The desire to move from batch to continuous processes for the production of high-value organic molecules has become more widespread in recent years as evidenced by the increasing number of related studies published in the literature. The benefits of continuous…
Faced with increased workloads and time and budget constraints that often restrict external training support, many chemical process operators are forced to get the most out of their heat transfer system with less help. This article offers recommendations for how…
Installed gain graphs can help improve the selection of control valves for chemical processing. The graphs are plotted to analyze together control-valve flow characteristics and process-system flow characteristics, and better illustrate the relationship between a control valve and the system.…
An understanding of the basic information presented here will help you produce powdered products with desired characteristics, while operating the drying plant safely and with minimum energy This photo shows a spray dryer with a heat recuperator. The plant…
Piping represents a major cost for projects in the chemical process industries (CPI). Larger pipe diameters increase upfront capital costs for a project, but the lower pressure drops afforded by large pipes mean less power is required to move the…
The success of industrial R&D activities has a direct impact on a company’s long-term commercial profitability. Today, a variety of market forces, including the drive for growth, the search for new ideas and innovative products, and the increasingly competitive pressures…
Direct-fired heaters find wide application throughout the chemical process industries (CPI) and are common in petroleum refineries, where they are used to preheat petroleum or petroleum-derived feedstocks in advance of downstream process operations. Since excessive internal tube fouling occurs above…
The ultimate objective of storing liquid, fluid and gaseous products, which may be corrosive, flammable or unstable, is to store material in an environmentally safe and economically viable manner. Storage tanks in the chemical process industries (CPI) can be most…
Household items, such as breakfast cereal, flour, corn starch and sugar are so common that many were left surprised after the 2008 combustible-dust explosion at a sugar refinery in Georgia. Heard in much of the early media coverage was the…
Compressed gas cylinders are widely used in research, pilot plant, laboratory and small-scale manufacturing and processing operations as a way to provide a convenient, economical and safe source of high-pressure gases for various applications. These gases can be inert, flammable,…
