Separating recyclables from our trash has become commonplace for many of us. What can be recycled and how it is collected, however, varies quite a bit by location. My town, for example, accepts plastics #1 (polyethylene terephthalate; PET), #2 (high-density…
Commissioning is wrapping up this month for a pilot facility designed to validate the capabilities of a new carbon-capture solvent. The pilot plant was constructed by Koch Modular Process Systems (KMPS; Paramus, N.J.; www.kochmodular.com) as part of Project Enterprise, a…
Traditional vapor-compression refrigeration relies on hydrofluorocarbons (HFCs) as refrigerant fluids — a class of compounds with global-warming potentials (GWP) thousands of times higher than that of CO2. A new approach from scientists at Lawrence Berkeley National Laboratory (LBL; Berkeley, Calif.;…
Metso Corp. (Helsinki, Finland; www.metso.com) has optimized its existing rotary kiln technology and launched RotarEkiln, an electrically powered, indirectly heated rotary kiln. The electric heating system of the RotarEkiln provides a sustainable alternative to conventional fuel-powered indirect rotary kilns. The…
Plant Watch Mitsui Chemicals to increase production capacity for polyurethane dispersions August 11, 2023 — Mitsui Chemicals, Inc. (Tokyo, Japan; www.mitsuichemicals.com) will increase its production capacity for polyurethane dispersions (PUDs) at the company’s Shimizu site. This expansion will approximately double…
Discovering new catalysts and materials for specific applications can be a tedious and time-consuming process involving labor-intensive tests and expensive samples. Technology developed by Mattiq (Skokie, Ill.; www.mattiq.com) enables the “printing” of tens of thousands of tiny material samples onto…
Follow these nine recommendations to establish a strong program for preventive maintenance of rotary drums in drying, cooling and other treatments of bulk solids Maximizing efficiency is increasingly a critical priority for plant managers, leading many to move away from…
On-point configuration for all requirements With the new Flender One platform, this company’s engineers have developed the world’s narrowest gear-ratio range, with 103 stages between 1 and 7.1 per size for applications that require particularly precise speed, such as pumps…
With global temperatures likely to rise beyond the 1.5°C target set by climate experts, negative emissions technologies — most notably direct air capture (DAC) — become increasingly important for addressing CO2 already in the atmosphere. A new DAC approach is…
Ammonia is becoming more crucial for the energy transition as renewable-power producers look to its potential as a means for energy storage. Typically made using the energy-intensive Haber Bosch (HB) process, solutions for decarbonizing NH3 typically involve the adoption of…
