Condensate recovery related
Thread Content
To recycle 70 t/h of air-conditioning condensate and process condensate at 0.5 MPa, it is necessary to remove iron from them before sending them to the deaerator for further use. Is flash evaporation still needed for recycling? Is it sufficient to use a buffer tank? If flash evaporation is to be used, how should it be calculated? What is the outlet pressure of the flash evaporation tank, and will steam be generated for subsequent treatment? I asked several companies, and all said they couldn’t build a flash tank with such a large capacity. .
The temperature is too high; many manufacturers are unable to operate under such conditions. By lowering the temperature, flash evaporation is not necessary, and recovery is possible
So how do you lower the temperature? If the pressure drops after no flashing, will steam come out?
Air cooling, water cooling – there’s no really good solution at the moment. The recovered demineralized water is more valuable than the circulating water used for cooling
Can it be sent to a buffer tank or buffer water tank to reduce the pressure to atmospheric level, so that the temperature can also drop? The purpose is to recycle the condensed water after iron removal.
It can go into a buffer tank, which can reduce pressure; the temperature doesn’t drop
Oh, once the pressure is reduced to room temperature and further processing begins, there will be no steam left. Isn’t the maximum temperature at atmospheric pressure 100 degrees?
Well, the maximum temperature is 100°C. At such high temperatures, there is no technology available in China for recovering condensed water; it’s only possible to recover it when the temperature is reduced to around 50°C. (PS: The best company in China for condensed water recovery is Beijing Tuofeng – this isn’t an advertisement.)
Oh, thanks. Answered so many
There aren’t many technologies for recovering high-temperature condensate water; just search for steam condensate recovery on Baidu – there are many manufacturers available, so consult them directly!
