Wear-resistant screen cloth — with multiple service life
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…
Critical Flanges: Advanced Washers Eliminate Galling and Hot Work
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…
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…
New Delta Hybrid series
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…
This rupture disk improves process performance, efficiency
The technically advanced LoKr reverse rupture disk (photo) delivers a best-in-class flow-resistance factor, KR, to maximize pressure-relieving performance while delivering superior reliability and service life. The disk’s architecture has been refined and optimized to improve performance in three key areas:…
Space-saving, efficient compressed-air production
With a minimal footprint of approximately 1 m², the compact Aircenter systems (photo) are available for flowrates from 0.34 to 2.7 m³/min and also provide application-specific compressed-air treatment and storage. All Aircenter models are characterized by their exceptional efficiency. At…
This twin-screw feeder is certified as OEB 5
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…
Managing Fouling in Heat Exchangers
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…
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…
Toward the Production of Safer Chemicals
A new protocol for safer chemical design is helping to overcome gaps in ‘traditional’ toxicology and improve upon federal regulations for endocrine-disrupting chemicals Research over the past two decades shows clearly that some chemicals manufactured for product functionality can have…
