Condensate Polisher Shipped to New Jersey University

Last week, Res-Kem shipped a condensate polisher to a New Jersey university.  This condensate polisher will be installed as part of a new onsite power production facility at the university operated by an independent energy development company.  They will produce power for the university under a DBOM (Design, Build, Operate, Maintain) agreement. Excess power produced gets sold to the PJM.

Customer	An independent energy development company specializing in the development, engineering, construction, start up, commissioning, operation, maintenance and management, as well as, ownership of Central Energy Centers, Renewable Energy projects and Combined Heat, Chilling and Power  Production Facilities.
General water treatment application	Two large 48”X60” sodium cycle condensate polisher for removal of contaminants in the return condensate and the return condensate from the steam driven chillers on-site
Savings and/or ROI the customer wants to achieve	Fuel and chemical saving related to the removal of iron and calcium from the condensate streams and ultimately the boiler feedwater
Operating conditions	250 gpm max, 150 gpm continuous operating at 180F
System configuration	Twin parallel / Alternating system
Materials of construction	Skid mounted 304 SS pressure vessels Schedule 10 welded /flanged face piping
Type of valves and actuators	Bray valves with Bray actuators
System Control	Allen Bradley PLC operates the system as alternating or parallel
System schematic	Polisher collectively handles two condensate streams – return condensate from campus and condensate from steam driven chillers
Special Features	Sample cooler mounted on skid which can sample the inlet and outlet of each vessel Inlet and outlet headers between each system on skid

Amazing Craftsmanship of Condensate Polisher from Res-Kem

I need to acknowledge the excellent, American craftsmanship which goes into our condensate polishers!  It may be the engineer in me, because this is an amazing piece of work!  My kudos go to:

• Tony, our Lead Design Engineer who had to design the vessel, the vessel penetrations, pad flanges, internal clips and its internals with amazing accuracy (and I am certain a few sleepless nights!). 
• Shane, our Lead Assembly Person who had to go into this vessel and assemble Tony's creation, piece by piece day after day. 

This attention to detail is particularly admirable when it is likely no one will see ever see these distributors, header and laterals again! 

As we know, the things you cannot see separate the highest quality product from others.     



Condensate Polisher Internal Components in 316 L Stainless Steel from Res-Kem



 You are looking from the top of this photo to the bottom:

• Inlet distributor
• Brine Distributor
• Sub-surface was distributor
• Hub and Lateral underdrain

You have too realize everything you see takes place in a 54 inch diameter tank that is approximately 84 inches tall!  Shane had to squeeze through a 14 inch x 18 inch elliptical manway and Bill, who assisted Shane, had to give each piece to Shane through the same manway!
