Thermosiphon reboilers are the new standard in petroleum refineries and chemical plants. Nevertheless, approximately 50% of the world’s reboilers are kettles. In the realm of heat transfer, kettle reboilers have not been understood well. Last month, at ChemInnovations, however, Pete Parker, FRI’s president and my supervisor, cracked the knowledge barrier with insight from nothing other than...

At the 2nd Annual ChemInnovations Conference and Expo (Houston; September 13–15), Hemi-O Technologies LLC (Corpus Christi, Tex.; dixonengineering@gmail.com) introduced its patent-pending technology that enables external access to individual tubes in a heat exchanger while the exchanger is in service and operating at full capacity. The so-called Hemi-O (heat exchanger maintenance and inspection...

To make the modern materials we use every day, such as plastics, metals, electronics, pharmaceuticals, fuels and so on, strong acids are used to convert the earth’s raw materials into modern materials. In fact, so many tons of acid are used (200 million metric tones of sulfuric acid annually worldwide) that the gross domestic product (GDP) of most industrial nations are directly correlated to...

The topic of fouling in heat exchangers has been of increasing interest in recent years, since it is so closely linked to the cost of building and running a chemical plant. It has been reported that fouling costs are about 0.25% of the gross national product (GNP) of highly industrialized countries, which, based on current estimates of GNP for the U.S. of $15 trillion, makes the staggering cost of fouling...

The ever important aim of energy efficiency in the chemical process industries (CPI) is brought closer to its target by the practice of energy recovery in heat exchanger networks (HENs). When heat exchangers are designed to work together to exchange heat between hot and cold streams, the required utilities are effectively reduced. The HEN designer usually applies the assumptions of fixed operating...
