Improve Ethylene Production Margins with Digitalization
Digitalization can help ethylene producers to flexibly respond to economic uncertainties and assess available options based on their existing infrastructure and priorities Post-pandemic, olefin and polyolefin producers have been faced with regional and global economic headwinds. Inflation, energy security, rising…
Entrainment Flooding and Weeping Velocities
Weeping and flooding phenomena set the vapor velocity in industrial distillation columns. Presented here are procedures for calculating flooding and weeping velocities in a four-pass sieve-tray column In industrial distillation, the term “weeping” is primarily used when the liquid in…
CPI Outlook for 2025
The industrial sector consumes more than 80% of basic and specialty chemicals. Worldwide, industrial activity saw a modest recovery in 2024. Global industrial production is expected to have increased by 1.3% by the end of 2024, with predictions of about…
Electrically powered heat pumps and vacuum pumps simplify CO2-capture retrofits
Meeting climate-change goals requires steep reductions in greenhouse-gas emissions from existing power plants and hard-to-abate industry operations. However, the energy required to release captured CO2 from sorbent material is a challenge for the economic viability of these efforts. Also, retrofitting…
Safeguarding the Hydrogen Economy: A Focus on Leak Detection and Mitigation
The use of fixed gas detectors can play a crucial role in mitigating the environmental impact of hydrogen leakage and help protect workers in the hydrogen value chain Governments, industry sectors and companies seeking sustainable energy sources to reduce greenhouse…
Confined-channel membrane architecture allows simultaneous oil and water recovery
Surfactants can stabilize oil and water in an emulsion, a useful mechanism in many industrial processes and in cleaning up oil spills. But separating and recovering the oil and water, such as for eliminating waste discharge, can be difficult. A…
Rational synthesis techniques lead to improved catalyst for dry methane reforming
Dry reforming of methane (DRM), in which carbon dioxide and methane are combined to form synthesis gas (H2 and CO), is an attractive route to making syngas because it does not require consumption of water and does not produce CO2…
Single-atom catalysis reduces water-splitting costs
One of the main limiting factors in the production of “green” hydrogen via electrochemical water splitting is the relatively slow rate of the oxygen evolution reaction (OER) and the use of very expensive noble metals like iridium to catalyze the…
Toray to build gigawatt-class mass-production system for water electrolyzer materials
Toray Industries, Inc. (Tokyo) announced that the Ministry of Economy, Trade and Industry has selected the company’s project to build a gigawatt-class mass production system for electrolyte membranes used in water electrolyzer for the Green Transformation Supply Chain Development Support…
Mitsubishi Power Americas and Pacific Northwest Hydrogen Association formalize partnership to advance hydrogen hub projects
Mitsubishi Power Americas, through its subsidiary MHI Hydrogen Infrastructure (MHI H2I), announces the recent signing of a subrecipient agreement between the Pacific Northwest Hydrogen Association (PNWH2) and MHI H2I’s Boardman Hydrogen Hub project. The PNWH2 Hub, one of the country’s…
