Safe, Gas-tight Transfer of Dangerous and/or Expensive Media

The following is a case study presenting the issues encountered and overcome when problem-solving a pyrophoric gas transfer application with KNF customer, Air Products and Chemicals.

INTRODUCTION

Spontaneously-Combustible-SignAir Products is a leading international manufacturer of industrial gases and chemicals. With a staff of over 21,000, the company, based in Pennsylvania, operates in 50 countries across the globe and supplies a wide variety of processing media for myriad applications and industries.

Among goods produced specifically for the semiconductor and solar industry, Air Products manufactures a special gas mixture employed in etching and gas deposition processes to coat silicon wafers and glass substrates; these methods help, for example, to create the active films in flat panel displays and solar cells.

Owing to their pyrophoric properties, the utmost care is required both when manufacturing and using these gases. All system components that store or transfer the gases must therefore prevent air contamination. Should such gases come into contact with air, an exothermic reaction takes place in which a telltale oxidation product is created and deposited in the form of a white coating.

KNF process pumps for hazardous media and environments

KNF N 860.3 FTI Ex – for pyrophoric gas application

In the latest edition of Processing magazine, KNF Process Pump Engineer, Rich Aerts highlights the importance of adapting a diaphragm pump to its operating conditions, media properties, and the needs of the process itself. The article includes a real-life example of pump materials being modified to achieve optimal performance, and illustrates the importance of gas-tightness in the manufacturing of pyrophoric processing gases.
