The failure of a device or of a group of components can lead to overpressurization and subsequent adverse events, such as fire, explosion, spill or release. The most common causes of overpressurization are listed below. Understanding the circumstances surrounding overpressurization will help an engineer to avoid these failures. External Fire According to API RP 520 and 521 standards, a fire-exposed area is...

This article introduces a simple yet accurate way to calculate the wetted surface area of a partially filled horizontal vessel with semi-elliptical heads. This information is often needed for the sizing of relief devices. API Recommended Practice 521 specifies that a vessel containing liquid, mounted such that its lowest point is less than 7.62 m (25 ft) above ground level, must be fitted with a...

As the chemical process industries (CPI) make the transition from communication protocols and systems that are cable-ready to those that are wireless, the conversation is changing. On the plant floor and in the executive suite, terms such as mesh network and interoperability bring new meaning to the manufacturing environment. But what does it all mean? How can companies truly begin to decode this new...

Steam traps are an integral part of steam systems in the chemical process industries (CPI). Steam is commonly used to add energy into a process through its latent heat (steam heat), while the resultant sensible heat (hot condensate) drains through steam traps. The operation of these traps influences the entire steam system’s function and reliability. Steam trap operation has a bearing on the...

To ensure the health and safety of workers, the U.S. Occupational Safety and Health Administration (OSHA) adopted the Hazard Communication Standard (HCS) in 1983. Initially designed to protect workers in the manufacturing sector, the HCS was expanded in 1987 to cover all industries where workers could be exposed to hazardous chemicals. This article gives an overview of the OSHA requirements for material...

Better control of baghouses and cartridge-type dust collectors can pay dividends in energy savings, longer filter life and effort spent in tracking environmental compliance. That’s the message from Richard Kapcha, a control specialist with MikroPul (Charlotte, N.C.), which manufactures a wide range of dust collection equipment. “Until the early 1990s we were supplying baghouses with cleaning...

    Most columns shut down without fires. Yet most refineries and chemical plants at some time or another have experienced spontaneous or hot work ignitions in at least one column. When this occurs inside a column during or after shutdown, the results can be devastating and dangerous. This paper concentrates on the fires related to packing in columns.   Many refineries and chemical plants...

    Traditional pressure-relief devices are, at times, unable to protect vessels at the elevated temperatures experienced during fires. As witnessed by numerous examples throughout history, loss of containment and the subsequent explosions that may occur with an over-pressurized system can lead to catastrophic results in terms of equipment damage, monetary loss, environmental impact and even...

    Although sealing technologies rarely make the headline, when they do, its usually for a tragic reason, which demonstrates how important this small component really is. For example, on January 28, 1986, the Space Shuttle Challenger disintegrated 73 seconds into its flight, after an O-ring seal in its right solid rocket booster (SRB) failed. The seal failure caused a flame leak from the SRB...
