Mustang (Houston), part of international energy services company John Wood Group PLC, has received Chevron’s (San Ramon, Calif.) Gold Star Award for Safety Excellence, which recognizes contractors with outstanding safety records.  To receive the award, Mustang had to meet strict criteria, including no lost-time incidents or recordable injuries in 2008, while working on Chevron’s El Segundo Refinery...

Figure 1.  Many self-testing ground- ing clamps also monitor cable condition back to the designed ground point, and will alert the operator if the cable has worked tself loose or is broken We are all familiar with the effects of static electricity in everyday life — the sharp spark we experience as we approach a metal file cabinet or the crackle we feel as we remove a garment made of synthetic...

The Department of Homeland Security established the Chemical Facility Anti-Terrorism Standards (CFATS) to impose mandatory security regulations on high-risk chemical facilities. Interpreting and fulfilling the regulations present challenges to security directors, but finding the right guidance and working with a security integrator who has experience in the chemical industry can help achieve compliance...

By continuously monitoring for abnormal situations, such as a fire, and combustible or toxic gas releases, fire and gas (F&G) detection and mitigation systems are the linchpins to maintaining overall safety and operation of industrial facilities. The premise of these systems is to protect processes and the environment by providing early warning of incidents and enabling actions that prevent them from...

Protecting process systems from overpressurization is vital throughout the chemical process industries (CPI). Both safety relief valves and rupture disks are commonly used for this purpose. Sometimes the combination of a relief valve with a rupture disk can add service life to the relief valve and prevent process leakage, which is important from safety, conservation and financial standpoints. This article...

Rupture disc devices provide overpressure protection for a variety of storage and process vessels and equipment. The objective of the rupture disc is to maintain a leak-tight seal and be a passive bystander until called upon to relieve excess pressure. While this is generally the case, there are times when rupture disc performance can be adversely affected through various installation, operation and...

Technical and specialty gases find use in many synthesis processes and a number of unit operations, in analysis and in plant maintenance. This article outlines applications for gases in fine and specialty chemistry, ranging from synthesis processes and inerting to off-gas treatment and industrial services. For each one, processes and the field of use are briefly explained, and existing technical solutions...

Eye injuries of all types occur at a rate of more than 2,000 per day in the U.S., and half of those occur in the workplace. In 2006, the U.S. Bureau of Labor Statistics (BLS) reported over 52,000 workplace injuries to the eyes and face, and approximately 70% of those were eye injuries [1]. The need to protect the face and eyes in the workplace is clear. FIGURE 1.  Safety glasses help shield eyes from...

I would like to draw your attention to a few points on the November 2008 article, Pressure Relief System Design (pp. 40–45): 1. Pressure drop and pressure loss: The inlet pressure “drop” that the author refers to under Relief system piping is non-recoverable pressure loss, and does not include a “drop” in pressure due to elevation increase. It should be labeled as a pressure...

  Pressure relief systems are vital in the chemical process industries (CPI) for handling a wide variety of situations. They are used to prevent pressurization above a system’s design pressure; for venting during an unusual or emergency situation; and for normal depressurization during a shutdown, as examples. In some cases, such as when non-combustible gases including steam, air and nitrogen...

Since the original invention of the steady-stream eyewash over 50 years ago, the accepted practice in the chemical process industries (CPI) and other industrial circles has been to flush the eyes with two, separate, arc-shaped water streams, each one flowing from the outside corner of the eye inward (diagram). A little-known, but potentially serious problem with this approach, says Michael Markovsky, vice...

This article presents the fundamental concepts of the discharge coefficient, KD, of a relief valve or a safety relief valve, and flow resistance factor, KR, of a rupture disk, and their proper use in sizing an emergency relief system. When these devices are used to protect a pressure vessel, they must be certified according to ASME code in the U.S. Both the discharge coefficient and the flow resistance...

Workers in the chemical process industries (CPI) would certainly benefit from the "perfect" glove that would be thick enough for thermal insulation, thin enough to promote dexterity and tough enough to protect workers from cuts and abrasion. The glove would also protect against all known chemicals and be offered at a minimal price. This perfect glove, however, does not exist. Processors and...

A massive fire that injured four workers and caused the total shutdown and evacuation of the Valero McKee Refinery in Sunray, Tex., in February 2007 likely occurred after water leaked through a valve, froze, and cracked an out-of-service section of piping, causing a release of high-pressure liquid propane...

Whether noise is encountered on the job or in the community, most people are at risk of hearing loss if they don’t take precautions. The occupational and environmental health and safety professionals of the American Industrial Hygiene Association (AIHA) believe that noise exposure is an omnipresent issue in our communities and workplaces.

Small-scale chemical producers that use chlorine often rely on larger producers, which sell them the excess Cl2 produced by dedicated chlor-alkali plants. However, such Cl2 supplies are being threatened on a number of fronts, at least in Europe, where new legislation forbidding the import or export of mercury (after 2010) could force older Hg-based chlor-alkali plants to convert to membrane technology or...

Most common acids can be stored in horizontal or vertical ASME-type tanks, as shown in the figures to the right, or vertical API-type tanks. Horizontal, carbon-steel ASME-type tanks of 10,000 — 40,000 gal capacity should have a plate thickness of 3/8 in. with dished heads of the same thickness. The thickness includes a corrosion allowance of 1/4 in., which provides a tank life of 15 — 20 years...
