Case Study: HELP ! We Can't Make Product!

This customer had severe problems with a pilot plant that was holding up a $200 million dollar expansion and a whole new way to make nylon.

Product   Nylon
Location   East Texas
Situation   A large chemical manufacturer was in a bad situation.  Their pilot facility was evaluating the feasibility of a whole new way to make nylon, before a $200 million expansion.   A tricky little mysterious quality problem stood in their way:  Every so often, the product failed,... miserably, completely.  These events were blocking the customer from moving forward into full production.  Their best chemists, engineers, statisticians and lab researchers slaved to save the project, their multi-million dollar pilot investment and the large capital roll-out, but without success.  Our mission was to determine the cause of these events.
Objective  

Find and resolve the cause of the barrier to produce.

 

Method   BioComp engineers came on site and teamed up with the Customer's process experts.  A box was drawn around the portion of the process where the problem was occurring.  Flows of materials, process control points and information in and out of this box were identified, much like a mass and energy balance.  Data was collected on these attributes from the local process and quality management systems.  This data was modeled using BioComp's iUnderstand analysis tool to find the key drivers of "Problem" vs. "No Problem".
Result   The iUnderstand analysis quickly pointed towards the catalyst composition as containing the cause, quickly eliminating all other process flows, operating conditions and other materials streams.  Further modeling was performed, specifically targeting the components (ingredients) of the catalyst.  Key "contaminants" (catalyst decomposition products) were identified as the likely cause.  Specific concentrations were calculated that would likely cause the problem.  A process change recommendation was made and the problem was eliminated.
