A line of low internal volume heaters is suited for use in ultra-high purity (UHP) solvent-heating applications in semiconductor manufacturing, including wafer cleaning, etching and photoresist-stripping processes.
The BSA and A3S isolation valves are engineered to maintain plant safety and save energy by eliminating stem seal leaks. The valves can help oil, gas, petrochemical, pharmaceutical, food and beverage facilities reduce energy use and ensure operator and plant safety.
A 1200-gal metal dryer that became overpressurized during a chemical product drying operation is the cause of an explosion and fire at the Optima Belle Chemical LLC facility located in Belle W.V., on December 8.
Impedance pipe heating is a long-established and accepted — but poorly understood — pipe heating technology. While a simple and elegant way to heat a pipeline, impedance pipe heating technology often is viewed incorrectly and misunderstood as a method to heat process piping.
Safety oven designs — standard Class A, low oxygen Class A and explosionproof — incorporate specific components and heating methods to inhibit unintended combustion reactions. Aside from components, one of the biggest differences is how they approach the fire triangle.
Many processes involve the heating of volatile, flammable solvents, and these require some type of safety oven to mitigate the risk of a fire or explosion. These ovens fall roughly into three categories, depending on which side of the fire triangle they address.
When selecting a safety control system for a combustion application, it is essential to recognize that many trade-offs will need to be weighed before making a decision. In simple terms, the reliability will decrease when adding safety to any system.
The spectrum of applications found in the process industries means that burner designs must vary widely. Smaller burners are utilized in paint booths, ovens and furnaces while larger burners are specified for incinerators, thermal oil heaters and oxidizers.
