This month the U.S. Environmental Protection Agency issued for the first time ever rules regulating carbon emissions for power plants. These new regulations have brought controversy, with many claiming that regulating carbon emissions in not only unnecessary, but will terrifically affect the US economy for the worse. Other claim that the effect will be more than offset by the benefits of reducing the pace of climate change, which they hold is primarily caused by greenhouse emissions.

It is not our point to delve into the issues involved in the EPA’s Clean Power Plan, or even climate change in general. However, it has spurred yet another fierce debate about pollution laws and regulations, air pollution control technologies and their economic effects on the nation. It leads one to thinking about industrial dust collection and what it costs the country’s economy. Do environmental rules protect or hurt the economy?

While there are many facets to this debate, we wanted to look at just one area today; how much revenue the does the dust collection industry directly cost or add to the US economy each year?

Dust Collector Systems, and Other PM Control Systems Add Billions to Economy Each Year

While politicians debate over increased regulation, there really should be no debate about whether the environmental technology industry is a valuable contributor to the country’s economy. The facts show that, regardless of the political rhetoric on both sides, the sector contributes a great deal to U.S. economic growth.

Today, the global environmental technologies market (including dust collection), which is broad and encompasses products and services for air, water, and soil pollution control, is around $800 billion. The U.S. is the largest supplier and consumer of this equipment and services in the world. Approximately 119,000 firms generate $300 billion in revenues supporting close to 1.7 million jobs. (1)

Trade Surplus From Environmental Exports

The U.S. exported pollution controls worth nearly $40 billion and generated a trade surplus of nearly $13 billion in 2007. In terms of exports as a percentage of total U.S. ET production, the leading sub-sectors are: resource recovery (58 percent); instruments and information systems (46 percent); water equipment and chemicals (36 percent); waste management equipment (25 percent); and air pollution control (16 percent). (Figure 1)

The air pollution control equipment sub-sector, not including engineering and consulting, generates revenues of more than $18 billion each year. A further breakdown of the numbers shows that dust collection equipment exports —  dust collector systems, dust collector filters, baghouses, etc. — in 2008 added up to more than $300 million. Adding in engineering and consulting services pushes that number over $1 billion. With an economy that is feeling the pressures of excessive foreign debt, trade imbalances, and lackluster growth, this sector of the U.S. economy certainly is carrying its own weight.

The Outlook: Advantages and Challenges Lie Ahead

As the situation stands now, the U.S. ET sector, including dust collection technology, holds some distinct advantages over foreign competitors. However, that advantage has been slipping away, little by little, and assuring future growth will prove to be a challenge.

While the United States market remains the largest single ET market, it’s also the most mature. Foreign markets, particularly those in developing countries, continue to grow at a higher rate, offering the most opportunity for U.S. companies.

According to a report by the Office of Energy and Environmental Industries’ Environmental Technologies Trade Advisory Committee, which is made up of governmental agencies responsible for fostering growth of U.S. exports, there are several notable barriers to increasing U.S. trade in this area. They include lengthy and/or nontransparent approval processes, incompatible standards, and legal and regulatory framework issues. Nonetheless, the report also states that the U.S. is well-positioned to compete on the international scene due to factors such as market share, workforce experience, and a highly advanced development process that leads to innovation.

The U.S. share of foreign ET markets went from 5.7 percent in 1997 to 9.8 percent in 2007, giving the industry a positive trade surplus. Although the rate of growth slowed, it has been returning steadily, influenced, in part, by the booming global demand for renewable energy technology.

Another large driver of the growth in developing markets has been the increased number of governmental pollution regulations. While in other industries environmental laws and regulations are seen as a source of extra cost and burden, the opposite is true for the ET sector. Complying with these regulations requires investment in products and services that help prevent, remediate, and alleviate environmental degradation. The ET industry supplies those goods and services.

Less-Obvious Financial Benefits

Dust Collection Economy

U.S. environmental technology exports in 2008

A clean and healthy environment (specifically clean air) has a host of benefits to people that directly affect them economically.  Preventing environmental degradation prevents pollution-related health problems and premature death, and improves the health and productivity of the U.S. work force.

While it can be difficult to quantify in monetary terms the effect of keeping people healthy and giving them better lives, several studies do exist that show that even in these terms environmental control regulations, specifically particle pollution control (e.g. dust collectors) have had a massive impact. A 2011 EPA  peer-reviewed study concluded that the 1990 Clean Air Act Amendments have yielded direct benefits that tremendously exceed their costs. The study’s central benefits estimate in 2020 exceeds costs by a factor of more than 30-to-1, and the high benefits estimate exceeds costs by 90-to-1. (2)

The Path to Growth?

Now more than ever, to get back on the path to recovery, this economy needs to do what it has always done best — innovate and lead. Few sectors of the economy are better suited to do this than the ET industry. With new laws and regulations making environmental compliance tougher, U.S. firms are — out of necessity — finding, developing, and creating new ways to continue expanding while reducing environmental impacts. This experience has provided U.S. companies with the opportunity to get an edge over the competition, and they must take advantage.

