Why Isn't Using Differential Pressure Acceptable For My Air Permit CAM?

Rolling averages, pounds per hour vs. grains per standard dry cubic foot, PM 10 vs. PM 2.5…the complexities of emissions control, monitoring and compliance can make facility personnel feel overwhelmed at times. Trying to navigate the murky combination of environmental regulations from Federal, State and Local authorities while also striving to hit production targets can pose a challenge. At times, this is further complicated by the fact that many plants do not possess state of the art pollution control equipment and must rely on legacy systems in order to achieve compliance.

What's the Difference Between Continuous Emissions Monitoring and Periodic Measurement?

Navigating the complexities of the current and future regulatory environment can pose quite a challenge to many facilities that fall under EPA air emissions standards for particulate matter (i.e. dust). One of the most complex parts of compliance involves monitoring of your pollution control devices. While installing a dust collection system is complicated enough, often times facilities get hung up on the monitoring and reporting side of things rather than on the technical aspects of their collector. 

One issue that comes up frequently for both new and existing plants is whether to conduct periodic monitoring or to implement a continuous emissions monitoring (CEM) system. As we will see the issue depends not only on the particular air permit for each plant but also on several practical factors. 

What Is Periodic Monitoring?

How to simplify emissions compliance reporting

Everyone's favorite job....NOT

Emissions regulations can seem daunting even just to begin reading. Many standards taking up over 100+ pages in addition to basic outlines established by Title V requirements. And it will come as no surprise to readers of this blog that some of the most onerous aspects of modern emissions regulation involve emissions compliance reporting. Non-compliance with these recording and reporting requirements frequently lead to fines in excess of those related to actual emissions excursions. 

But it's a lot of work, and dreadfully monotonous. So most folks look for ways to reduce the difficulty and complexity of compliance reporting, both to improve efficiency and avoid fines over incorrect reporting. Let’s looks at one way your plant can simplify its emissions compliance reporting. 

Use Triboelectric Monitoring as the Basis for Your CAM Plan

How to Use EPA Method 9 & Method 22 for visual emissions observation

Oldies....and not so goodies

Plume opacity emission standards and requirements have played a key role in enforcement of federal, state, and local air pollution regulations. Failure to take these regulations seriously can be costly, as violations of opacity limits for air permits can result in up to $25,000 per source per day!

For decades, the most common method used to monitor opacity levels has been the EPA method 9 and 22 visual observation tests. Consistent economical compliance relies on a better understanding of these tests, how they related to legacy air permits in the past ,and how they will relate going forward. 

What are Method 9 and Method 22?

If I monitor emissions continuously do I have to report the results?

Complying with a CEMS (continuous emissions monitoring system) mandate from the air quality board may seem like a daunting task for most plants. While many eventually install the CEMS few realize that the work does not stop there. Many plants find themselves in trouble not over a lack of the CEMS, but rather over failure to observe the reporting requirements that accompany it. 

What is a CEMS and why use one?New Call-to-action

The CEMS class of devices includes a wide range of different monitoring systems for different pollutants including acid gases like NOx, chlorine, HDIs and particulate matter, as well as other specific hazardous compounds such as heavy metals like lead and hex chrome. For our purposes, we will focus on PM CEMS used for monitoring particulate matter emissions such as what you find placed after a dust collector.

The Battle Between Triboelectic Dust Detection and Opacity Meters

Regulating authorities require nearly all industrial facilities to measure dust particulate emissions in some fashion. Opacity meters were, for decades, the standard required by the EPA and under many State and Local air permits.

However, in recent years, triboelectric particulate monitors have been promoted by some as superior to opacity meters, and have begun replacing opacity meters in many applications across all industries. So why the change? Is there a reason to switch to triboelectric monitoring devices for dust/particulate monitoring?

Which is better - an AC or DC triboelectric bag leak detection system?

What Does It All Mean

When considering a triboelectric bag leak detection system OEMs, sales reps, and other re-sellers may throw a number of seemingly confusing technical specs at the project engineer. One that frequently gets cited is whether the unit processes an AC signal or a DC signal. Often this is even touted as an advantage over other makes and models.  But not much explanation accompanies these claims as to the difference between the AC or DC signal, or why it even matters. So we often field questions from visitors to our site who have noted the various technical specifications of our units, as well as read much in our blog about our our Unified AC/DC signal processing technology.

But what is the difference between triboelectric systems that use AC and those that use DC? And what benefit does AC/DC unified technology provide? Lets take a look at the differences and highlight what one is used over the other. 

Superior Signal Vs. Adaptability to Harsher Conditions

Why Dust Collector Maintenance Teams Should Demand Triboelectric Monitoring

With the push for efficiency demanded by the current economy many industrial plant managers press every department to find new ways to do more with less. In particular, maintenance departments frequently feel the pressure to do more with less, cutting costs but owning responsibility for the same or even increased number of systems. 

For this reason, maintenance departments look for any ways they can to cut capital costs and reduce labor costs. We know it's easy to wish for expensive equipment upgrades or new installations, but  these frequently fall far outside the budget for many facilities. 

How can maintenance departments deal with this situation?

Using Tribo to Monitor Minimum Transport Velocity for Entrained Dust Particles

No matter what the application accumulations of dust within a duct work system can present a host of problems to industrial facilities. Dust buildup in baghouse ducts can impact operations of the dust collection system, thereby directly affecting production. Malfunctioning dust collection also generates respiratory safety hazards as well as creates a substantial risk for combustible dust fires and explosions. Additionally, poorly performing systems directly impact a plant’s emissions limits, which can lead to heavy fines, sanctions or even forced shutdowns by regulators. 

How can operators and technicians prevent this issue and avoid these serious consequences in their facilities?

Why Particle Velocity Monitoring Should be Part of Process Control

One of the topics that generates lots of questions for us in meetings is particle velocity monitoring. Sometimes the reaction is "cool capability, but how's it applicable in our situation?" And if budgets are tight, people assume it will be too expensive and prefer to skip to the next topic. But often the reaction centers around pneumatic conveying where they express a real difficulty understanding what is going on in the pipeline. This is often the case for engineers in industry, and makes troubleshooting an industrial system quite difficult.

Particle velocity monitoring is crucial for proper operation of many process applications and plays a key role in preventing serious problems with dust collection systems that are widely used in nearly every industry. 

For this reason, we thought it would be a good idea to briefly review some compelling reasons why you should seriously consider particle velocity monitoring in your process.
