Historically, many large industrial facilities, including power plants, have relied on once-through cooling, in which the entire cooling water volume flows through the plant heat exchangers and then is discharged to the original source. However, the U.S. Environmental Protection Agency (EPA; Washington, D.C.) has, for over a decade, been developing regulations to protect aquatic life from impingement and...

Adipic acid is a dicarboxylic acid that is widely applied to the production of nylon, polyurethanes, plasticizers and other polymers. Its main use is as one of the raw materials for the manufacture of the polyamide nylon 6,6. In 2012, 80% of the total adipic-acid demand was directed to this application. The traditional production method for adipic acid is based on the oxidation of cyclohexane, a...

How big can a fermenter get? And what would the biggest fermenter look like? The answers to these questions depend upon how the requirements of heat transfer, mass transfer (gas-to-liquid), and momentum transfer (mixing) are met. In an earlier article (Heat Transfer for Huge-Scale Fermentation, Chem. Eng., November 2013, pp. 44–46) the authors described how heat-transfer requirements can cause...

Corrosion and deposition in boilers, steam turbines and many types of process equipment are among the most expensive causes of outages in utility and industrial steam plants. Deposits and scale buildup on heat-transfer surfaces reduce efficiency, and when allowed to accumulate on steam turbines, such buildup can reduce the capacity. Corrosion-related failures can result in outages ranging from a few days...

Industrial microbiology continues to hold the promise of producing an increasingly large array of commercially important chemicals because an ever-wider number of useful microbes is being developed and successfully deployed at commercially viable scales. Today, many of these bio-based chemicals are needed in quantities so large that existing fermentation technology is inadequate, and this is pushing the...

Industrial uses of high-intensity ultrasound have grown tremendously over the past 25 years, says Kenneth Suslick, professor of chemistry at the University of Illinois at Urbana-Champaign and one of the pioneers in the field. Ultrasonic welding of plastics is universal, ultrasonic cleaning of equipment has replaced most solvent and vapor degreasing, and it is even routine for homes to have ultrasonic...

Throughout the chemical process industries (CPI), various chemicals must be injected into process streams to serve a variety of purposes. Chemical-injection systems can be arbitrarily defined as those systems that are used to inject chemicals at a flowrate that is less than 1 to 5% of the main process stream. Table 1 shows a non-inclusive list of chemicals that are typically added into process streams via...

Small chemical reactors offer a number of benefits compared to large reactors, such as better heat transfer and mixing. While small batch vessels are impractical at the industrial scale, continuous flow reactors can provide the benefits of small physical size without the practical difficulties of multiple vessels. This article considers the four basic needs of flow reactors (volumetric capacity, heat...