The size of the world market for environmental goods and services – $782 billion – is comparable to the aerospace and pharmaceutical industries and presents important opportunities for U.S. industry. In 2008, the United States’ environmental technologies and services industry supported 1.7 million jobs. The industry generated approximately $300 billion in revenues and exported goods and services worth $44 billion – larger than exports of sectors such as plastics and rubber products. Air pollution control equipment alone generated revenues of $18 billion in 2008, including exports of approximately $3 billion.

Without a doubt, over-regulation and governmental bureaucracy can stifle economic growth. However, the ET industry, rather than being part of this systemic problem, is, in reality, part of the solution. This industry is a highly adaptive, com- petitive, and useful one that has proven its worth by creating mil- lions of jobs and billions in profits and trade surpluses. If every sector of the economy had similar characteristics, it would be back on the path to growth.

Baghouse.com

Baghouse.com News | Beginning June 1st, new customers in the Los Angeles and San Diego areas can request free site visits from Baghouse.com. Visits from a dust collector engineer provide far greater value than the usual method whereby companies merely send manufacture’s representative to pitch products.

Upon request, a dust collector engineer will arrange to visit the facility and conduct a condensed version of a standard dust collection system audit. They will visually inspect and review the plant’s dust collectors (if exceptionally large facility , then only primary units), review operating conditions, maintenance procedures, and discuss overall system performance and issues with operators and maintenance personnel. After reviewing the data, the dust collector engineer will present a set of recommendations to improve system efficiency, capacity, and service life of filters, while also reducing maintenance, operating costs (e.g. electricity, compressed air usage, replaceable parts, etc.) and system downtime. If any specific issues are identified during the inspection, or presented by plant personnel, these also will be addressed in the report.

Best practice for installing a baghouse magnehelic differential pressure gauge

This simple baghouse accessory can mean the difference between a properly functioning baghouse and an operational disaster! Use this guide to ensure proper installation and maintenance of your differential pressure device.

One of the most common issues we identify during our dust collection system audits/inspections  is poorly installed and maintained differential pressure system components (e.g. magnehelic/photohelic gauges, DP air lines, DP taps, etc.). As we have covered in previous articles in this series, having accurate differential pressure readings is essential to proper dust collector operation.

Baghouse differential pressure air lines

Avoid the example here. Avoid splitters and crooked lines.

I was recently asked by one of our readers if we could write an article on how to install the differential pressure reading system components for a baghouse. The process, like many baghouse-related items, is not complicated. However, there are some industry best practices that make maintenance easier and reduce likelihood of problems in the future.

This guide can be used regardless of what kind of differential pressure reading system you are going to use. The process is the same for magnehelic and photohelic gauges, as well as timer boards and control boards with on-board pressure sensors.

Installing a Baghouse Differential Pressure System

  1. Determine what kind of differential pressure controls you will use
    • Magnehelic gauges are simple and provide reliable data. However, they alone cannot be used to control the cleaning system on a baghouse.
    • Timer boards are useful for processes that are consistent in dust loading and operating schedules, but must be manually set by operators.
    • Clean on demand systems are the best choice for controlling a dust collector. Often, these systems are all in one controllers, or they are a mix of a control board with an external photohelic or magnehelic gauge for pressure readings
    • Air lines running between the controls and the baghouse can be plastic, carbon fiber, or even metal (copper or aluminum). Plastic or carbon fiber lines are easier to run, but metallic lines are much more durable and will require far less maintenance in the long run.
    • Consider installing secondary magnehelic gauges for redundancy and easy reading by maintenance personnel.
  2. Decide on the location of your control(s)
    • Locate your controls where they can be easily accessed by maintenance personnel. With smaller units often the most convenient location for controls and gauges will be on the ground level. Good locations include on supports or nearby walls. On larger units, controls are best located near the doors or along access platforms. Common locations include next to the door, above the pulse valves and compressed air header, or on a nearby wall or column.
  3. Decide on the location of your air taps and plan your air line runs
    • Air taps are best placed near the corners of the clean and dirty plenums. This minimizes the amount of dust that can enter back into the air lines and possibly foul the DP sensors. Try to keep them about at least 6″ from the walls and in the corners where practical. Keep both taps near each other for easy access when performing maintenance.
    • Decide on the best path for your air lines. Avoid runs over 100′ as this may affect the accuracy of the readings.

Common Issues with Dust Collector Differential Pressure Gauges

Problem: I hooked up the DP lines, but my DP sensor is giving me a negative reading.

Solution: You likely have the lines mixed up. Try switching the lines on the inputs.

Problem: I have the lines set up correctly, but I am getting very low readings (usually under 1″).

Solution: Before installing the both lines, you need to zero out the gauge. Attach one side and then with the other one off zero out the DP sensor. Now when you attach the second line it should give an accurate reading

Problem: My controller is setup, but the solenoids are not firing.

Solution: Check your wiring to make sure you have everything correct. Often, the common line from the solenoid to the control is mixed up with one of the control wires. Double check everything and follow the wiring diagrams from your manufacture exactly.
