(From November 2011, Letters) Perhaps enough has been written about the questionable science underlying recent U.S. government pronouncements concerning formaldehyde and human cancer of the lymphohematopoietic system (“LHPs—including the leukemias and the lymphomas)*. Now, suppliers of formaldehyde-containing product must face the uncertainties and high expense of defending questionable and...

Last month, two significant cracks were found in the cornerstones of conventional thinking about how chemicals in the environment make their way into the human body and other living organisms, possibly leading to damaging effects. The timing is particularly apropos, as the first registration deadline of November 30 approaches for the EU’s regulation on Registration, Evaluation, Authorization and...

Wireless communications have great potential in the chemical process industries (CPI) because they do away with complex and costly cable installations and enable completely new applications. And while a recent wave of successful demonstrations has begun to emerge in the CPI (for more, see CE, Nov. 2009, p. 17–23), a number of hurdles stand in the way of a completely wireless Utopia. In most cases...

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...

Reduce the problems associated with handling hazardous liquids by following these guidelines Pumps are one of the most ubiquitous items of equipment found in chemical processing plants. Often, they are used to transfer hazardous liquids, such as flammable, combustible, toxic and corrosive chemicals. In order to ensure safety during pumping, certain design and operating practices should be followed. This...

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...

    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...

    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...

    Chemicals, plastics, pharmaceutical, food, agricultural chemicals, coal and bio-chemical industries have a wide array of processes where the raw materials, intermediates and products are in particulate form. Hazards associated with particulate solids are unique, and in most cases depend on the particle size. The purpose of this paper is to present a systematic framework for designing...

    Liquids are accumulated and stored in tanks of various shapes and sizes throughout the chemical process industries (CPI). A small number of companies have made the design, fabrication and erection of these vessels their specialty. Initially, however, it is the process engineer who sizes and specifies tanks according to a specific application’s needs. In order to develop a data sheet for...

    Hydrogen is widely employed for hydrogenation and other purposes in chemicals manufacture, petroleum refining and other chemical process industries (Hydrogen: The Real Action Is Today, CE, February, pp. 28ff), and it holds promise as a fuel. However, this gas is highly explosive, prone to leakage and permeation, and difficult to detect, so special care must be taken during process engineering...

Phosgene is widely used for making fine chemicals, pharmaceutical intermediates, and polymers such as isocyanates, polyurethanes and polycarbonates. But phosgene is highly toxic, and although gas detectors are required to monitor for dangerous leaks, they cannot determine if workers have been exposed to low (below-threshold) concentrations over long periods of time, says...

Toshishige M. Suzuki and his colleagues at the Tohoku Center of National Institute of Advanced Industrial Science & Technology (AIST; Sendai, Japan; edlinks.che.com/5827-538) has developed a new analytical test strip that can quickly detect parts-per-billion (ppb) concentrations of heavy metal ions in water. Up to now, existing test strips for metal ions have not been sensitive enough to detect ppb...
