Industrial Boiler Feed Water For Steam

Posted by Anthony DeLoach, President on Jul 31, 2018 10:01:00 AM

Industrial Boiler feed water in water treatment.

In the USA market alone it is estimated the manufacturing industry consumes over 400 millions of gallons per day (MGD) of water to produce steam. Approximately 60 millions of gallons per day (MGD) of water is sent to the blow down drains in manufacturing. Another approximate 300 millions of gallons per day (MGD) of steam is consumed for direct injection. All this steam required in manufacturing shares the same common need, “water”. But not only water but “purified and treated” water is needed. For without the treatment process US manufacturers would face constant shut downs and increased capital spending driving their cost of goods through the roof. One form of water treatment to protect boilers is degasification and deaeration.

Degasification towers remove

hydrogen sulfide (H2S) and carbon dioxide (CO2), and quite often dissolved oxygen (DO). Removing dissolved corrosive gases is critical to the life and efficiency of the boiler and if the gases remain in the boiler feed water such as carbon dioxide (CO2) it will create a recipe for disaster, higher operating cost, and a reduced life for the boiler system. The carbon dioxide (CO2) will convert into carbonic acid and form a corrosive condition for the boiler and other critical components. If a boiler system is operating an ion exchange process prior to the boiler the regeneration cost will increase dramatically because the resins will be consumed by the carbon dioxide (CO2). In addition to preserving and increasing the life of the resin the removal of the carbon dioxide (CO2) will elevate the pH of the water without the addition of other chemicals again lowering the operating cost of the system.

Renewable Energy for Water Treatment

Posted by Anthony DeLoach, President on Jul 10, 2018 8:50:00 AM

One of the largest consumers of energy in the US are the water and wastewater treatment plants.

Because of the need for large horsepower pumps and blowers a municipal water and wastewater treatment plant consumes a tremendous amount of kilowatt hours of electricity. The cost of the energy is factored into the “cost of production” of the treatment of water or wastewater and the “rate base” charge is increase accordingly to the consumer.

Does Renewable Power Work in a Water Treatment Plant?

Because solar energy is “space intensive” you do not see a lot of solar power being deployed across the USA at water treatment plants. This is in our opinion a mistake and most likely the decision was made back when solar power output was much lower. Now with increased efficiency of the solar panels and a decrease in production cost it makes tremendous sense to revisit the use of Solar energy for offsetting the operational cost of a water treatment plant or wastewater treatment plant operation.

Providing solar energy for specific pieces of process equipment is also a viable option when you consider deploying solar energy. As an example, to operate a Degasification tower or Decarbonator utilizing 10 350 watt solar panels will generate 3500 watts during peak day light hours and enough to offset the cost of smaller horsepower blower motors. If the solar panels are configured as a canopy they can also provide a nice shade or protection barrier above the piece of equipment if installed outdoors as most packed column towers are located outside.

What about other forms of renewable energy do they work?

At water treatment or wastewater treatment facilities? The use of Co-generation has been around for many years at Wastewater plant facilities waste water treatment plant. A cogeneration unit is a combination “Generator” to produce power and a “Thermal” energy source to produce heated water. The water can be used domestically or can be used to produce chilled water with the help of a Chiller system. The waste water treatment plant  provides a critical component by producing gases such as “Methane” which can be utilized as a fuel source for the cogeneration unit. Water treatment plants do not produce methane gases or other combustible forms of gases so you normally do not see Co-generation units deployed at a Water treatment facility.

Saving Steam With Degasification

Posted by Anthony DeLoach, President on Jun 5, 2018 12:00:00 AM

At most, business operations that utilize steam there is an awareness of both the potential short supply as well as the ongoing operating cost to produce the steam. Steam is utilized from simple task of heating buildings and pipes to more complex operations like distillation for use with the food and beverage markets or pharmaceutical industry. Oil refineries desperately depend on steam and is part of their key foundation of their operation.

When designing a system it helps to reduce the need for steam whenever possible, by selecting water treatment processes that are not dependent on steam such as a “Decarbonator”.
