HN Series Hydro Cyclones (photo) are designed to separate sand and other solids from water using centrifugal force. HN Series Hydro Cyclones are suitable for use in pre-filtration applications in membrane water-treatment systems. The HN Series is offered in three…
Insono is a new non-destructive testing (NDT) technique for the inspection of composite repairs applied to metallic components. Insono complements this company’s Technowrap range, and provides operators with assurance required by the regulatory bodies. It also allows for the extension…
A decades-old, yet less well-known type of heat exchanger offers advantages for new and emerging applications Spiral-tube or helically-coiled heat exchangers have been around for decades addressing sample cooling, mechanical seal cooling, vent condensers, vaporization and general heating or cooling…
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…
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…
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…
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…
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…
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…
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…
