This online engineering PDH course provides guidance on a common problem facing environmental engineers and that is how to evaluate and treat an odor problem. Odors are not always toxic, but the nature of odors often causes people to act emotionally and demand that the source be eliminated. However, the nature of odorous compounds is that even a very low concentration can trigger detection or other reaction.
This course describes the nature of odorous compounds, how they are detected, their typical sources, and approaches and technologies commonly used to control them. It presents the factors and information necessary to assess an odor situation and how to approach it. It provides an overview of how to proceed in treating an odor episode and presents real life situations.
This 2 PDH online course is applicable to chemical and environmental engineers involved at the facility level to determine how to technically approach an odor episode and treat it effectively.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Familiarizing with the nature of odorous compounds
- Understanding the basic characteristics of odors
- Learning about the different sources of odors and the corresponding types of odorous compounds
- Learning how to approach remediating an odor problem once it is detected
- Learning about common odor control technologies to properly solve the odor problem
In this professional engineering CEU course, you need to review the course document titled "Overview of Odors".

This online engineering PDH course provides guidance on the responsible use and selection of refrigerants in vapor compression refrigeration systems. The thermodynamic efficiency of a refrigeration system depends mainly on its operating temperatures. However, important practical issues such as the system design, size, initial and operating costs, safety, reliability, and serviceability etc. depend very much on the type of refrigerant selected for a given application.
Due to several environmental issues such as ozone layer depletion and global warming and their relation to the various refrigerants used, the selection of suitable refrigerant has become one of the most important issues in recent times. Replacement of an existing refrigerant by a completely new refrigerant, for whatever reason, is an expensive proposition as it may call for several changes in the design and manufacturing of refrigeration systems. Hence it is very important to understand the issues related to the selection and use of refrigerants.
This 2 PDH online course is applicable to HVAC engineers, facility engineers, architects, environmentalists, operations and maintenance personnel, as well as consultants and contractors who construct, build and manage facilities.

This online engineering PDH course describes best practices and programs related to leak detection and repair. It also provides detailed information about sources, causes and control of equipment leaks.
Leaking equipment, such as valves, pumps, and connectors, are the largest source of emissions of volatile organic compounds (VOCs) and volatile hazardous air pollutants (VHAPs) from petroleum refineries and chemical manufacturing facilities. Emissions from equipment leaks exceed emissions from storage vessels, waste-water, transfer operations, or process vents. Such emissions are known or suspected of causing numerous detrimental health effects and they frequently cause significant financial losses due to lost products and fines.
This 2 PDH online course is applicable to environmental, chemical, process, and mechanical engineers, as well as design and construction personnel involved with leak detection and repair at refineries, chemical plans, power plants, and many other facilities that utilize pumps, connectors, valves, open-ended lines, pressure relief valves, and sampling connections.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Reviewing the importance of regulating equipment leaks
- Learning the major elements of an LDAR program
- Reviewing typical mistakes made when monitoring to detect leaks
- Learning problems that occur from improper management of an LDAR program
- Knowing best practices that can be used to implement an effective LDAR program
- Reviewing EPA's Method 21 General Procedure
In this professional engineering CEU course, you need the review the course document which is based on the EPA Publication, "Leak Detection and Repair. A Best Practices Guide" published by the United States Environmental Protection Agency. The course document includes complimentary appendices related to Method 21, enforcement alerts, and a summary of NEIC comparative monitoring results of leaking valves at a number of refineries.
Once you complete your course review, you need to take a multiple-choice quiz consisting of fifteen (15) questions to earn 2 PDH credits. The quiz will be based on this EPA Publication.

This online engineering PDH course begins with a thorough explanation of the business (non-regulatory) reasons that every business can benefit from a climate change program and how to institute such a program. Then it covers how to estimate GHG emissions based on globally accepted standards. It also covers how to estimate GHG emissions from the processes you control and how to estimate them from other processes related to your product that your company may not have direct control over ("carbon footprint").
This course also describes how to conduct a life cycle analysis to enable your company to focus intelligently on effective GHG emission reduction strategies. Then, it discusses GHG emission reduction opportunities, including the basics of conducting an energy audit or assessment. Finally, it provides advice on how to manage your GHG emissions and reductions, set achievable goals, and to report successes.
As a result, there is growing pressure for companies and people to reduce GHG emissions with the hope of reversing climate change and its effects in the future. The Kyoto Protocol and other initiatives are introducing incentives for businesses to reduce GHG emissions. Climate change is ultimately a technical issue and must be addressed by different engineers (mechanical, environmental, chemical) applying their specialty knowledge to reduce GHG emissions.
This 2 PDH online course is intended for environmental engineers, mechanical engineers, HVAC equipment specialists, and construction workers who are interested in gaining a better understanding about implementing a climate change program.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understand the nature and importance of the issue of climate change
- Explain why it is not just an environmental issue, but a core business value

This online engineering PDH course provides an introduction to the various types of wet scrubbers, as well as their design and cost considerations.
A wet scrubber is an air pollution control device that removes particulate matter (PM) and acid gases from waste gas streams of stationary point sources. The pollutants are removed primarily through the impaction, diffusion, interception and/or absorption of the pollutant onto droplets of liquid. The liquid containing the pollutant is then collected for disposal. There are numerous types of wet scrubbers that remove both acid gas and particulate matter.
This 5 PDH online course is intended for use by chemical or environmental engineers, design professionals, construction personnel and others involved in the planning, design and construction of air pollution control systems using wet scrubbers.
