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…
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…
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…
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,…
The following are selected recently published books that may be relevant for chemical process industries (CPI) professionals Dispelling Chemical Engineering Myths, 3rd ed. (electronic book edition). By Trevor Kletz, CRC Press, 2019, $57.95, e-book. Guide for Making Acute Risk Decisions.…
Controlling and reducing particulate matter pollution from industrial operations is a key environmental and human health objective. In chemical process industries (CPI) facilities, airborne particulate matter can result from combustion of fuels, or from process operations, such as dust from…
The winning technology for the 2019 Kirkpatrick Chemical Engineering Achievement Award, along with the other finalist technologies, demonstrate how innovative engineering can tackle climate change and other challenges. All six technologies are described here The six finalist technologies for the…
This article provides an overview of how computational fluid dynamics (CFD) works, and what benefits it can bring to the chemical process industries Sustainability, waste reduction, energy efficiency and increased demand for engineered material are driving process engineers to continuously…
Vacuum drum filters are state-of-the-art in highly corrosive applications like producing titaniumdioxyd (TiO2) in sulfuric acid (H2SO4) processes or in processes where slurries with a high content of hydrochlorid acid (HCl) are used. Conventionally, these filters are made out of…
You have to spend money to make money. Never has the old adage been truer than in today’s world of Industry 4.0, smart engineering advances, and fiercely competitive markets. In the past, to achieve high-quality separation and high purity of…
