۱۴ Days To Disinfect Cooling Towers In Nyc Or it Is A Misdemeanor!

home decorThese days it seems that operating budgets are being constantly challenged, scrutinized and dissected almost every season. Many facility managers are being asked to justify their operating budgets on a bi-yearly or quarterly basis. As a top water treatment company in NJ, we are often constantly asked to figure out ways to help our customers reduce their operating costs. Managers are often under pressure to identify areas in their budgets that can be slashed; at some point the topic of cutting the water treatment budget comes up.

So can you cut down or eliminate some of your boiler water treatment chemicals and still expect good results? If using the correct amount of boiler chemicals protects the boiler, won?t feeding a little less boiler chemical still be ok? It can’t be that bad, right?

Well, not exactly. When it comes to industrial water treatment chemistry, there is very little ambiguity. Every boiler chemical that is fed to a steam system is fed for Organophosphine Chelating agen an explicit reason. The following is a list of the major chemical components to a typical steam boiler treatment program, what each chemical is designed to do and what could happen if you under feed them.

Oxygen Scavenger

Oxygen scavengers are chemicals that are fed to consume any remaining oxygen that did not get eliminated from mechanical deaeration of the feed water. Sufficient feed of these chemicals is essential in order to consume the oxygen in the feed water before it can cause oxygen pitting corrosion in the feed water and boiler systems. Sulfite is measured as a residual (or what has not been consumed by the oxygen removal process) in the boiler. In many systems, most of the sulfite fed is what is used to build the residual level that you can accurately test for. In other systems where the mechanical deaeration is less than desirable, a great portion of the chemical fed is used to eliminate the oxygen and only a small percentage is used to build the residual which is measured in the boiler.

Typically, for a well-run boiler system with good mechanical deaeration, the goal of oxygen scavenger feeding is to have at least 1 PPM (parts per million) residual per cycle of concentration in the boiler or at least 30 PPM, which ever number is greater. This calculation certifies (at least mathematically) that there is at least 1 PPM of sulfite residual at all times in the feed water. This ensures that your feed water system is protected and the transfer of iron to the boiler (as a byproduct of the corrosion process) is minimal.

So, reducing oxygen scavenger feed jeopardizes the protection of the feed water system. If you are running a polymer program, this transfer of iron to the boiler system will then INCREASE the polymer demand in the boiler!

Scale and Deposit Control Chemicals

The most widely used internal treatment chemistries that are used to control scale deposition in boilers. They are nitrites, phosphates and polymers. Inadequate feeding of internal treatment chemistry (polymer) can result in both iron and calcium deposition on the heat exchange surfaces. This scale will impede heat transfer and will increase your fuel costs. Scale is also very detrimental to the projected lifespan of the heat exchange equipment. Scale does not form uniformly and, as a result, stress caused by temperature extremes will accumulate between the insulated (from scale) portions and the clean portions. This process can quickly fatigue system metal and ultimately cause system failure.

Alkalinity Booster

Proper alkalinity is needed to create the optimal environment for both polymer and orthophosphate boiler programs to work properly. Alkalinity Booster is needed for the proper precipitation and dispersion of hardness ions. It reacts with the scale and deposit control chemical and calcium in the water to create a soft calcium precipitate sludge that will eventually be eliminated through boiler blowdown.

Inadequate pH (alkalinity) in the feed water will result in corrosion of the feed water system and ultimately transport the iron byproducts of corrosion to the boiler which increases the polymer demand.

Neutralizing Amines

Neutralizing amines are fed to increase the pH of the returning condensate to between 8.3 and 9.0. Without amine feed, the pH of condensate is normally driven downwards during steam production due to the formation of carbonic acid in the condensate due to the breakdown of alkalinity in the boiler water. Neutralizing amines counteract the acidity due to the formation of carbonic acid. Under feeding amines will result in increased corrosion rates, and ultimately the transfer of iron byproducts of corrosion back to the boiler which (you guessed it) increases polymer demand.

Summary

In general, if overfeeding boiler treatment chemicals causes issues with carryover, then underfeeding boiler treatment chemicals causes issues with scale and corrosion. Cutting back on water treatment chemistry is often pennywise and pound foolish. An appropriate water treatment program will benefit the performance and efficiency of any boiler system, but in a steam boiler system it is even more serious. Problems in a steam boiler system that are caused by underfeeding boiler chemicals can escalate very quickly, and if no corrective measures are taken, these issues can lead to long interruptions of service and expensive repairs.

Under feeding boiler chemicals in a steam system can eventually lead to boiler tube failure. In the case of a rupture under pressure, consequences could be catastrophic. For these reasons, always be sure to consult with your boiler system manufacturer and get the advice of a reputable water treatment company before making any changes.

The takeaway here should be obvious: When considering your boiler water treatment budget, saving pennies today could wind up costing big dollars down the road.

Environmentally Friendly Cooling Tower Water Treatment Chemicals?

Taking charge: Researchers team up to make better batteries Assistant Professor Jose Mendoza-Cortes and postdoctoral researcher A. Nijamudheen teamed with researchers from Cornell to design a more efficient battery. Credit: Florida State University

Antiscalant 2-phosphonobutane-1,2,4-tricarboxylic Acid ...A Florida State University and Cornell University research team found that batteries built from inexpensive and safe components can deliver three to four times the punch of batteries built with today’s state-of-the-art lithium ion technology.

