Why is it that many people on the plant floor use compressed air to clean their machines and the floors around them? It’s easy. That’s why. The problem is compressed air can be the most expensive and most ineffective and damaging way to “clean” machine♦s. Think about...

Methane is the primary component of natural gas. As a country, the United State has been rapidly transitioning, and continues to transition from coal to natural gas as the fuel of choice for generating electrical power. That’s a good-news story for the environment...

It has been 56 years since I changed from a career path in high-speed machinery to employment in the petrochemical and refining industries. Over the course of my work, I’ve had the pleasure of meeting hundreds of value-adders. Conversely, I also have dealt with people...

Fugitive emissions, are a concern across the industrial landscape. Although this article focuses on leveraging predictive maintenance (PdM) to combat the problem in the natural-gas arena, the suggested strategies and tactics can be adapted in any operation where...

One of the hallmarks of a best-practice maintenance organization is its preparedeness and ability to respond to emergency situations, whether they have occurred or could occur. The definition of an emergency is commonly understood to be a situation or occurrence that...

“Human error” is an often-cited cause or contributing factor in accidents and failures. We routinely see this with our plant equipment. But, identifying ways to reduce or eliminate “human error” can be challenging without a structured process for indentifying and...

One of the least understood, yet critical, components of power quality is the grounding system. While we cannot cover all variations of these systems, it’s important to note that the primary methods are grounded/bonded; resistance ground; and,...

As noted in previous articles in this series on motor-driven equipment and electrical-system-reliability issues in today’s plants, the primary electrical concern is the supply to electric motors, i.e., the voltage. An electric motor is electrically designed around the...

Voltage unbalance and its most severe form, single phasing, cause up to 14% of power-quality-related motor failures. It’s important to understand that maximum current unbalance is not defined in standards for electric motors in their operating environment,...
