Copper and cadmium exist naturally in the environment, but human activity can increase their concentrations to a point where they become a health hazard. Conventional wastewater treatment to remove those metals includes chemical precipitation, coagulation, flocculation, ion exchange, membrane filtration,…
At the end of last year, Mino Ceramics Co. (Nagoya City, Japan; www.mino-ceramic.co.jp) began shipping its first commercial high-temperature heat exchangers, which were developed in a project by Thermal Management Materials and Technology Research Assn. (TherMAT, Tokyo, Japan; www.thermat.jp). Developed…
Consisting of a land-based mechanical facility and underwater pipelines and accumulators, the underwater compressed-air energy-storage (UCAES) system from Hydrostor Inc. (Toronto, Ont., Canada; www.hydrostor.ca) takes electricity (potentially excess solar or wind energy) and uses it to run a compressor, which…
The recently commercialized high-speed turbo (HST) compressors from BOGE Kompressoren Otto Boge GmbH & Co. KG (BOGE; Bielefield, Germany; www.boge.de) produce 100% oil-free (Class 0) compressed air at the highest degree of efficiency and with minimal maintenance effort, according to…
There are many critical parameters that are important to monitor and measure in industrial polymer reactions, including molecular weight, viscosity and residual monomer concentration. Typically, polymer reactions are characterized offline and intermittently in a quality-control laboratory, or via inferential models…
Early this year, Lanxess AG (Cologne, Germany; www.lanxess.com) will start production of bright red iron-oxide pigments at its Ningbo, China production site. The production facility will utilize — for the first time — the Ningbo Process, a highly sustainable production…
Automobile catalytic converters contain cerium-based co-catalysts to enhance the overall effectiveness of the converter by absorbing and releasing oxygen to convert CO into CO2. Existing emission control systems typically use CeO2-based materials, such as solid solutions of ceria and zirconia,…
PET recycling Polyethylene terephthalate (PET) can be quickly depolymerized into virgin monomers using a patented process that was developed, and is being scaled up by Ioniqa Technologies BV (Eindhoven, the Netherlands; www.ioniqa.com). The company recently finalized a multi-million-euro funding round…
Increased use of ethane from shale deposits as a feedstock for ethylene production has focused attention on the growing need for on-purpose production of butadiene, which has traditionally been produced primarily as a byproduct of conventional ethylene production from naphtha.…
Scientists from Yonsei University (Seoul, South Korea; www.yonsei.ac.kr) led by Prof Eunkyoung Kim, have developed a hybrid solar cell to enhance the photo-conversion efficiency of a solar cell with a thermoelectric device operated by photothermally generated heat. The efficiency was…
