Pinch analysis is a systematic method to maximize energy recovery from process streams entering and exiting process equipment. Using this method, the minimum thermodynamic requirements for hot and cold utilities can be calculated for a process. This is useful to determine areas where savings can be realized and where savings are not available. It is a method that can be used during the design of a process...

A well-operated steam generator can save money. In a steam-driven turbine system, water is heated in the steam generator to produce high-temperature, high-pressure steam. Steam is then expanded in a turbine to produce electricity from a generator. Turbine steam is condensed back into water in the condenser. A pump then returns the water to the steam generator. Engine thermodynamics Theoretically, the most...

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...

Yesterday, U.S. District Court judge Paul Friedman denied a legal motion by the U.S. Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) that would have prevented environmental groups from challenging EPA's stay of proposed changes to the Maximum Achievable Control Technology (MACT) standard for industrial boilers. While the decision was procedural, it suggests to ACC that the stay is...

Last year, the U.S. Environmental Protection Agency (EPA;Washington, D.C.; www.epa.gov) proposed new emissions standards for hazardous air pollutants (HAP) emitted by industrial boilers and solid-waste incinerators (CISWI) based on the performance of the maximum achievable control technology (MACT). The so-called “boiler MACT” final rules were signed by the EPA Administrator on February 21...

A well designed and operated heat-transfer-fluid system is a key feature of a safe, reliable and cost-effective heating design. However, problems can arise if the heat-transfer fluid becomes heavily degraded or the system is allowed to accumulate solids and other process contaminants. These problems include the following: • Reduced heat-transfer rates • Diminished fuel efficiency • Flow...

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...
