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...

Late last week, the U.S. Department of Homeland Security released Appendix A of the Chemical Facility Anti-Terrorism Standards (CFATS), a critical element of its chemical security efforts. The appendix contains a list of chemicals that, if possessed by a facility in a specified quantity, trigger a requirement to complete and submit an easy-to-use, online consequence assessment tool called a Top-Screen...

    Safety instrumented systems (SIS) are in the spotlight these days. More companies have come to recognize the importance of recently published consensus standards, and recent fatal accidents tied to the failure of instrumented safeguards have brought further attention. The result is that facilities all over the world are looking at their safety interlocks and concluding that what they really...

    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...

  The preparation of a unit for restart requires complex and systematic approach. A plant restart project is traditionally composed of four steps: 1. A detailed unit-status evaluation 2. Preparation for onsite work 3. Major onsite work, which involves significant expenses for personnel, supply, equipment renting and contractors 4. Restart of the plant, which focuses on bringing the unit online. Upon...

    Occupational dangers in the chemical process industries (CPI) are many, with falls, respiratory hazards, and explosion risks confronted daily. One hazard, however, causes no pain nor visible scars. Its effects accumulate with each overexposure and can go unnoticed, often for decades. If statistics are any indication, it is the most common permanent and preventable occupational injury at the...

  After nearly a decade of preparation and debate, the European Commission's REACH legislation - a system for the registration, evaluation, authorization and restriction of chemicals - was adopted by the Parliament last December, and enters into force on June 1, 2007. Chemical producers, rather than government authorities, will be legally obligated to conduct and communicate assessments regarding the...

    Security is on everyone’s mind. Heightened awareness and concerns have affected the way we live and the way we work. Those of us who are part of the chemical process industries (CPI) and have a great respect for the materials we work with, are well aware of the importance in safeguarding against potential threats. Indeed, the U.S. Dept. of Homeland Security (DHS; Washington, D.C....

    Even with the best process design, the unexpected can happen. Anticipating this, rupture disks are often installed as the last line of defense against the over-pressurization of equipment used for the manufacture, transport and storage of many types of chemicals, petrochemicals, medicines, plastics, powders, food and beverages. When handled and installed properly, rupture disks are a safe and...
