Soil bacteria that oxidize methane (methanotrophs) are important in capturing methane before it enters the atmosphere. Now an international team has isolated and characterized methanotrophic bacteria — obtained from a New Zealand volcanic field — that can grow on CH4…
Chemists and engineers from the Performance Materials Segment of Evonik Industries AG (Essen, Germany; www.evonik.com) have developed a new process for making methyl methacrylate (MMA). With a yield of over 90%, the so-called Leading in Methacrylates (LiMA) process can be…
The XperLUBE system (photo) uses automotive-style solenoid injectors to deliver lubricant in precise quantities. Unlike traditional lubrication devices, XperLUBE integrates fully with modern control systems and adapts to changes in operating conditions. A key feature is the way each injector…
This company has fabricated a 300-gal vessel (photo) designed for 5 psi internal pressure at 300°F. All of the wetted surfaces are stainless-steel type 304L polished to 240-grit finish. The vessel is agitated by a special disperser blade driven to…
The new bag-in-bag system quickly and reliably packs filled paper bags individually or in groups with a weather-resistant plastic film (photo). This protects the contents against moisture, dust, insects and other environmental influences during storage and transport. The bag-in-bag is…
Cake filtration is a common operation across many sectors of the chemical process industries (CPI). In cake filtration, the solid being filtered acts as a screen so that particles of the suspension are retained by the medium, resulting in the…
This column is based on “Calcium Hypochlorite Production via Sodium Method – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/calcium-hypochlorite-production-cost. Calcium hypochlorite, Ca(OCl)2, is among the few metal hypochlorites that is stable enough to be…
The CoriMix continuous-ring layer mixer (photo) a features a ring layer system that rotates with circumferential speeds of up to 40 m/s. As a result, the product components are accelerated through centrifugal force. This causes a ring layer to be…
These lidded drums (photo) are dull TIG (tungsten-inert gas) welded with welding filler material and without gaps. The seams are rolled flat and finely polished inside and out. The drums are also easy to clean and residue-free, and have a…
The E9000 emissions analyzer (photo) features a heated sample line and is suitable for regulatory and maintenance use in boiler, burner, engine, turbine, furnace and other combustion applications. The analyzer can accommodate up to nine total gas sensors, including electrochemical…
