Rohm and Haas Bristol Polymers

Polymers Plant Tour

Agenda

9/16/2008


Overview

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


Tour safety discussion

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


Process discussion

Process Discussion

  • Solution Polymerization Reactors -- Kettles

  • Flammability/Toxicity

  • Monomer/Initiator Reactivity

  • Heat of Polymerization

  • Environmental

  • Operation of Typical Process


Process discussion1

Process Discussion

  • Continuous Reactor Area

  • Smaller equipment

  • Possible because of smaller heat of polymerization

  • Feed of materials

  • Mixing/dissolving

  • Polyurethane ingredients

  • Pressures/temperatures


7 kettle reactor

#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 kettle charge area

#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


10 kettle reactor

#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


10 kettle charge area

#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


Continuous reactor area

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


Outside control room

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
