What Are FFS and Are They Right for Your Plant?

Posted by John Powalisz on 3/16/20 8:00 AM

Organic cycle chemistry based on film-forming substances (FFS) is being considered more frequently as an alternative to conventional corrosion-treatment programs. Here’s what you need to know about using FFS to inhibit corrosion throughout the water and steam circuits of fossil and combined cycle/heat recovery steam generator plants.  It should be noted that a well controlled, traditional chemistry program is a heavily favored, first choice for most plants.

Ensure High-Quality Edible Oils with Automatic Sampling

Posted by John Powalisz on 3/9/20 8:00 AM

Extracting and refining seeds, legumes and sometimes the “fruit” into oils, such as olive, avocado and vegetable oils, can be complicated. Processed oils need to be consistent in color and taste, and free of impurities that could negatively affect its quality. Automatic sampling can help optimize sampling accuracy and repeatability in every step of the extraction process, while ensuring a safe and delicious final product.

How to Choose the Right SWAS Configuration for Your Plant

Posted by John Powalisz on 2/24/20 8:00 AM

The technical design specification is the first step in designing a steam and water analysis system (SWAS) that operates accurately, reliably and safely for your plant’s conditions. Understanding the different possible configurations when designing your SWAS can help you choose one that will maximize efficiency and output while protecting plant assets, operators and the environment.

The Smart Approach to Cycle Chemistry

Posted by John Powalisz on 9/23/19 8:03 AM

Cycle chemistry management is the best way to help prevent, recognize and minimize potentially devastating water chemistry events. Smart alarms assist in this by monitoring cycle chemistry, identifying chemistry events in real time and allowing chemists to take proper actions to correct conditions - preventing system damage and protecting assets.

Harness the Power of the IIoT in Your Plant

Posted by John Powalisz on 9/16/19 8:00 AM

It’s not a matter of if, but when your plant will incorporate the Industrial Internet of Things (IIoT) into its everyday operations. The IIoT is making manufacturing smarter and faster than ever before by attaching networked sensors and intelligent devices to equipment to gather data, store it wirelessly, and then use analytics and machine learning to take actions that will optimize operations.

Don’t Get Caught on the Dark Side of the Grey Market

Posted by John Powalisz on 4/22/19 8:00 AM

All food and beverages undergo some form of processing, and those processes need to follow a variety of local, national and international food safety regulations. Buying certified samplers from authorized sellers is critical to ensuring your plant has the right sampling equipment to meet these standards and keep our food supply safe.

Yet many plants purchase sampling equipment outside manufacturers’ authorized distribution channels – also known as the grey market. According to the Harvard Business Review, an estimated $7 billion to $10 billion worth of products are sold every year in the United States outside these authorized channels. Most consumers and businesses buy items on the grey market because prices are generally lower.

But investing in these unauthorized products doesn’t give you the same peace of mind as those with genuine ones, and it could bring you back to square one both financially and in terms of inspection violations.

Will You Get the Alarm When it Matters Most?

Posted by John Powalisz on 4/8/19 8:00 AM

 

When chemistry alarms go off in your steam power plant, how do you know if it’s just a nuisance alarm or a real chemical event?

The fact is, most of the time, you don’t. For many plant operators, too many alarms can be worse than none at all. And that confusion can cost you time and money during a real event.

Troubleshooting alarms with manual processes can take hours or even days to find the issue – costing up to $100,000 for every hour your operation is down, or millions if permanent damage occurs. Alarm-related problems cost U.S. industry more than $20 billion a year, driving many plants to reduce alarms and meet the International Society of Automation (ISA) standard of 1 alarm every 10 minutes.

Representative Sampling from All-Purpose to Whole Wheat - Part 2

Posted by John Powalisz on 3/11/19 8:00 AM

Read Part I in this series to learn about the importance and impact of representative sampling.


Recent recalls of flour contaminated with salmonella and E. Coli have placed an increased focus on pathogen detection at milling operations.

Flour is considered a raw food product, since most flour products don’t undergo a heat treatment or kill process like ready-to-eat foods. Contaminated flour can make people sick if they eat under-cooked or uncooked flour-based foods, such as cookie dough or cake, muffin and bread mixes. 

It’s essential to implement a sampling process that provides a statistically significant sample for pathogen testing so you can quickly and accurately detect any contamination issues.

Whether you’re testing for pathogens or physical properties, samples should be statistically significant and represent the characteristics of the entire lot. The bottom line is that you want to divide an entire lot into small manageable units, then take a number of units regularly from the process. 

The samples should be taken from a place in the process where the material is well-mixed and won’t introduce bias (exclude different-sized particles or kill pathogens that might be present). The number of samples and sample mass collected should be related mathematically to the confidence level that is being targeted – for example, 95% confidence level requiring 60 samples of the lot.
