Polymer-based Piping Systems: Meeting the Challenges of the CPI

Due to favorable properties, such as light weight and corrosion resistance, plastic-piping systems are suitable for a growing number of applications Over the past few decades, plastic-piping systems have been adopted in many different sectors of the chemical process industries…

Valves: Essential Workhorses

Concise tips on selecting the right valve A typical chemical plant contains miles of piping and hundreds, if not thousands, of industrial valves (Figure 1) that are essential for the plant to operate efficiently and safely. Unlike the simple consumer…

Reducing the Noise from Control Valves

Attenuation for high-noise control valves need not be difficult or expensive The world does not lack for noise. It pummels us from all sides, emanating from traffic, political commercials, and your annoying neighbor’s backyard party. Industrial plants have their share…

Facts At Your Fingertips: Crossflow Membrane Filtration Module Types

In crossflow membrane filtration (CMF), feed flow is parallel to the filtration surface (rather than perpendicular to it, as in conventional filtration). During a given pass, a portion of the feed permeates the membrane, while a larger portion is retained…
