Is it feasible to discharge medium-temperature and medium-pressure steam condensate directly?
Thread Content
Is it feasible to use only a steam trap assembly to discharge the 3.82MPA saturated steam condensate from the plant’s pipe racks into the drain? Are there any issues with the flashing of the condensed water that is discharged? Is it necessary to flash it before discharging it into the drain? Not recycled.
Condensate water from medium-temperature and medium-pressure steam cannot be discharged directly arbitrarily. Feasibility depends not on whether it “looks clean,” but on water quality data, the destination of discharges, and whether a discharge permit has been obtained. Under the current stricter environmental regulations, recycling is the mainstream and compliant choice.
It’s the utility tunnels within the factory; since the locations are quite scattered, the cost of recovery is somewhat high. It is discharged into the ditches within the factory; under normal operation, the amount of condensate water is relatively small. When the pressure and temperature are high, flash evaporation occurs during direct discharge.
