DI System Shipping to Washington Chemical Plant

Shipping today is a two bed (cation ion exchange tank followed by an anion ion exchange tank) demineralizer for a chemical plant in Washington State. This unit is a DI60072 and will be used in parallel with several other older systems currently installed at the same plant to increase treated water capacity.

Condensate Polisher "Portfolio" Added

A sodium cycle condensate polisher "portfolio" page was added to the Res-Kem website.  As you have seen, I have used this blog to highlight the systems we have designed, manufactured and shipped to companies throughout North America.  Given the large number of systems we have manufactured, a consolidated list of these systems would be helpful rather than hunting through the blog. 

As you will see, Res-Kem has a base standard design that we have customized to meet the requirements of their facility or process.  Contact us if you want more information on a specific system you see or one you are contemplating.  I will add detailed information on each system in the coming weeks.  Also, I will continue to update this page with new systems we have sold.

Water Softener vs. Condensate Polisher – Knowing the Differences Can Help you "Get Greener"

Many companies are on a constant quest to run their business in the most energy-conscious, money-saving way possible. For those whose operations involve a low-pressure boiler system environment, investing in a condensate polisher is one of the easiest ways to “get greener” through energy efficiency and dollar savings.

In most every boiler plant, cold water softeners are used to treat boiler water makeup. What’s less common is the use of a condensate polisher which treats condensate return for resuse as boiler feedwater. There are several differences between a water softener and a condensate polisher. Let’s look at a few:

Water Softener vs. Condensate Polisher
Installion – a water softener is typically installed “upfront” with the boiler system in order to meet the ASME/manufacturer’s water quality specifications. A condensate polisher is often an “add-on” to an existing boiler system once steam traps, condensate piping, and condensate receivers age and form deposits (such as iron, copper, and magnesium) that cause thermal resistance to drop.

Materials of construction – water softeners are constructed of epoxy coated tanks or poly-lined FRP tanks, with cast iron or PVC valves and black iron or PVC piping. Res-Kem’s standard condensate polisher systems are fabricated completely with stainless steel. This all stainless steel construction is the best material choice for safe operation over a long time.

Temperature & flow rate – condensate polishers are built to operate at a much higher temperature and flow rate. Where water softeners operate below 80 degrees F, polishers operate substantially above 120 degrees F. The higher temperature and flow rate allow a polisher to acts as both an ion exchange device AND filter, removing copper and iron oxides that cause scale buildup. This oxide removal is not possible with a water softener system, which act only as an ion exchange device with limited filtering capabilities.

Stainless steel surface preparation – condensate polishers are passivated. After fabrication, to further enhance the corrosion resistance of our stainless steel components, all of our welded stainless steel piping and tanks are passivated. This is an expensive, multi-step process which includes bead blasting and passivation, for the longest condensate polisher life.

So what do all these differences ultimately mean for a customer who invests in a condensate polisher?

1) Fuel savings – a condensate polisher saves fuel by allowing higher boilerwater cycles of concentration by reducing the Fe and Cu oxides that cause scale buildup. Fuel savings is also realized through the reuse of heat in the steam condensate.

2) Reduced chemical usage – because of the reduction of oxides and scale buildup in the steam loop, less investment is needed in internal boiler treatment chemicals that are used to remove buildup.

3) Longer and safer service life – a condensate polisher’s passivated, stainless steel construction ensures optimal operation for many years, with minimal routine maintenance. The typical life expectancy of a condensate polisher is 10-20 years.

Condensate Polisher Product Bulletin Updated

Res-Kem has updated the features list of our standard condensate polisher product line because we had important ones which we did not tell anyone about!

For example:
  • All of the welded stainless steel piping and tank components have always used the expensive and necessary bead blasting and passivation, for long condensate polisher system life
  • All our stainless steel piping is welded per ASME Section IX
  • All our laterals use wedge wire screeening

Also, one common option customers have asked for is to provide stainless steel headers.  For most multiple unit systems we have sold, we have provided the inlet, outlet, brine, sub-surface wash and drain headers.  We needed to add this information to the bulletin as well.