The researchers’ work is published today in Nature Communications.

A. Nijamudheen, a postdoctoral researcher at the FAMU-FSU College of Engineering, and Snehashis Choudhury, a doctoral student at Cornell University, along with faculty members at both institutions embarked on an ambitious investigation into what hampers current battery design and how to improve it.

“If one looks at the cost of batteries over time, it is unsurprising to see that the vector is consistently pointed upward,” Choudhury said. “Broad-based adoption of technologies that require batteries demand lower costs.”

With the hope of bringing those costs down, researchers tackled a few specific problems related to electrolytes, a critical part of a battery’s construction that promotes the movement of ions from one electrode to the other.

The teams set out to understand the chemical pathways by which electrolytes degraded at the battery electrodes. The researchers not only identified the mechanisms for how the electrolytes degrade, they also discovered multiple strategies to remedy the problem.

“We discovered that controlling the ionic properties of the interphases formed at the negative electrode is the key,” Nijamudheen said.

Using quantum calculations, Nijamudheen and his adviser, FAMU-FSU Assistant Professor of Chemical Engineering Jose Mendoza-Cortes, found that the problem stems from the way a component of the electrolytes called diglyme undergoes polymerization. Polymerization is a process where molecules combine chemically to produce a long chain-like molecule called a polymer.

In the case of batteries, electrolytes often break apart and re-form to create much larger molecules after prolonged contact with both the negative and positive electrodes of a battery.

“While the degradation process itself is harmless, its byproducts block ions from accessing the battery electrodes, which over time reduces the amount of stored energy than can be recovered from a battery,” said Lynden Archer, a Cornell University professor and Choudhury’s adviser.

However, while some types of polymers that result from this process would block ions from reaching the electrodes, others have been proven effective in prolonging battery life.

With their polymerization calculations in hand, the researchers began investigating other types of electrolytes where the polymerization process wouldn’t impede the battery’s performance.

Typically, lithium batteries are made with organic carbonate electrolytes, but these electrolytes are highly flammable. Expensive thermal regulation infrastructure that provides cooling of overheated battery cells is therefore mandatory for Organophosphine Chelating agen reducing risks for thermal runaway and battery fires.

The researchers instead tested a lithium-nitrate electrolyte, a stable electrolyte that wasn’t flammable.

Using that electrolyte, the researchers began running experiments on the solid electrolyte interphase or SEI. The SEI is a protective layer formed on the negative electrode as a result of electrolyte decomposition, usually during a battery’s first cycle.

“Once you have a good SEI, you have a good battery,” said Mendoza-Cortes, who is also an assistant professor at the FAMU-FSU College of Engineering. “The idea is to find an electrolyte and solvent that can form an SEI that can be stable and plays in your favor.”

The researchers engineered a new type of SEI that forms spontaneously in a battery cell using sacrificial salt or molecular species introduced via the electrolytes. They also introduced chain transfer agents?a string of molecules?that interacted with the diglyme to form a shield that protects the negatively charged electrode from degrading.

To evaluate the effectiveness of the design, the research team performed a series of experiments on the battery’s ability to be used and then recharged. They found it could go through about 2,000 cycles, well above the conventional 300 to 500 charge cycles associated with most lithium-ion batteries.

“With this process, we could get an efficiency that is unprecedented for this kind of system,” Mendoza-Cortes said. “The bottom line is we improved the SEI. That would mean more power that lasts longer. There is much potential there.”

Avoiding air-duct And Vent Cleaning Is Bad For Business: Part One

Chelating agents are useful and at times controversial chemicals that are used in large quantities. They can bind heavy metals in food, for example, or prevent lime to deposit from washing water. Chelating agents are used above all in detergents and cleaners to lower water hardness, but also for industrial applications, food processing and medicine. The market research institute Ceresana expects worldwide demand for chelating agents to rise to more than 4.34 million tonnes by 2022.

Main Application Washing Powder

The most important sales market for chelating agents are washing powders. They constituted about 60% of total demand in 2014. Chelating agents are not only used in household detergents and cleaners, but also in industrial applications. They are applied, among others, in the pulp and paper industry, textiles and leather, the food industry, medicine and cosmetics. The pulp industry was the largest consumer in 2014 with a volume of about 150.000 tonnes. In this sector, chelating agents are used for manufacturing bleached chemical pulp and for de-inking recycled waste paper.

Alternatives to Phosphates Wanted

While demand for chelating agents rises strongly in emerging countries, saturated markets in Western Europe and North America will only grow slightly over the next years. They are characterized by product substitution. Environmental concerns are having an impact on the use of the controversial sodium tripolyphosphate (STPP) in the European Union as well as in Canada and the USA. Many manufacturers are voluntarily refraining from applying STPP. Governmental prohibitions and limitations are becoming more and more effective as well. In Europe, demand for STPP in household washing powders has already fallen significantly. Over the next years, this trend is expected to lead to a clear volume decline of STPP for dishwashing detergents.

Growth Market for Environmentally Friendly Chelating Agents

There is an increasing desire for replacing conventional chelating agents such as STPP, phosphonates, EDTA, NTA or DTPA in an environmentally friendly way. Biodegradability is most important in order to prevent long-term consequences for humans and the environment. Citric acid, GLDA, MGDA, EDDS, IDS, gluconic acid, and glucoheptonates are to be more environmentally friendly. Ceresana expects its demand to rise by 2.4% p.a. worldwide.
