Tie-in opportunities are few and far between. These rules of thumb will help make sure everything and everyone line up in time A majority of capital projects today are either debottlenecks or revamps that are intended to increase capacity, squeeze…
Figure 1. Vibratory feeders are particularly well-suited for fragile or friable materials, and hard-to-convey powders Figure 2. Today’s advanced electromagnetic drives address many shortcomings of earlier designs The need to move, convey and feed materials exists in virtually all segments…
A new correlation that matches most commercial trays The sieve tray has been in the distillation market place for many decades. It has been used extensively in distillation columns worldwide as a highly efficient vapor-liquid-contacting device. Many people have examined…
The whole-product-lifecycle approach for flowmeters presented here encompasses more than basic selection Typical discussions of flowmeter selection address specifications, technologies, accuracies and performance, but there are many other steps that are not normally considered. This article focuses on these often…
One of the most important factors to consider when evaluating a specialty metal for use in valves, fittings and instrumentation is its corrosion resistance or corrosion rate of the metal in the target media. Each material discussed here has its…
In recent years, a growing number of projects throughout the chemical process industries (CPI) have been carried out using Engineer-Procure-Construct (EPC) contracts. Because such contracts typically involve the work of numerous subcontractor parties, they tend to be complex. As such,…
Technology Requirements [ 1] Control architecture Does the solution provide an integrated automation platform? New systems should manage process knowledge through a combination of advanced technologies, industrial domain expertise, and Six Sigma methodologies. Choose an open, scalable control system that…
Evaporation of moisture or volatile organic compounds (VOCs) from bulk solids usually takes place in two stages: one in which the drying rate is constant, and the second in which the rate decreases over time. Devolatilization during the first stage…
By continuously monitoring for abnormal situations, such as a fire, and combustible or toxic gas releases, fire and gas (F&G) detection and mitigation systems are the linchpins to maintaining overall safety and operation of industrial facilities. The premise of these…
Because temperature control is important in any process, a water-cooling system is a common component in chemical processing plants. For facilities located near coastal areas, the tendency is toward the use of seawater instead of river water for cooling purposes.…
