Coupon Cleaning with Gravimetric Analysis

After the contaminant was applied, the coupon was loaded into the preheated autoclave by placing it onto a holder that kept it in a vertical position. The top of the autoclave was then bolted on, and the test started. 

When the autoclave pressure reached 1100 psig, the impeller was turned on to a predetermined speed. The autoclave pressure was 

This indicates that the scaleup process should focus more on flow factors (impeller design, internal reactor geometry, baffling, etc.) than on temperature and pressure in the system.
