Actually gas solubility of water decreases with increase in temperature and with decrease in pressure. In deaerator we used both properties. We increase DM water temperature and its temperature can be increased upto saturation temperature only. Above that it will convert into steam and will come out from vent. So heating is done slightly below saturation temperature. And rest of the job done by reducing partial pressure of gases.
Again great content sir. Please make video on compressor working (including thermodynamics behind it) on Industry perspective. It will be great help for us.
Sir .. deareator should also work on daltons law because sum of partial pressure is equal to total pressure.. as you told that we are adding steam which will reduce the partial pressure of non condensable gasses. And total pressure we can keep constant
Sir can you made long video on compressor bcz it,s good topic for chemical aspirants and itzs all competitions exam ask questions for this topic if you have time make a video thank you sir
Sir, I was studying in chemical engineering in (HALDIA INSTITUTE OF TECHNOLOGY) it was nearby haldia IOCL, so can I meet to you. Currently I'm pursuing 3rd year, sir please give me advice for gate exam, 🙏🙏🙏
Yesterday one more student from HIT was asking about GATE Exam. You may arrange one Guest lecture or seminar type of thing in your college where I can discuss with all of you at once regarding GATE exam.
Sir mai kanpur fertiliser me ammonia plant me kaam karta hu aur barauni se apprentice hu per waha dearotor ka hight jyada tha but yaha per ammonia plant me dearotor ka hight bahut kaam hai
Some of feed water get converted into vapour when heated by steam, which may cause vapour to escape through vent to atmosphere , then this will decrease feed water and increase make up water , but that doesn't happen, why?
Actually whatever steam we are adding for stripping action. Some of that steam pass through vent and some part get condensed. So, water quantity won’t decreased
In startup initial heating steam line is provided in Feed Storage Tank....Can this heating(say till 104C) is sufficient to remove 02 effectively? or heating through deaerator tank is must,???
Heating through deaerator gives better contact between steam and DM water. This is required for stripping action. We are using both heating and stripping in deaerator.
@@SandeepAcademy9 yes but which is efficient O2 removal ....1. heating in deaerator tank (vertical tank) or 2. feed storage tank. Stripping action is only in vertical tank right? . .Please reply to my mail sir

how partial pressure of gas maintained with respect to temperature sir
Very helpful! Thanks!
Thanks a lot !

Respected sir
The way you are explained is just wooow.
Thank u so much sir.
Sir please make vedio on compressor ... MCL bcl and it's working and thermodynamics ... It is very difficult yet very important topic for interviews.
Wow...sir...such a nice explanation...thank you so much 😊
Thank you, you have cleared my doubt why to keep this much heavy equipment at that much height!
Again great content sir. Please make video on compressor working (including thermodynamics behind it) on Industry perspective. It will be great help for us.
Great explanation sir 🙏

When I was doing apprenticeship in Andhra Sugars Ltd. I saw this deaerator.
Nice video sir....thank you a lot
Thank you for the vedio...Please make video on refinery flare system... 🙏 And m.s blending..
Regarding MS blending watch my video...How petrol is made
Thank you sir ...for the reply 🙏..one more request sir..if possible a vedio on refinery tank farm please...it would be a great help.. thank you. 🙏
Sir can you made long video on compressor bcz it,s good topic for chemical aspirants and itzs all competitions exam ask questions for this topic if you have time make a video thank you sir
Well explained. Can we recover heat of exhaust steam from deaerator?
So Condensate temperature also contributes to increased the bfw temperature.....
Pls make video Weak nitric acid oswald process plant
Sir please make a video on compressor and turbine it seems a very difficult
sir pressure is maintained by supply steam or water temperature...?
Sir please tell what's different bw tank and vessel.
Nice sir
sir... How steam is going when steam supply pressure and pressure in dea are equal...?
Steam supply pressure will be high
Sir please a lacture on steam drum BG boiler working🙏🙏
Sir, can u please summerize the requirement of API610 for centrifugal pump

Apki video dekh ke padhane ki jarurat nahi ❤
Sir mai kanpur fertiliser me ammonia plant me kaam karta hu aur barauni se apprentice hu per waha dearotor ka hight jyada tha but yaha per ammonia plant me dearotor ka hight bahut kaam hai
It all depends upon NPSH required of BFW pump. NPSH available must be greater than required. Check out my NPSH video.
