One hundred years ago, on Oct. 14, 1913, the Senghenydd Colliery in Glamorgan, South Wales, exploded, resulting in 439 fatalities. This was the worst coal mine disaster in the history of the U.K. The incident is believed to have been started by...
Air is always all around us, and the oxygen it contains is necessary for life. But, compressed air (or any other compressed gas) contains a lot of energy and can cause major damage if a vessel or pipe fails.
Chemical engineering as it is known today — in which theoretical models are used to design and maintain processes — bears only a slight resemblance to the nascent field. In its beginnings, chemical engineering involved the dissection of chemical processes into unit processes and unit operations using mostly empirical methods. Material and energy balances soon entered the scene in the late 1920s, followed by the introduction of transport phenomena. While many scientists and engineers contributed to the evolution of chemical engineering, one man in particular stands out. Neal Russell Amundson, who became a full professor of chemical engineering at the Univ. of Minnesota at the age of 35, can be credited for the proliferation of scientific content within the chemical engineering field and profession.

Chemical engineers and sound engineering principles have been absent from the discussions of global challenges — energy, climate change, food, and water — for too long, assert Bill Banholzer and Mark Jones of Dow Chemical in their August AIChE Journal Perspective article, “Chemical Engineers Must Focus on Practical Solutions.” Society has thus confused what is possible with what is practical, particularly when it comes to energy, where new discoveries are greeted with over-excitement and the hope that each will provide the means to supply reliable, cheap, and almost-limitless energy, the authors say. They cite the hydrogen economy, cellulosic ethanol, and fuel cells as examples of technologies that have promised much but delivered little

The chemicals industry is a pillar of Singapore’s economic success. The island city-state’s emergence as a chemical industry leader has been boosted by investment in infrastructure and the creation of an industrial island complex.
What a difference a few years can make! In mid-2005, I wrote a column (for another publication) entitled “The U.S. Chemicals Industry, R.I.P.” The situation got no better for the next few years, but starting toward the end of the last decade, based on improved extraction methods, U.S. natural gas production began to grow rapidly.
