The plant ran with difficulty; lots of big shutdown problems and the process fume destroyed the local environment; all of this would have been discovered and remedied if they had piloted the project, but pilot was eliminated as a "money saving" step which cost more in capital replacement and operational down time than the pilot plant would have.
