in ratio with Stripping Steam flow rate, I can get the Mass Balance corrected. I was able to do that. My updated spreadsheet is attached. My final values are as follows: 1. Make-Up water Flow Rate = 98.6 Tonne/hr 2...

Hi Mr. Goutam, I knew the Mass Balance at the Boiler is wrong and that was my question above. Hi Mr. Pierre, Yes I will download MEASUR today and look for the Deaerator example. The sketch is only a schematic, plus the Stripping steam is added on a side nozzle on the dome close to the bottom...

Hi All, Further to discussion on the below thread, I developed a calculation spreadsheet to perform some sizing calculations for a Pressurized Deaerator. https://www.eng-tips.com/threads/deaerator-sizing.521966/ I am however facing mass balance issues at the Boiler( please see the sketch...

There is an update from the client. They have decided not to connect the pumped condensate to the 2" Condensate header as they also think that there will too much back pressure on the traps to prevent them from delivering as per their capacities. Also they are sending the Condensate from the 2"...

Hi mk3223, If the trap discharge lines and the Condensate return header are sized for the low flash steam velocities of 15-20 m/sec and the traps are sized for the static head of 15m due to the riser will the traps still experience high back pressure causing them to fail or cause water hammer...

Hi katmar, Agree with you fully. I am yet to know the reason why they want to push the pumped condensate into the 2" Condensate return line which will already encounter significant pressure drop due to two phase flow. I also did not understand why would any one want the Condensate to Flash in...

Hi Mr. Goutam, There could be significant pipe length for the LP condensate and 2" condensate header before it reaches the Deaerator where the Condensate from IDOM traps will be allowed to separate from the Flash Steam. Thanks and Regards, Pavan Kumar

Hi George, Yes there is 15 m riser after the steam traps in IDOM area, so the traps would have to sized for the back pressure of 1.5 bar(g) at then minimum. The steam from the steam mains comes down by 15m to the heat exchange equipment and the condensate from these traps goes through the riser...

Thanks Mr. Pierre. I will download the Measur tool and start using it. Pavan

Dear All, I have a process problem that I am trying solve. The Condensate from one side of the plant is sent to Flash Tank, flash steam separated by venting to atmosphere and the LP condensate is pumped to DN 50 (2"NPS) Condensate Header that has Condensate Flash Steam. The question is will...

Hi mansari14, I agree that the critical Design parameters and details will not be shared by the vendor and the detailed design is done by the vendor in this case. I was doing these calculations for my self-learning purposes. I was only looking for the sizing requirements in terms of (1) Steam...

Hi FMJalink , I checked the normal operating and max operating pressures are 18 and 19 barg respectively. The DP is 25 barg. Pavan

Hi shvet, I agree but this requires a lot of documentation. I have had a chance to do this in the past. This is Greenfield project and I do not want to go this route. Can I use the Fire case scenario for vapor filled vessel to size the PSV to meet the code requirements as there is no other...

Hi All, I have to size a PSV located on the N2 buffer tank. The N2 buffer tank receives N2 from Air Separation plant at 19 bar(g). The vessel operates at 19 bar(g) at 34 Deg C. The vessel is designed per PED 2014/68/EU with a Design pressure of 25 bar(g) at 34 Deg C. The maximum pressure that...

Pavan Kumar (Chemical)(OP)3 Oct 24 20:26 Hi All, I am writing a report to share Knowledge about Design and Operation of Deaerators. I have gone through some very insightful threads in this forum on this topic such as the one shown below. I know there are two types of Deaerators (i) Spray Type...

Hi MJCronin, I wanted learn about Deaerator sizing for my upcoming project. Thanks and Regards, Pavan Kumar

I already did. Thanks. I did not get the answers I was looking for so I thought of re-posting the question here. Thanks again.

Hi All, I am trying to size a Deaerator for two electric boilers that we will be installed for a client. Can anyone provide me the references or documents that I can use to learn about Pressurized Deaerator sizing. I am looking for the basis for the following calculations: 1. Air venting...
