Elements and Performance Criteria
- Prepare for work.
- Start up distillation system.
- Perform pre-start up checks
- Bring into operation equipment required for distillation
- Correctly sequence all equipment required before commencing the process
- Monitor temperature increase during start up and take appropriate action
- Stabilise distillation system to produce specified rate and quality within minimum time.
- Monitor distillation process.
- Continually monitor process systems to ensure that product specifications are maintained
- Minimise the risk of product specification deviations during the process by applying process knowledge
- Adjust process variables to ensure the product remains within specification
- 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
- Record product movements as a historical record of the quantity and quality of the finished product.
- Change production rates and/or product specification.
- Predict the need to make change to meet process requirements
- Manipulate unit temperatures to achieve product specifications
- Trim plant in a manner which prepares it for the transition
- Manage transitions smoothly and in a timely manner
- Minimise out of specification material as a result of a transition.
- Shut down distillation systems.
- Determine type of shut down required
- Give advanced warning of shut down where possible
- Change over individual items of equipment
