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…
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…
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…
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…
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…
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…
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…
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 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…
SLB (formerly Schlumberger) and Linde plc (Guildford, U.K.) announced that they have entered into a strategic collaboration on carbon capture, utilization and sequestration (CCUS) projects to accelerate decarbonization solutions across industrial and energy sectors. The collaboration will combine decades of…
