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…
‘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”…
Overpressure protection is at the center of process safety across all chemical processing sectors. As processes and technologies evolve, it is essential that safety systems can adapt to provide the utmost levels of protection All over the chemical process industries…
Flange-bolted joints enable connections of singular segments of pipes into more complex sections, as well as joining measuring and process devices, such as flowmeters, pumps, fans and pressure vessels. These joints are potential sources of leakage, which can introduce safety…
Separating recyclables from our trash has become commonplace for many of us. What can be recycled and how it is collected, however, varies quite a bit by location. My town, for example, accepts plastics #1 (polyethylene terephthalate; PET), #2 (high-density…
Facilities can reduce emissions without major capital projects. Here are some practical ideas showing where to start People working in the air-pollution control industry used to boast that you can remove everything from fluegas except carbon dioxide, and it remains…
There are several established technologies to remove per- and polyfluoroalkyl substances (PFAS) from water, including membranes and adsorbents. However, such purification media can pose disposal challenges due to the potential for further PFAS contamination stemming from the spent media. Now,…
One of the major byproducts of the nuclear fission process used for power generation is 137Cs, a radioactive isotope of Cs that has a half-life of 30 years and is often removed from nuclear-power-plant wastewater via selective adsorption using ion…
It is well known that mercury is not only toxic, but is also highly mobile. As a result, Hg emissions from both industrial processes (gold mining, combustion of fossil fuels, cement production, waste incineration and more), as well as natural…
Chemical plants should not overlook the potential problems that can arise from damaged or malfunctioning lighting fixtures It is no secret that many chemical plants and industrial sites are prone to harsh environmental conditions that can wreak havoc on equipment…
