A solvent-extraction approach for desalination of high-salinity brines
Hypersaline industrial wastewater brines are difficult to treat. Current approaches for removing salt from such brines — such as evaporative distillation and reverse-osmosis (RO) — are problematic because evaporation is highly energy-intensive and RO cannot handle salt levels present in…
Increasing the Reliability of Valves Through Design
The latest valves are designed to last in challenging chemical applications, increasing uptime and safety As operational efficiency and safety continue to be top priorities in the chemical process industries (CPI), processors are demanding increased reliability from their equipment, and…
