Sandvik AB (Stockholm, Sweden) has completed the previously announced acquisition of the mining related business of Schenck Process Group (SP Mining). SP Mining is one of the market leaders in screening, feeding, screening media and train loading solutions in the…
At Powtech last month, this company presented completely new, more wear-resistant screen cloths that, compared to previous standard cloths, achieve an increased service life with abrasive bulk materials. Matched to the wire thickness and mesh size, the screen cloths are…
In June, the newly developed, dust-tight OEB version of the DDSR20 2.0 twin-screw feeder (photo) passed the highest occupational exposure bands (OEB) classification certification, OEB5. OEB classifications are used to grade substances accurately into “classes” or “ranges” based on the…
This C Series heat exchanger (photo) replaced an older shell-and-tube design that had high operating costs, due to a 2.4 psi pressure drop. While both old and new units have the same capabilities, the new C Series pressure drop is…
The Delta Hybrid series (photo) offers an innovative solution for the pneumatic conveying of sensitive, powdery and granular media. The rotary lobe compressors or screw blowers can offer maximum energy efficiency, minimum lifecycle costs, 100% pure and reliable process air…
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…
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…
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…
Fouling of heat exchanger surfaces reduces thermal efficiency. An improved understanding of fouling and the design factors that affect it can help ensure that heat exchange occurs during normal operating conditions Using tubular heat exchangers is an efficient and reliable…
During vessel breakout activities, plants should pay close attention to the design of the washers used on bolted flanges. A simple change in this area can help to reduce downtime and improve safety Bolted flanges on vessels, and their associated…
