How is the condensate water from the vapor seal condenser of a back-pressure centrifugal compressor utilized? This condensate is water formed by the condensation of steam at 3.43 MPa after it has done work in a turbine, resulting in steam at 1.0 MPa. It is at atmospheric pressure; after being extracted by a steam extractor at the bottom of the turbine, it is directly discharged into the drain. The flow rate is 3–4 tons per hour, and the temperature ranges from 30 to 40°C. I wonder if any of you have any good suggestions regarding the recycling of this water?
It can be delivered to the water production station; the condensate seems to be pre-oxidized water plus a refined mixture.
Back-pressure turbines discharge their steam to a network at 1.0 MPa, and this does not result in large amounts of condensate water. What is drawn out from the bottom of such turbines is steam used for sealing purposes; the water that condenses after passing through a condenser can be sent back to a condensate recovery system or an deaerator for reuse.
There can’t be that much volume; it’s after all steam used for turbines, and its quality is quite high. This quantity can be recycled to the deaerator; when the pressure is low, it can be sent to the wet air cooler for use as deionized water
