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...
