ExperTune Announces ProcessApex(TM), to Improve Process Units and Plant Operations


ExperTune announces ProcessApex(TM), providing real-time advice for process unit operations, based on
the expert advice of Greg Shinskey and others. This system builds on the success of ExperTune's
PlantTriage system, delivering specific diagnostics, advice, and improvement suggestions for process unit
operations. Further, it allows direct benchmark comparisons between unit operations across an entire
company. This data drives daily decisions to improve plant operations, as well as high-level decisions
such as capital spending, at the corporate level.

"Plants are awash in real-time data. With ProcessApex(TM), we automatically provide context to real-time
data, and combine it with embedded engineering expertise. The result is some very concentrated, very
powerful information. Each unit operation becomes a 'smart' unit operation, capable of self-diagnosis and
self-improvement." says John Gerry, President and Founder of ExperTune, Inc.

ProcessApex(TM) technology handles unit operations from simple to complex. Individual process objects
include common operations such as heat exchangers, dryers, and even distillation columns. Each
'Smart' unit operation provides real-time performance metrics appropriate to that unit. The performance
metrics address throughput, quality, reliability, and cost. A direct link with ExperTune's PlantTriage
system allows users to drill down into specific performance issues.

Benchmarking tools help users to squeeze additional value from process performance information. This
includes tools for benchmarking within and between similar unit operations over time. When used at a
corporate level, the tools can help drive capital spending decisions, resolving questions like "Where
should I add more production capacity?" With its benchmark perspective on cost, efficiency, and excess
capacity, ProcessApex can provide a very specific answer to this question.

Mr. Gerry continues, "Smart instruments revolutionized the maintenance world. The smart unit op will
revolutionize the entire business of process plant manufacturing...from the plant floor to the boardroom"
