Taming Static Electricity in Glass-Lined Reactors

Process Safety with Trish & Traci

On a sunny summer day in 2007 near Wichita, Kansas, a tanker truck was offloading naphthalene into a stainless-steel tank at a solvent tank farm when the container spontaneously ignited, catching fire and exploding, shooting projectiles in the air.
