New solvents derived from biomass
Last month, Circa Group A/S (Oslo, Norway; www.circa-group.com) applied for patents for two new solvents for CO2 capture processes. The solvents, named Furatech:1 and Furatech:2, were developed over the last 12 months as part of the company’s platform molecule, levoglucosenone…
Observing particle concentrations and velocities inside a fluidized bed
Fluidized beds are used in a variety of industries for combustion, drying, catalytic cracking and other processes. However, the process that occurs inside a fluidized bed is extremely complex and — due to a lack of effective measurement techniques —…
Chementator briefs
ISOPROPANOL Cepsa Química, S.A. (Palos de la Frontera, Huelva, Spain; www.cepsa.com) is constructing the first production plant to produce isopropyl alcohol (isopropanol), from renewable or circular materials, which the company says will make it the most competitive, innovative and environmentally…
This fiber technology could revolutionize building construction
With the Texoversum (photo), Reutlingen University (Germany; www.reutlingen-university.de) has put into operation a training and innovation center for the textile industry that is unique in Europe. The almost 2,000-m2 textile-like façade of the new building combines the innovative power of…
Electrochemical amalgamation effectively removes mercury from concentrated H2SO4
It is well known that mercury is not only toxic, but is also highly mobile. As a result, Hg emissions from both industrial processes (gold mining, combustion of fossil fuels, cement production, waste incineration and more), as well as natural…
Carbon nanotube coating could expand the applications for superlubricity
When a sliding interface experiences a coefficient of friction (CoF) below 0.01, the situation is said to have superlubricity. In the past, superlubricity has been limited to the microscale in controlled environments, and to ceramic surfaces with polar-fluid lubrication. Now,…
Focus on Analyzers
A self-calibrating process-development Raman system The PTRam analyzer (photo) is a high-performance, precise, rugged and reliable Raman system featuring self-calibration and automated performance validation to ensure validity of every measurement. The system features long-lasting laser stability for consistent results, a…
New adsorbent removes radioactive cesium ions from nuclear wastewater
One of the major byproducts of the nuclear fission process used for power generation is 137Cs, a radioactive isotope of Cs that has a half-life of 30 years and is often removed from nuclear-power-plant wastewater via selective adsorption using ion…
Tower Doctor: Can the Cure be as Bad as the Illness?
Henry Kister shares lessons learned from troubleshooting distillation towers During a course that I was presenting in Houston one year, a participant asked me the following at the end of one of the sessions: “Do you have experience with BX-type…
Materials of Construction for the CPI
The proper selection of materials of construction is crucial. The example presented here shows how to use standards to help narrow down the options Since the late 1800s, a steady body of pressure technology codes and standards have been under…
