PS Recycling INEOS Styrolution America LLC (Aurora, Ill.; www.ineos-styrolution.com) and Agilyx ASA (Oslo, Norway; www.agilyx.com) are advancing the development of a previously announced 100-ton/d TruStyrenyx chemical-recycling facility in Channahon, Illinois. TruStyrenyx is a partnership between Agilyx and Technip Energies N.V.…
In synthesizing a new molecule that mimics the nickel-iron (NiFe) hydrogenase enzyme, a team of researchers from University of Illinois Urbana-Champaign (www.illinois.edu) may have uncovered a promising alternative to the platinum-based catalysts typically used in the electrolysis of water to…
Membrane filtration plants are often used in the food and dairy industry to separate or concentrate substances without thermal stress. Until now, cleaning-in-place (CIP) operations for this equipment was energy- and water-intensive, requiring three or four individual cleaning steps with…
Plant Watch Evonik plans to double global PEBA production capacity April 14, 2023 — Evonik Industries AG (Essen, Germany; www.evonik.com) is doubling its global capacity for polyether block amide (PEBA) with a twofold approach, including a major expansion of its…
The gas subcooled process (GSP) is a method for low-temperature separation of natural-gas liquids (ethane, propane) from natural gas. Depending on the current market prices of ethane and propane, gas processors extract ethane from the natural gas or reject it…
A newly developed hydrogen compressor has a linear motor design and is hermetically sealed to increase the efficiency of H2 compression while avoiding potential problems associated with H2, such as leaks and embrittlement. The linear motor-driven reciprocating compressor (LMRC), developed…
Solvents are commonly used for performing photochemical reactions. Many of these solvents are toxic, and require additional downstream processing to purify the product and treat waste. Now, by combining light with mechanical energy in ball mills, researchers at Ruhr University…
As process technologies — and their associated risks to workers — evolve, personal protective equipment must continue to push the boundaries in both functionality and comfort Personal protective equipment (PPE) — helmets, fire-resistant clothing, gloves, goggles and so on —…
Chemical recycling of waste polyolefins is difficult to achieve economically partly because of the stability of carbon-carbon bonds in the plastics. In a new approach, researchers at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) and the Technical University of…
Current electrolyzers for producing hydrogen use purified water as feedstock, but in the future, this could exacerbate freshwater shortages in some areas. Seawater is highly abundant, but the ions it contains undergo electrode side reactions, and cause corrosion in proton-exchange…
