Controlling chemical vacuum processes with direct sealing diaphragm valves

The use of vacuum technology for chemical processes has increased dramatically in recent years. Due to the hazards involved with corrosive chemicals, process components must be chemically compatible, as well as extraordinarily accurate and precise. Traditional methods of controlling vacuum are not always suitable, and alternatives–including direct sealing diaphragm valves– must be considered.

Chemical Recovery of γ-Valerolactone/Water Biorefinery

Wood chips have emerged as a suitable biomass to replace fossil fuels and related products; however many technical and environmental complications must be overcome.  This study explores improved methods for a biorefinery used to extract pulp from eucalyptus chips for textile fiber production. Solvent recovery was done via liquid CO2 extraction using the Equilibar BR6 blockage resistant back pressure regulator–designed for supercritical extraction–to control pressure.
