Prevent Sampling Errors with Secondary Cooling Systems

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

 

The goal of a steam and water analysis system (SWAS) in power generation is to properly condition the sample so that it is representative of the process. Secondary sample cooling provides a way to eliminate measurement uncertainty issues by removing the variable of temperature from the measurement. Secondary cooling also provides a temperature “cushion” when primary cooling systems are undersized or underperforming.

Why Should You Sample in Cogeneration Plants?

Posted by John Powalisz on 7/27/20 8:00 AM

Combined steam and power facilities, also known as cogeneration plants, use heat recovery steam generators or traditional boilers to provide both high-quality steam and electric power from one fuel source. With natural gas achieving about 30-40% efficiency for power only, creating and sampling your process steam enables combined cycle cogeneration plants to operate at efficiencies between 65-90%.

Match the Right Heat Exchanger to Your Application

Posted by John Powalisz on 7/20/20 8:00 AM

Many industrial processes require the addition or removal of heat and heat exchangers are often used to do this. There are many heat exchange applications within processing plants such a process heating and cooling, vapor condensing to sample conditioning. Ensure you are meeting your application needs by selecting the right specialty heat exchanger.

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.

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.
