Chilled Water operated Alkaline Loop
A chiller cools the cooling water down near to 0 °C and then feeds
it to the mixing condensers. This means that condensation can take
place at a reduced pressure. Only one booster stage is required to
effect compression up to the main condenser. Polluted cooling water
cycles around in a closed loop system and is cooled down in the brine-cooled plate heat exchangers.
Caustic soda is added to the circuit water to prevent contamination by
fatty deposits in the plate heat exchangers. Condensate from the motive and suction steam is discharged together
with impurities rising from the process via a special fat separator.
The advantages of such a system are:
- Low energy requirements
- Clean cooling water
- Low maintenance costs
- Minimum amount of waste water
