Beyond the purchase price, there are other optimizable costs that will help moderate pump-related expenses, when estimating pump lifecycle costs Facility managers who rely on industrial pumps for the various liquid-transfer duties in their manufacturing processes may occasionally think that…
The elements needed for excellence in a process safety program are known, but achieving top-level process safety performance requires sustained effort and focus Efforts to achieve excellent process-safety performance at chemical process industries (CPI) facilities are nothing new [1]. Experience…
Understanding the effect of flowrate, velocity, density, viscosity, pressure drop, friction, components and sample line sizes will help you design a sampling system The primary goal when designing an analytical sampling system is to ensure timely, accurate measurements. The sooner…
This primer provides guidance on key aspects to consider when designing and specifying evaporators, which are used in a diverse array of industrial sectors Industrial evaporators are used to remove a solvent from a non-volatile solute to obtain a concentrated…
Lessons learned from past failures provide insight and know-how needed toinspect and operate storage tanks reliably Storage tanks are a common sight at many facilities of the chemical process industries (CPI). Tanks are part of our everyday life and they…
Using the approach outlined here, piping engineers can select the most appropriate bolt-tightening technique based on pressure class and flange size, and calculate the required torque or tool pressure if hydraulic tensioning tools are used In the majority of industrial…
Normalized profitability metrics provide a basis for comparing the efficiency of capital investments, but they are often misunderstood. New interpretations of these metrics can help engineers to make more informed decisions In a financial sense, a large capital project can…
This practical overview of ASTM standards can serve as a roadmap when selecting and evaluating heat transfer fluids Heat-transfer-fluid systems are often used for process heating to 500°F or higher. To accomplish heating above 500°F, steam pressure must be above…
Working with supercritical fluids poses challenges when designing heat exchangers. Some practical tips and precautions are presented here Industrial applications involving fluids at high pressure — pressure above the critical pressure of a particular fluid — are increasing in number.…
In low-temperature conditions, the use of compatible sealing materials is essential for leak-tight operation and proper functionality of pressure-regulating devices Harsh, frigid conditions are among the most challenging industrial environments (Figure 1) for fluid-handling applications. At these temperatures, it is…
