High-Purity Water Simplified
There are a number of process technologies available to meet the strict standards for high-purity water in different industrial sectors It is easy to think that the water coming out of our faucets can be used anywhere. Although potable water…
Updating Legacy Rotating Equipment
A brief look at the benefits of installing modern materials and design upgrades through retrofit projects in chemical plants Modern chemical manufacturing plants depend on the reliable operation of numerous important assets to maintain productivity. Retaining legacy equipment is a…
Determining Overall Pump Lifecycle Costs
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…
Sustaining Effective Process Safety Programs at CPI Facilities
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…
Sampling System Design: Managing System Variables
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…
Evaporators: Design Concepts and Equipment Selection
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…
Storage Tanks: Snapshots of Failures, Damages and Inspections
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…
Standard ASME B16.5 Flanges: Bolt Tightening and Target Loads
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…
Interpreting Normalized Profitability Metrics
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…
ASTM Standards For Heat Transfer Fluids
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…
