Construction is underway of a prototype system designed to extract natural bioactive product compounds from plants using supercritical glycerin as the extraction solvent. The initial target for the process is to extract cannabidiol (CBD), tetrahydrocannabinol (THC) and other active compounds…
In order to handle the growing volume of waste textile materials, recycling processes must begin significantly scaling up. Lenzing AG (Lenzing, Austria; www.lenzing.com) and Södra (Växjö, Sweden; www.sodra.com) are joining forces to scale up the OnceMore textile-recycling process, which is…
Although the oceans contain about 5,000 times more lithium than what is found on land, the low concentrations (about 0.2 parts per million (ppm)), as well as the predominance of other larger ions (sodium, magnesium and potassium) makes Li extraction…
Physical adsorption phenomena play a critical role in many separation and purification processes, including separations of industrial gases, purification of gases, moisture removal from fluids, water purification and others. Adsorption is a surface phenomenon in which a fluid (gas or…
The Joukowsky equation is often relied upon to determine the maximum possible fluid pressure inside a pipe, but there are certain scenarios where this equation does not return the expected conservative result for overpressurization We engineers love our formulas. Especially…
The purification of seawater and wastewater for agriculture and human consumption is becoming increasingly important in water-scarce regions. Along with the removal of salt, rendering ocean water and wastewater suitable for humans and plants also involves removal of elements that…
Technologies designed to capture and store CO2 emissions from industrial operations are rapidly gaining traction, but finding ways to economically utilize the captured CO2 has posed challenges. A team of engineers from the University of California Los Angeles’ (UCLA; www.ucla.edu)…
