Elements and Performance Criteria
- Prepare for work.
- Start-up reaction systems.
- Perform pre-start-up checks
- Start up individual items of equipment and the entire reactor system
- Start up from standby and after maintenance
- Build reaction rate steadily and take appropriate action on deviations
- Stabilise reaction system to produce in specification product at specified rates within minimum time.
- Monitor and control the reaction process.
- Complete routine checks logs and paperwork
- Recognise the signs of potential and actual problems
- Take appropriate action to minimise the impact on safety, health, the environment and the business of potential and actual problems
- Monitor condition of catalyst (if appropriate) and take action to maintain production schedule and quality
- Monitor materials and stock levels of feeds and take action to maintain production schedule and quality
- Trim plant to achieve required rates and quality while maximising plant efficiency.
- Change production rates and/or product grade/specification.
- Predict from rates and schedule when a transition will be required
- Give advanced notice of transition to work team
- Trim plant in a manner which prepares it for the transition
- Manage transitions smoothly and in a timely manner and take appropriate action to achieve this
- Minimise scrap/off grade as a result of a transition.
- Maintain plant effectiveness.
- Frequently and critically monitor all plant throughout shift
- Use measured/indicated data and smell, sight, sound and feel as appropriate to monitor plant
- Identify critical equipment/processes and tune their performance
- Identify issues likely to impact on plant performance and take appropriate action
- Predict impact of a change in one unit/area on other plant units/areas and communicate this to relevant people
- Take appropriate action to maintain plant effectiveness.
- Shut down reaction systems.
- Determine type of shut down required
- Give advance warning of shut down where possible
- Change over individual items of equipment
- Shut down individual items of equipment and the entire reaction system
- Shut down to a stand-by condition if required
- Shut down for maintenance when required.
- Shut down in an emergency when required
- Clean reactors/vessels.
- Isolate and de-isolate reactor.
