This unit of competency covers the skills and knowledge required to operate a reaction system which forms an integral part of a production process. The reactor and its control will be relatively simple, operated in a stand-alone manner. The reaction may, or may not, include the use of catalyst (either homogeneous or heterogeneous phase). The vessel in which the reaction is occurring may be a purpose built 'kettle' or other reaction vessel or it may simply be a stirred tank. These are typically found in small batch plants, although appropriate examples might also exist in larger plants. Processes may be batch or continuous.This unit of competency applies to operators who are required to monitor the reactor operation, make adjustments to process or product properties as directed or to procedure and identify operational problems and take appropriate action.This unit of competency applies to an individual who may work alone although under routine direction and supervision. They may work as part of a team or group and will work in liaison with other shift team members and the control room operator, as appropriate.This competency does not cover operating a control panel. Where this is required the appropriate control unit should be used.No licensing, legislative or certification requirements apply to this unit at the time of publication.
