Difference between Thermal and Catalytic Oxidation

There are many paths to pollution control. Depending on your industry, exhaust outputs, manufacturing size, and more, you have many options available when looking at pollution control systems. Notably, however, modern pollution control solutions utilize one of two methods to destroy pollutants: Thermal Oxidation and Catalytic Oxidation, both presenting their own pros and cons for different processes.

Today, we will look at the basics of oxidation and combustion, discussing how each process compares and offering you an opportunity to learn more.
Oxidation: Chemically Simple, Operationally Challenging
Something we all learned in our introductory chemistry classes, oxidation is a simple formula for converting […]

    Need Low-Temperature Emission Control? Enter Catalytic Oxidizers

Need Low-Temperature Emission Control? Enter Catalytic Oxidizers

Volatile organic compounds and other air pollutants are produced in industries such as printing, paint manufacturing and various coating processes just to name a few (Paint.org). Because of this, organizations and entities such as the EPA have set regulations that these plants and facilities must attain, with the aim of reducing their environmental impact.

There are different VOC abatement mechanisms that are suitable for different circumstances. For example, catalytic oxidizers offer a great alternative to facilities that have low operating temperatures and low volume exhaust streams.

In this article, we’ll discuss the characteristics of catalytic oxidizers, how they work, and when […]

The Science of Pollution Control: Destruction Efficiency

As we continue our Science of Pollution Control series, we would today like to look at another important consideration in pollution control: destruction efficiency.
What is Destruction Efficiency?
Destruction efficiency is, in simple terms, the effectiveness to which an oxidizer (VOC Abatement System) works.

Sometimes referred to as destruction and removal efficiency (DRE), this is a percentage that represents the number of molecules of a compound removed or destroyed in an oxidizer relative to the number of molecules that entered the system. (For example, a DRE of 99.99 percent means that 9,999 molecules are destroyed for every 10,000 that enter.
Calculating Destruction Efficiency

The Science of Pollution Control: Energy Recovery

As we continue to go through some of the basics of VOC Abatement, discussing some of the basic math and science surrounding the process, today, we would like to turn our focus on something that your accountant might enjoy—energy recovery.

We understand that the decision to update your VOC abatement solution is often an expensive one. Even as a company that designs and provides some of the more cost-effective options in the market, we understand that making a change can still leave a dent on the balance sheet (albeit smaller than a CAA violation or the cost of a lawsuit).

    Choosing the Best VOC Abatement System for Food Manufacturers

Choosing the Best VOC Abatement System for Food Manufacturers

Since the 1970s, food manufacturing facilities are responsible for controlling their dangerous gas emissions. Volatile organic compounds (VOCs) are some of the most common pollutants food factories and bakeries generate, and can severely hinder the environment if released into the atmosphere untreated.

There are now various VOC abatement systems and technologies available that are suitable for different factories, including food manufacturing and packing facilities. In this article, we will provide you with a few tips on how to find the ideal VOC abatement system for your factory.
Do All Food Manufacturers Need VOC Abatement?
As a rule of thumb, only factories that […]

Science of Pollution Control: Understanding Flammability

No matter the industry, manufacturing is a combination of sciences (and scientists) working together to convert raw materials to products. Everything is measured and controlled, and if something deviates from the norm, the inputs are modified to achieve maximum efficiency, minimal variability, and optimal cost.

Pollution control is also a science. However, if you ignore the science of pollution control, you’re likely to need the help of lawyers and public relations professionals to protect your company from the onslaught of fines, lawsuits, and bad press that could hit your company if you violate regulations or break the law.

The CMM Group Releases VOC Abatement Guide

What does new car smell have in common with freshly baked bread? The same thing it has in common with diesel emissions, dry cleaning solution, a can of paint, and a vast majority of manufacturing emissions. All of these are the result of volatile organic compounds (VOCs), carbon-based compounds that exist as a gas in normal temperature and pressure. Many of these compounds are responsible for adverse health, economic, and environmental effects.
Volatile Organic Compounds Pose Threats to Health, Economy, and Environment
While the definition of Volatile Organic Compounds (VOCs) is simple—carbon-based compounds that exist in a gaseous form at normal […]

    The Three T’s of Combustion (and Why They Matter in Pollution Control)

The Three T’s of Combustion (and Why They Matter in Pollution Control)

Today, we’re about to go back to class, exploring the basics of combustion, what it takes to achieve complete combustion, and why all of this is important to VOC abatement at manufacturing organizations.
What is Combustion?
In chemistry, combustion is a basic equation meaning “the reaction of oxygen with anything.” When applied to propulsion (internal combustion engines), heat generation, or pollution control, combustion is understood to be the reaction of oxygen with a compound containing carbon and hydrogen.
Basic Chemistry of Combustion
Also known as “burning,” the combustion process occurs when the initial bonds of a carbon-based chemical are destroyed and bond with […]

Know Thy Enemy: Particulate Matter

What can be said about particulate matter? It’s everywhere. Whether it’s larger, visible particles like dust, soot, or road dirt, or smaller particles that are visible en masse like smoke or smog; these particles can cause a lot of issues ranging from temporary discomfort to chronic health issues, as well as reduce visibility and combine with other chemicals to cause compounded damage.

Following our investigations into Volatile Organic Compounds (VOCs), our deep-dive into their prevalence and removal strategies for VOCs in paint manufacturing, and our look at Hazardous Air Pollutants (HAPs), we would like to look at another ‘enemy’ of […]

The Most Effective VOC Abatement Technologies Available Today

It’s no secret that manufacturing plants, such as paint mills, need to follow rigorous regulations when it comes to disposing of all their waste[1]. This includes the dangerous gas emissions known as volatile organic compounds or VOCs.

These air pollutants are known for causing health complications when concentrated indoors. At the same time, they can also result in the formation of smog and other environmental complications when concentrated outdoors. Finding the most effective VOC abatement technology is critical to creating a sustainable manufacturing facility.

In this article, we will discuss the definition of volatile organic compounds, and highlight the most effective […]
