Phase B was intended to demonstrate the inherent process reliability. In other words, this phase
was intended to demonstrate how repeatable and reliable at scale the process technology might
be; also developed was information necessary for the design of a commercial facility. Phase B
intended to use the same KPI's, but the objective was to perform extended performance runs,
similar to that seen in commercial scale facilities, with the goal of understanding how often over
the course of the performance run was the process successful in attaining each KPI. Phase B was
expected to take place in the three month period from October 2009 through December 2009.
Actual Results
The results of Phase A were largely attained, but not completed. Further, there were both
schedule and cost over-runs incurred during the Phase A demonstration period. Results for
Phase A through May 2010 are summarized in the chart below. Color codes indicate the success
or failure of attaining the KPI.
" Red indicates Under-performance
" Gold indicates Sub-Optimal performance
" Green indicates Optimal-performance

Data Analysis
Feedstock Moisture
During the course of the project, the metric "Incoming feedstock moisture" was tracked for two
reasons: downstream process control and overall process water mass balance. In the initial
stages of the project, the incoming feedstock had moisture contents in excess of 10% over target
specifications. Downstream unit operations were effected, and process modifications were made
to adjust for variations in moisture content until a capital project could be put in place to dewater
the feedstock feeding the hydrolyzer to meet specification. Later in the project (May-10, Jun-
