Ion-exchange beads for lithium extraction

With lithium demand higher than ever, processors are increasingly turning toward emerging technologies and new resources for lithium extraction. A new California-based project launched by Controlled Thermal Resources (CTR; Imperial, Calif.; www.cthermal.com) and Lilac Solutions (Oakland, Calif.; www.lilacsolutions.com) aims to…

MOFs and nanochannels enable lithium extraction from brines

Lithium is a key raw material for batteries that power electric vehicles, portable electronics and more, but traditional methods for obtaining it are plagued by poor lithium recovery (a large portion of Li is lost in the recovery process), slow…

Facts at your Fingertips: Nucleation Phenomena in Crystallization

Industrial crystallization processes are widely used in the chemical process industries (CPI) for their ability to separate and purify products in a single step, often to greater than 99.9% purity. Crystal growth proceeds after nucleation, a molecular aggregation process whereby…

Facts at your Fingertips: Distillation Trays and Packing

Industrial distillation columns use either trays or packing to promote vapor-liquid contact in separating the components of liquid mixtures to the desired purity. Approximately one half of columns are equipped with trays globally, and the other half contain packings. This…

Facts at your Fingertips: Centrifuge Separation Capacity

This one-page reference describes how to measure the capability of a given centrifuge to separate solids from a liquid phase. G-force The centrifugal force developed by a centrifuge is expressed as a multiple of the force of gravity. This force,…
