A new process for producing lithium titanate oxide (LTO) anode materials could lead to smaller batteries with ultrafast recharging. LTO offers a significantly higher surface area than graphite anode materials, which enables rapid electron transit and, ultimately, much faster recharging…
This column is based on “Bio-Acrylic Acid Production from Glucose – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/acrylic-acid-production-cost. Acrylic acid is a moderately strong carboxylic acid, primarily used in the production of emulsion and…
The following are recently published titles relevant to the chemical process industries (CPI) Sustainable Water Management and Technologies, Vol. 2: Sustainable Water Technologies, By Daniel Chen, Taylor and Francis Group, 2017, 828 pages, $279.95. What Every Engineer Should Know About…
Reliable information about industrial crystallization can be difficult to find and to apply to new situations. The work process outlined here will help engineers approach crystallization challenges Project and plant engineers frequently face issues with crystallization processes, but often possess…
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…
For petroleum refineries, the cost of converting hydrofluoric-acid-based alkylation units to the relatively safer sulfuric-acid-based alkylation process (diagram) has been cost-prohibitive and has lacked specific economic benefits. Now, DuPont (Wilmington, Del.; www.dupont.com) has developed a low-cost approach to converting existing…
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…
Silicon anodes are an attractive alternative to graphite anodes currently in use in lithium-ion batteries, because they can deliver up to five times higher capacities. However, silicon anodes have a limited charge-discharge cycle number. Their volume expands during each cycle,…
Opportunities for improving processes abounded during the first day of the 2017 Chem Show, which opened yesterday at the Javits Center in New York. With a mix of best practice seminars, product presentations and exhibitor booths, the event’s first day…
Chem Show Daily, Tuesday, October 31, 2017 A greater focus on technical education is a major feature of the 2017 version of the Chem Show, which begins today at the Jacob Javits Center in New York City. The 2017 Chem…
