Ensure complete discharge from hoppers with this vibrator
The new Vibration Bottom system (photo) enables safe discharge of powdery, crystalline, fatty and granular bulk materials from hoppers. The lateral, imbalance vibrator sets the vibration bottom in horizontal, circular vibration. Vibrations are transmitted to the materials column via the…
Facts at Your Fingertips: Fermentation Considerations and Economics
Producing chemicals and fuels by fermentation of renewable feedstocks can offer improved sustainability, lower costs and greater safety compared to conventional thermal processes. But realizing these benefits depends on a careful assessment of the process economics, and an understanding of…
Technology Profile: Polybutadiene Production via a Solution Process
This column is based on “Polybutadiene Production via Solution Process – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/polybutadiene-production-cost. Polybutadiene (also known as butadiene rubber) is produced from the polymerization of 1,3-butadiene. In terms of…
Efficiency in Pneumatic-Conveying Air Filters
Paying closer attention to the air-filtration systems of pneumatic conveying operations can avoid losses in efficiency in compressed-air usage during filter cleaning The inefficient use of compressed air in solids-handling processes, such as pneumatic conveying, can waste a significant amount…
Valve World Show Preview
The Valve World Americas Expo and Conference (www.valveworldexpoamericas.com) will take place at the George R. Brown Convention Center in Houston (June 19–20, 2019). Organized by KCI World and Messe Düsseldorf North America, the 2019 edition of the bi-annual event will…
Technologies for Controlling H2S
There are many industrial technologies for removing H 2 S from process gas, and each brings with it different benefits with regard to costs, efficiency and equipment layout Hydrogen sulfide (H2S) is a toxic and corrosive gas that occurs naturally,…
Professional Calibration Supports Operational Excellence
Apart from ensuring the conformity of the process and the quality of the product, professional calibration, first and foremost, improves the quality of the process At many plants in the chemical process industries (CPI), measurement instrumentation is usually calibrated during…
Minimizing Risk for Combustible Dust Explosions
By focusing on ignition sources, such as static discharges, and housekeeping, facilities handling solids can minimize their risk for combustible dust explosions Dust explosions in industrial facilities can cause injuries, destruction of property, and — as history will attest —…
Siemens to supply compressors to gas plants in Delaware Basin
Siemens AG (Munich, Germany; www.siemens.com) was recently awarded a contract to provide three residue compression trains for two, 250-million (500 million total) standard cubic feet per day (MMSCFD) cryogenic gas plants in the Delaware Basin. The customer, a key producer…
Minimizing Corrosion with Fast, Robust Gas Analysis
Corrosion can never be totally stopped, but significantly slowing its progress can be achieved if analyzers rapidly detect out-of-spec conditions. For a prominent European chemical company, switching from slow electrolytic sensors to almost real-time moisture analysis has made a significant…
