In today’s environmentally conscious world, industrial energy management is increasingly recognized as an essential business practice and economic necessity, rather than an on-again, off-again activity driven by energy prices and geopolitical crises. In this article, we examine the key elements…
The average large project in the chemical process industries (CPI) overruns its sanctioned budget, including contingency, by 21%. Even more alarming, 10% of large projects overrun their budget by more than 70%. These are findings based on research by the…
The alcohol n-butanol is applied in the production of butyl acrylates to supply the coatings and adhesives industries. It is also used in plasticizers or directly as a solvent. It is commercially produced from propylene and synthesis gas (syngas) by…
Bulk solids are frequently used as reactants, catalysts or products in chemical process industries (CPI) operations. Often, they must be heated or cooled so that they can be handled safely or processed at a desired temperature. Traditionally, heat transfer to…
Experiments are done to quantify cause-and-effect relationships between adjustable parameters (inputs, factors, x) and the results (outputs, responses, y). They help to answer questions like: How do the ingredients and proportions of a mixture (inputs) influence its properties (outputs)? How…
Figure 1. During tightening, hydraulic pressure load within a bolt should be uniformly and accurately applied to avoid gasket damage and other issues that can create leakage Common knowledge dictates that planning ahead ensures effective results, regardless of the task…
Methionine is an essential amino acid that is not synthesized by animals, so it must be obtained from their diets. Synthetic methionine is traditionally commercially available in two varieties: D,L-methionine (DLM), a racemic mixture of the two stereoisomers, and methionine…
Burners are mechanical devices that are utilized for mixing proper quantities of fuel and air, and also for maintaining a stable flame inside fired equipment. Burners are critical components that must be periodically maintained to ensure the reliability of fired…
This letter is in reference to the article, Forces Acting on a Gasket [ Chem. Eng. October, 2014, p. 32a]. I need to clear my understanding on the seating stress required for the proper sealing. As per the article, seating…
Fabricated metal-wire mesh is one of the major categories of filter media. Woven metal cloths are often used to support a filter aid coating or a bed of granular or porous material. Proper selection of wire cloth can have a…
