  1. Rohm and Haas Bristol Polymers Polymers Plant Tour Agenda 9/16/2008

  2. Overview • Conference Room & Plant Tour Areas • Tour Safety Discussion • Process Discussion • #7 Kettle Reactor & Charging • #10 Kettle Reactor & Charging • Continuous Reactor Area • Outside Control Room

  3. Tour Safety Discussion • Stick with Team Leader • Working Unit Shut-down/Starting-up • Avoid Contact With Material • Avoid Touching/Operating Equipment • Listen Carefully to Instructions • Observe and Ask Questions

  4. Process Discussion • Solution Polymerization Reactors -- Kettles • Flammability/Toxicity • Monomer/Initiator Reactivity • Heat of Polymerization • Environmental • Operation of Typical Process

  5. Process Discussion • Continuous Reactor Area • Smaller equipment • Possible because of smaller heat of polymerization • Feed of materials • Mixing/dissolving • Polyurethane ingredients • Pressures/temperatures

  6. #7 Kettle Reactor • Relief valves • Rupture Disks • Vent sizing/thrust • Mitigation of relief hazards (modelling indicates evaporates) • Blow-out walls • Classified area • Remote location/cell • Static/grounding/inertion • Process Energy • Fire protection/safety showers/eyewashes

  7. #7 Kettle Charge Area • Ventilation • Floor Loading Access • Material Handling • Ergonomics – valve handle extensions, drum lifter, catalyst hose balancer • Spill control • Open Vessel Mitigation – closed vessels • Labeling • Static/grounding/inertion • Fire protection/safety showers/eyewashes

  8. #10 Kettle Reactor • Relief valves • Rupture Disks • Vent sizing/thrust • Mitigation of relief hazards (modelling indicates evaporates) • Blow-out walls • Classified area • Special maintenance/training/test procedures • Static/grounding/inertion • Process Energy – Kettle is smaller for pressure • Fire protection/safety showers/eyewashes • Pressure operation/access control

  9. #10 Kettle Charge Area • Ventilation • Floor Loading Access • Material Handling/Labeling • Ergonomics – valve handle extensions, drum lifter, catalyst hose balancer • Spill control/cleaning station • Open Vessel Mitigation – closed vessels • Local DCS access • Static/grounding/inertion • Fire protection/safety showers/eyewashes

  10. Continuous Reactor Area • Equipment size/Capacity • Relief • Interlocking/pressure switch • Scale of equipment much smaller • Process intensity • Ventilation • Remote operation, splash hazard for key operation • Fire protection/safety showers/eyewashes

  11. Outside Control Room • Distributed Control Systems – Remote Operation, Alarming, Data • PLC – Programmable Logic Controllers • Local/Hardwire (Relays) • Alarm/Panel alarm • Interlocking • Manually Operated Remote Control • Data Trending & Alarm History • Sequence Operation • Recipe Operation • Standard operation procedures, charge/react/package/integrity

  12. Post Tour Review • Questions • Observations • Thank You for Visiting!!
