On this episode of the Chemical Engineering podcast, our guest is Moe Tanabian, the chief product officer at industrial software company Cognite. We talk with Moe about the potential of artificial intelligence-powered large language models (LLMs) to significantly enhance business…
Hydrogen Production via Methane Pyrolysis: An Overview of ‘Turquoise’ Hydrogen
‘Turquoise’ hydrogen processes generate H2 without releasing CO2. Presented here are the opportunities and challenges for producing hydrogen by methane pyrolysis Hydrogen-producing processes are classified using a color scheme according to their carbon footprint (Table 1; [1–3]). So-called “turquoise hydrogen”…
The first H2-fired low-NOx burner for traveling-grate pelletizing plants
Last month, Metso Corp. (Espoo, Finland; www.mogroup.com) introduced a hydrogen-variant of its Ferroflame LowNOx burners as part of its NextGen Pelletizing plant product range. It is a first-of-its-kind burner to run on H2 and to operate on the LowNOx combustion…
Facts At Your Fingertips: Wet and Dry Milling
Milling is a common technique for controlling particle-size distribution (PSD) in solid products through size reduction and surface modification. Broadly, mills can be categorized as wet or dry mills, and these two categories are each further subdivided by how comminution…
Modular Construction Encourages New Applications
The efficiency and cost effectiveness of modularity provides advantages for small- and large-scale projects When the right conditions exist, the benefits of modular construction — from laboratory scale to large scale — are plentiful and allow single-source, cost-effective and efficient…
Closed-loop CO2-based energy-storage system slated for Wisconsin
Alliant Energy (Madison, Wis.; www.alliantenergy.com) was recently selected to receive a $30-million grant from the U.S. Dept. of Energy’s Office of Clean Energy Demonstrations (OCED; Washington, D.C.; www.energy.gov/oced) for a proposed 200-MWh energy storage system. Alliant Energy’s new battery system,…
Management and Maintenance Strategies for Valves
Asset criticality and risk are primary among the many factors that must be considered to appropriately manage valves throughout their lifecycle Asset strategies usually define how assets will be treated in the different phases of an asset lifecycle, from acquisition…
Solids Flow Measurement in Specialty Chemicals: Seamless Integration
Continuous flow measurement is used at this Austrian specialty chemicals manufacturer for process optimization, as well as overload protection Sensing-plate weighing systems are often used for weighing free-flowing and very dusty bulk materials. Such solids flowmeters ensure reliable determination of…
Commercial Progress on Turquoise Hydrogen
Producing hydrogen via methane pyrolysis – termed ‘turquoise hydrogen’ – has thus far received less attention than ‘blue’ and ‘green’ H2, but it may offer advantages over both While the vast majority of current hydrogen production occurs by steam reforming…
