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...

The scaleup of liquid mixing systems does not have to be a mystery. The principles are quite well understood, although knowing which principles apply is not always obvious. Follow this guidance to improve operation. 1. Liquid mixing scaleup. Liquid mixing is the most common use of scaleup methods in chemical engineering. The concept of scaleup is to take small-scale results and predict results in...

Polymer-based piping systems offer a number of advantages, along with some limitations, compared to metallic and other non-polymeric pipe materials. The use of thermoplastic piping in the chemical process industries (CPI) must be carefully considered on a case-by-case basis because of the constraints introduced by various CPI applications. Polymers remain only a small (~10%) part of the global CPI piping...
