1960s Scientific Diagram, Fig 2: Typical Claus Sulfur Plant Mounted in Window Mat, Free U.S. Shipping

We got our hands on a stash of mid century scientific diagrams from the archives of the Griffith Observatory, Los Angeles. Figure 2, pictured here, breaks down "Typical Two-Stage Claus Sulfur Plant." Don't ask us to explain what on earth that means (something to do with recovering elemental sulfur from gaseous hydrogen sulfide?...), but we sure think it's a neat vintage print.

Newly mounted in a custom acid-free overlay window mat and protective plastic sleeve. The print is c. 1960s vintage; it's in very good/excellent condition.

Dimensions:
Image size- 10.5" x 8" each window
Over mat size- 16" w x 20" h
