A look at the hidden dangers of lens fogging and how to prevent them Fogging is the number one problem faced by safety eyewear users in the chemical process industries (CPI; Figure 1). Across applications, both indoors and out, the…
From initial conceptualization to final calculation, designing compressors requires not only engineering intuition and robust simulation tools, but also a bit of creativity As technology has evolved, so has the refrigeration industry. What were once holes in the ground filled…
Some practical tips regarding the design and fabrication of piping systems and equipment for high-purity applications are presented here Chemical processing, and the chemical process industries (CPI) on the whole, have evolved lightyears beyond their very beginnings — beginnings in…
A better understanding of what pressure instruments do and how they work can help improve measurement performance, especially in troublesome applications Effective use of process instrumentation is critical in any chemical manufacturing environment. These instruments are strategically located throughout various…
Users should consider both options when selecting a DP device. Understanding the differences can help make the decision for a given set of process conditions Differential pressure (DP) measurements are used in many branches of the chemical process industries (CPI)…
Simulations demonstrate the complex, changing properties of materials within the evaporator. Such information can help in both designing and selecting the proper evaporator A wiped film or agitated thin-film evaporator is very effective with difficult-to-handle materials. The evaporator consists essentially…
Significant improvement in reducing fluid loss, optimizing flow paths and easing operation are among the advances in next-generation coupler technologies According to the National Response Center’s (NRC) “Spills and Accidents” database, which collects data on toxic chemical spills and other…
Understanding pump internals, especially the various sealing and coupling arrangements, is a critical step in selecting the optimal pump There is a significant risk for operators associated with the pump selection process. Economic issues, such as procurement and operating costs,…
Advancements in efficiency and the ability to handle a wide array of chemicals combine to make the air-operated double-diaphragm (AODD) pump a useful choice for chemical processors The circumstances surrounding the development of the air-operated double-diaphragm (AODD) pumping principle six…
Implementing microreactors in chemical production is quite a challenge. How these challenges can be met is described here At the heart of a chemical process is the reactor, where the conversion of reactants to products occurs. Depending on the need…
