Substituting oxygen for air is often a low-cost, easy-to-implement option that can reduce capital costs, lower emissions, and improve process flexibility and reliability.
Annual operating expenses for compressed air systems can exceed the equipment’s purchase price. Follow these seven steps to implement efficiency measures that yield cost reductions.
Many safety instrumented systems rely on dissimilar redundant field devices, and this can complicate required analyses. These equations will enable field personnel to handle such situations readily.
Faced with more distractions than ever, operators need an environment that is conducive for dealing with abnormal, as well as normal, situations. Effective control room design can help.
In a petroleum refinery, viewing hydrogen as an asset rather than a liability can lead to increased profits. The key is in the mindset. A typical investor uses money to make money. This article shows you how to use hydrogen to make money.
The new parameter introduced here will yield more meaningful results when a fixed-bed reactor is scaled up for process development or scaled down for plant support.
Finding the proper nozzle for specific applications doesn't have to be difficult. By applying basic concepts of nozzle technology, you can create a droplet profile that best suits your needs.
