415 MW Combined Cycle Plant – South Korea

The Client's Needs

Daegu Metropolitain City
Daegu Metropolitain City, South Korea -- The Client is the South Korean company Lotte Engineering and Construction (Lotte E&C)...

South Korea, and especially the region around Daegu Metropolitan City, is currently experiencing a high level of economic growth. More and more power generation units are being built at existing power plant sites in cities throughout Korea in order to satisfy the growing demand for electricity.
In order to supply households in the region with district heat, Siemens has been awarded the complete design, assembly supervision and commissioning of a combined-cycle plant. The natural-gas-fired plant will achieve a gross installed electrical capacity of 415 megawatts.
Veolia has been contracted by Siemens for the delivery of a condensate polishing plant.


The Solution

Veolia supplied treatment lines for 2x50% of the total condensate flow. The capacity is 2x198 m³/hr of condensate using mixed beds in the hydrogen form with external regeneration via SeparIX®.
  • Cartridge Filter 2 x 198 m³/h
  • Mixed bed exchanger 2x 198 m³/h
  • External regeneration station (design for high purity condensate treatment, e.g. needed in ammonia cycle)
  • Chemical storage
  • Effluent receiving tank with transfers pumps

Process Description SeparIX®

Daegu SeparIX

The exhausted resins are transferred from the service mixed bed vessel to a regeneration and separation vessel, where the resins are regenerated first and then separated. This allows to remove the potentially contaminated interface resin and isolate it in a temporary storage vessel until the next batch is regenerated.
