How can the heat from process condensate be recovered? Please give some advice!
Thread Content
Our company has process condensate at around 82 degrees, with a flow rate of 80 tons per hour. We’re not sure how to recover the heat contained in this water; discarding it directly would be a great waste. What is the most cost-effective way to handle this? Please help us come up with some ideas
A lithium bromide absorption heat pump can be used for cooling or heating water
There are specialized high-temperature condensate recovery processes. This is quite popular in its current form.
Currently, heat pump technology is a viable option; the condensation heat in chemical plants is substantial, accounting for about 60% of the total heat losses.
After treatments such as water treatment, it can be used as boiler feed water and then sent to the boiler to generate steam
The method on the 5th floor is good; alternatively, coils can be used to preheat the water for the boiler, and the cooled water can then be circulated using a circulation pump for use as cooling water in the process.
Could you explain in detail what the recycling process is?
Just do a simple setup and sell it directly to the bathroom for bathing: lol
Our company’s power plant refuses to accept it; they are worried that any problems with water treatment could lead to serious issues.
Could it be flashed to recover the heat value contained within, and then the water could be used in the boiler feed as part of the process water for absorption purposes?
Places where cooling capacity is generated using lithium bromide chiller units for temperature reduction
If there is a boiler, it can be used to preheat the air supplied to the boiler.
It is not practical to directly use process condensate at around 82 degrees to generate steam through heat exchange. If flash evaporation requires a pressure difference, it consumes some compression work, and it is necessary to conduct a comparative analysis to determine whether flash evaporation is economical. It can be used for configuring bathing water, but industrial water and domestic water cannot be connected to each other, as this can lead to accidents and is not worth the risk. The condensate from the reboilers and heat-tracing pipes in our plant’s tower is collected and sent to a condensate recovery unit (purchased from Liaoning Lengre). I work in construction; I’m not quite sure what the temperature of the condensate is.
Could you please explain in detail what kind of condensate recovery device is being used?
Can it be used for heating by circulating warm water in winter?
If there are oil fields in the vicinity, with many oil wells that require maintenance work on a daily basis, hot water is needed for melting wax in these wells, and steamers are required to clean the oil pipes during well repair. If an agreement can be reached with the oil fields, this hot water will have a proper use whether in summer or winter.
In Sinopec-owned enterprises, this condensate is generally used in winter to supply hot water for heating in residential areas, while in summer heat pumps utilize the energy contained in it for cooling, thereby compensating for the insufficient cooling capacity of the cooling units during that season.
If it’s not possible to return to the power plant, then lithium bromide can be used as a heat source to cool the chilled water; there are already many posts discussing this on the forum: http://bbs.hcbbs.com/thread-147380-1-1.html http://bbs.hcbbs.com/thread-98502-1-1.html
Set up a bathhouse in the factory so that people can take baths after work
Places where lithium bromide chillers are used in summer to generate cooling capacity for temperature reduction； Use it in places for heating in winter!
The boilers currently use soft water; a spiral plate heat exchanger is used to exchange heat between the soft water and the process condensate, with the soft water being returned to the boiler and the condensate being reused. If the temperature of the condensate water still doesn’t meet the requirements, another water cooling rack can be added to further lower the temperature; I think that’s possible. Otherwise, the only option would be to use a lithium-nickel alloy refrigerator, but that would likely require a larger investment. Hehe, just for your reference
