Gear units play a critical role in a diverse array of chemical process industries (CPI) facilities, to match the speed of a selected driver with the speed of the driven equipment. Today, they are used extensively in pumps, turbines and compressors, in material-handling units (such as conveyers and stackers), and in other equipment, including mixers, kneaders and extruders. This article discusses...

Working in close proximity to the high pressures and temperatures commonly found in the chemical process industries (CPI) is cause enough for concern over a person’s wellbeing; but working in close proximity to chemicals that are considered toxic, hazardous or reactive escalates that concern to a higher degree (Figures 1 and 2). The dangers of such chemicals underline the paramount importance of...

Optimizing fan performance can help plants reach overall process efficiency goals. The cost of powering fans and ventilators in the chemical process industries (CPI) is significant. For example, ventilation and air-pollution control systems can account for over a quarter of energy a facility’s consumption. Fan performance is typically estimated by using a graph that shows the different pressures...

Let’s face it, valves may not be the most glamorous piece of equipment in a chemical process industries (CPI) facility, but no plant can function without them. In addition, multiple challenges and issues specific to the chemical processing industry affect valves and valve performance. For these reasons, selecting the right valve — one that will stand up to the rigors and demands of the chemical...

Rotary equipment, such as centrifugal pumps, often represent the heart of plants in the chemical process industries (CPI). A critical factor in the longterm reliability of such equipment is a high-quality design and commissioning process, so that initially, the rotary equipment will have the maximum built-in strength to survive upset operating conditions, yet not be overdesigned in a way that leads to...

Proper steam-trap sizing is critical to efficient and reliable steam-trap operation. Incorrect steam trap sizing can undermine the design and function of the steam trap, create installation issues, and cause condensate backup, steam loss, or both. Steam-trap sizing refers to the internal discharge orifice for condensate. Unfortunately, it is sometimes confused with the size of the end connection or piping...
