Using halide perovskites for photovoltaic (PV) solar-energy cells could dramatically reduce production costs compared to silicon-based PV cells, because perovskites are solution-processible at relatively low temperatures. However, long-term stability of these materials has been a significant challenge. Now, a research…
Methane pyrolysis catalyst Catalytic methane pyrolysis (CMP) is an attractive route to producing hydrogen, because rather than generating CO2, the process produces solid carbon, which can be made in valuable forms that could offset the cost of hydrogen production. However,…
Plasma technology is being explored as an avenue for many molecular conversions, such as methane reforming. Now, for the first time, a plasma-based CO2-conversion technology is being demonstrated industrially. The proprietary technology, developed by D-CRBN (Antwerp, Belgium; www.d-crbn.com), is being…
The flat-edge spiral-screw conveyor design (photo) features a broad, flat edge that minimizes the potential for aeration to add volume to low-bulk-density materials during transfer. Offered with the company’s Spiralfeeder flexible-screw conveyor, the new design is suitable for transferring cake…
Electrolyzers are the key technology for producing “green” hydrogen using renewable energy. However, a new reactor platform aims to facilitate electrolysis without the need for any external electricity. The Electroless Coupled Exchange Reduction Oxidation technology platform (eXERO), developed by Utility…
Plant Watch Sika more than doubles capacity at its largest manufacturing plant in Indonesia August 13, 2024 — Sika AG (Baar, Switzerland; www.sika.com) has more than doubled the production capacity at the Bekasi plant, its largest manufacturing facility in Indonesia.…
This three-way ball sector valve (photo) — said to be the world’s first — achieves high volumetric flowrates that are virtually identical in all directions. The company’s approach of using the ball sector design for three-way valves is said to…
Managing wastewater at chemical process industries (CPI) facilities requires a tailored approach, and effective treatment promotes sustainable operations while avoiding potential regulatory penalties For many consumers and businesses, wastewater simply disappears down the drain and out of sight. However, for…
Any loss of containment for liquefied petroleum gas (LPG) can have potentially catastrophic results. This article details various LPG storage configurations with special focus on the design of mounded-bullet systems Liquefied petroleum gas (LPG) is a mixture of propane and…
Freeflex Versa (photo) compressor-valve steel is a new material that contributes to designing smaller, more sustainable and more energy-efficient compressors for refrigerators and freezers. Building upon the success of its predecessors Hiflex and Freeflex Core, this martensitic stainless steel is…
