What is the purpose of condensate Polishing unit?

Condensate polishers are used to maintain a proper quality of water by removing impurities from return condensate. The decision to polish return condensate for re-use is purely economical. The condensate can be returned to an ultra pure state by simple polishing rather than using fresh make up process water.

What is condensate Polishing unit?

Condensate polishers are resin-based ion exchange systems that are commonly used in power plant condensate systems to remove dissolved contaminants (chlorides and silica) and suspended contaminants (iron or copper oxide particulates).

What is a polishing unit?

Fuel polishing units remove water and particulates from diesel fuel which is stored for the medium to long term. Over time, stored fuel for back up generators or on boats degrade and become infected with water from condensation.

How does a water polisher work?

The Water Polisher is an advanced stormwater treatment system utilizing an up flow media filter with built-in pretreatment. This patented design provides double-chambered separation to remove large to fine sediments and prevent clogging challenges found in downward flow media filters.

What is condensate in a power plant?

Condensate water is sprayed into the low pressure turbine exhaust hoods to condense the steam, reduce backpressure, and increase turbine exhaust steam velocity to reduce the exhaust hood temperature. A temperature element located in the exhaust hood of each low pressure turbine controls the spray valve.

What is diesel polishing?

Diesel fuel polishing is the process by which emulsified water is removed from diesel fuel in storage tanks in order to maintain the integrity of the fuel. However, the process used to remove sulfur from diesel affects the functionality of the fuel.

What is polishing in filtration?

Polishing is a high-stream filtering process where suspended solids and BOD are removed from wastewater. Polishing usually is the end phase in wastewater treatment process to make water more hygienic and environmentally safe for discharge into receiving waters.

What is condensate cycle?

The Condensate cycle includes the flow of water from Condenser to Deaerator. The equipments involved are Condenser, CEP (Condensate Extraction Pump), Gland steam cooler, LP heaters (Low Pressure Heaters). 2. The feed water cycle includes Deaerator, FST (Feed Storage Tank), Booster Pump, BFP (boiler Feed Pump).

Do you have to own a condensate polisher?

The customer owns the equipment and must have operators trained to operate/maintain the equipment, and handle backwash water and brine from resin regeneration. As with customer-owned condensate polishers, these 316 L SS sodium cycle condensate polishing systems are regenerated onsite.

What’s the difference between ion exchange and condensate polishing?

Condensate polishing is a proven method of producing high purity demineralized water from recovered boiler condensate. Condensate polishing differs from regular ion exchange in that ion exchange is only part of the overall process as the condensate is already of high quality and only requires polishing.

How does a deep bed condensate polisher work?

On-site external regeneration is the most common technique used today for deep-bed condensate polishers. The resin is sluiced out of the service vessel using water or water and air before being transferred to an on-site regeneration station.
