Understanding the Challenges in HRSG Water and Steam Monitoring

Posted by John Powalisz on 7/12/22 2:01 PM

Many large industrial facilities, including refineries, chemical plants, and petrochemical facilities, are utilizing combined cycle units with heat recovery steam generators (HRSGs) to produce power for their operations. However, as many HRSGs operate at high temperatures and pressures, harsh conditions can transform seemingly minor chemistry upsets into major problems.

The Advantages of Chlorine Dosing to Control Biofilm

Posted by John Powalisz on 5/19/22 8:00 AM

Microorganisms such as bacteria, fungi, and algae can present challenges in maintaining and operating industrial cooling systems. These contaminants can increase pathogens and create biofilms in cooling systems. This biofilm can lead to equipment damage and inaccurate measurements. One way to combat these concerns is through chlorine dosing.

Five Questions to Ask When Selecting a Bulk Solids Sampler

Posted by John Powalisz on 3/24/22 8:00 AM

Let’s say you have a large order for a dry powdered food product. You need to be sure the product fits the customer’s specifications before it’s shipped, or you need to keep tabs on the moisture content of your material throughout a processing run, or you need to ensure that your chemical material doesn’t rise above a certain level of volatility. To accomplish these tasks, you’ll need to accurately sample and test the material using a sampler that can enter the material stream, capture a statistically significant quantity of that material that is representative of the process. For the most accurate and repeatable sampling, you will need to employ a method that limits bias and allows precise samples to be taken at regular intervals, leaving no room for error – an automatic sampler.

Maximizing Cycle Chemistry with Smart Analyzer Alarms

Posted by John Powalisz on 3/9/22 8:15 AM

In a steam and water analysis system (SWAS), alarms can frequently turn into a nuisance for operations and maintenance personnel. Over time, plant personnel can become desensitized, leading them to distrust analyzer data or not act when chemistry events arise. This can leave a power plant vulnerable to chemistry-related failures that could cause downtime and negatively impact production. Smart alarms help address these issues by monitoring cycle chemistry, identifying chemistry events in real-time, and allowing chemists to take proper actions to correct conditions. These smart analyzer alarms help steam and water operators improve their response time to critical chemistry events.

The Importance of Industrial Boiler Water Treatment

Posted by John Powalisz on 2/1/21 8:00 AM

Industrial steam plants and combined steam and power facilities, also known as cogeneration plants, commonly use boilers to provide high-quality steam and electric power. As the heart of the plant, these boilers are crucial to efficient energy creation. If impurities enter the boiler feedwater or corrosion develops inside the boiler, equipment can be damaged, the plant can experience unexpected downtime, and energy creation can be extremely ineffective. It’s critical to limit impurities and corrosion in a boiler system to maximize boiler output and prevent these challenges.
