Could the recovery of the lean steam emitted from the deaerator top be considered as a way to save energy and reduce consumption? How do your respective devices work?
A stream of desalinated water is mixed with lean gas for contact, thereby absorbing the remaining heat; this mixture is then pressurized by a pump and combined with the feed to the deaeration tank. The specific energy consumption has not been calculated in detail, and it is not clear what the difference is between the heat recovered and the energy consumed by the pumps
The steam discharge from the deaerator is necessary; it also has certain pressure limits, and it is generally not feasible to recover it.
Some companies are currently promoting this project, but the return on investment is too low to be worthwhile.
It’s what’s known as waste steam recovery; many facilities have already implemented this system, but the specific benefits are not entirely clear
Waste steam can be recovered; the specific benefits depend on the conditions of the installation
There are specialized companies that deal with the recovery of such waste steam; for example, Wuhan Collin Environmental Protection Company is one I’m aware of
Consider the value of recovery. Although the operating requirements for this deaerator are not very stringent, recovery cannot alter the existing operating conditions; otherwise, the deoxygenated water will not meet the required standards, which would be counterproductive
