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…
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…
Plant Watch Chevron upgrades Pasadena refinery to increase capacity and flexibility December 11, 2024 — Chevron Corp. (Houston; www.chevron.com) has completed a retrofit of its petroleum refinery in Pasadena, Texas, which is expected to increase product flexibility and expand the…
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…
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…
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…
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…
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…
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…
Advanced materials are considered to be core enablers for technologies aimed at broad global concerns, such as climate change, sustainable manufacturing, critical-materials supply chains, environmental mitigation and remediation and others [1]. The process by which novel advanced materials are designed…
