Efficiently Run Your SWAS with Program Best Practices

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

Effectively monitoring cycle chemistry in a power plant relies on the availability, accuracy and trustworthiness of analyzer data. Like most industrial monitoring systems, the quality of the data is governed by the full Steam and Water Analysis System (SWAS) with accurate, timely data for corrective action.

Steam and Water Management: Going Beyond Power Plant Processes

Posted by John Powalisz on 2/15/21 8:00 AM

High-quality steam is the key to safe and efficient production in processing plants including refineries, chemical facilities, pulp and paper production, food processing and co-generation plants. Improper chemistry control in the steam cycle can leave your plant at risk for buildup of impurities and corrosion of equipment, insufficient power production, and damages to the environment and plant personnel.

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.

Optimize Sample Cooler Temperatures for Ideal Results

Posted by John Powalisz on 11/30/20 8:00 AM

The thermal management of sample coolers is critical to the proper function of a steam and water analysis system (SWAS). Extreme temperatures can lead to erratic or unreliable data, equipment damage and unscheduled downtime. As the EPRI standard states, the goal of a sample system is to “transport and condition a sample without altering the characteristics of interest. The system parameters which need to be controlled are velocity, pressure and temperature.”

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.
