DCCP Matrix
| Process Deviation Cause Consequence and Prevention Matrix | |||||||
| Process or Product Name: | Methylcyclopentadienyl Manganese Tricarbonyl (MCMT) Production | Prepared by: | Team 2: Ali Alenezi, Megan Blevins, Reed Boeger, Abigail Doyle | ||||
| Responsible: | Cooling System Point Failure | Process D&C Date (Orig) _____ (Rev) _____________ | |||||
| Process Step / Input | Potential Deviation | Potential Causes | Potential Consequence | Current Preventive Measures | Freq. Of Occurance (1,2,3,4) | Consequence (1,2,3,4) | Recommended Preventive Measures (Where Applicable) |
| What step, equipment, pipe, etc. | List all deviations for the given process step in order to determine best prevention methods in place and needed. | What (list all) could cause the specific deviation? | Impact to employees, equipment, product | Existing Controls in place to prevent deviation? | What else can or should be put in place to prevent deviation? (If the current system is inadequate.) | ||
| Cooling Water System | Insufficient Cooling | water supply valve failure, water drain valve | None: no redundency | ||||
| Metalation/Reactor | Runaway Reaction | Contamination, Concentration mistakes | |||||
| cooling system | cooling system failure | failed pump, fluid leak, fouling, | |||||
| Metalation/Reactor | pressure | improper vent size, improper rupture disk rating | |||||
| Process-Scale Up | pressure valve not sized correctly, hydrogen scale up not calculated. Never increased rupture disk size, hydrogen ignited. Primary cause rupture of big vessel[notes] | ||||||
