New microreactors and flow loops improve asphaltene management

Asphaltenes are an ultra-complex fraction of crude petroleum that comprise a diverse population of molecules that vary in size, solubilities, aggregation states and hetero-atom contents. Asphaltene buildup and deposits create many operational and safety issues, and can occur anywhere in…

Next-generation encapsulation technology

Nucleic acid-based medications, such as mRNA vaccines, are opening up new therapeutic approaches. These active ingredients must be enclosed inside nanoparticles to ensure that they get to where they are needed inside the body’s cells. The Fraunhofer Institute for Production…

Extracting useful proteins from beer-brewing leftovers

Brewers’ spent grain (BSG) is the most significant byproduct of the beer-brewing industry, making up 85% of the total waste. Globally, about 36.4 million ton/yr of spent grain are produced. This spent grain is typically discarded after its primary use…

Advanced Column Internals Support Energy Efficiency

New packings and trays encourage effectiveness and energy efficiency in traditional and emerging applications Equipment for distillation, absorption, stripping, extraction and phase separation plays a major role in the chemical process industries (CPI). However, separation processes are notoriously energy intensive,…

Facts At Your Fingertips: Cooling Tower Basics

Most modern chemical processes require some means of rejecting heat for maintaining process efficiency, product quality and plant safety. Examples of heat rejection include cooling crystallization liquid, cooling reactor effluent, condensing material from a distillation column and cooling steps in…

Golden Rules of Electrical Temperature Measurement

Understand and follow these tips to ensure accurate and reliable temperature values Even though electrical thermometers are used quite frequently in chemical process industries (CPI) plants, people often underestimate just how wrong the temperature displayed can be if these measurements…
