The chemical process industries (CPI), like many others, increasingly employ non-metallic piping systems for fluid transfer — including polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) and fiberglass-reinforced plastic (FRP) — instead of exotic metal piping. While non-metallic piping systems have…
Maintaining high-purity conditions in the chemical process industries (CPI) depends in large part on the techniques used for sterilization. As a method to inactivate or eliminate potentially harmful microbes, sterilization can be achieved through a number of different approaches, such…
The latest C Mag-P 3M pumps available from this firm are competitively priced, horizontal sealless pumps with a permanent magnet drive, which makes them suited for transferring corrosive acids and plating solutions in surface treatment and finishing applications. The pump…
A new pump model DB5.5 (photo) has been added to the range of Finish Thompson DP Series of plastic magnetic-drive, sealless centrifugal pumps. This new model DP pump covers flowrates up to 5 m3/h and differential heads of 6.5 m.…
This company has extended its series of dry-running Mink claw vacuum pumps, with a module designed to achieve suction capacities of up to 900 m3/h and more. These Mink MP vacuum modules were designed for applications that require high suction…
High-shear mixers from this company are ideal for challenging mixing operations, such as dispersing gums and thickeners to disintegrate any agglomerates and exposing an increasing surface area of powdered ingredients to the surrounding liquid. The high shearing action of the…
A new range of lift check valves from this company uses a clamp-in-place seat design that allows easy inline maintenance and helps avoid plant downtime. New valve models are constructed using cast iron, carbon steel, stainless steel and SG iron,…
Metcar mechanical seal rings and seal faces are manufactured using highly engineered carbon-graphite materials for demanding high-speed or high-load applications. The seal rings are ideal for sealing liquids, such as water, hot water, acids, alkalis, fuels, heat-transfer fluids, liquefied gases,…
Cellulosic biomass pretreated with ammonia undergoes structural changes that make it more susceptible to enzymatic attack, scientists at Los Alamos National Laboratory (Los Alamos, N.M.; www.lanl.gov) and collaborators at the Great Lakes Bioenergy Research Center (Madison, Wisc.; www.glbrc.org) have found.…
This company’s Type 57IL Isolator Lug butterfly valve features a unique design in which the 316 stainless-steel lugs are inserted into the valve body during the injection-molding process. Doing so permanently combines the lugs and valve body into one unit.…
