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
