Thanks to Caitlin Wood for collecting and organizing the data that was collected during the experiments. Thanks to Tom White and Steve Crump of SRNL Analytical Development for analyzing the blended condensate samples to determine the concentrations of HMDSO, TMS and propanal. Thanks to Alex Nikolov and Darsh Wasan, inventors of the Antifoam 747, for advice and support during this testing. Thanks to Isaac Bodey for the prompt delivery of Antifoam 747 pails as needed for testing. Thanks to Momentive for supplying a sample of Silwet L-77.

Nd is calculated from the sum of masses 143-146, 148, and 150; Ru is calculated by summing masses 101, 102, and 104; Rh is determined from mass 103; Pd is calculated from mass 105 and fission yields; Th is determined from mass 232; and U is calculated from the sum of masses 233 to 236 and 238. ‡ RSD = relative standard deviation; n = number of replicates. NA = not applicable.
