Learning Outcomes and Application | This unit of competency covers the skills and knowledge required to determine mass transfer loads and flow rates. 'Flow rate' and similar terms refer to the flow rate in terms of kg/h, or kg/batch or similar conceptual flows.This unit of competency applies to activities which aim to resolve identified plant or process problems, such as improving materials efficiency or specification of new or modified equipment.This unit of competency applies to any mass transfer mode, including mass flowdensity variations with changes in temperature (and pressure where appropriate)simple (physical) mixingsimple (physical) separationchanges in component mass flow rates due to chemical reaction (including mixing and separation using chemical reaction).This unit of competency applies to senior technicians or those in similar roles who are required to calculate mass transfer and change in mass contained for a plant item/plant area in order to determine mass transfer efficiency or losses from/gains to the system. It may require the determination of the yield from a chemical reaction. This may be done as a step to improve efficiency, for plant/process design/improvement or other reasons.No licensing, legislative or certification requirements apply to this unit at the time of publication. | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. The unit should be assessed holistically and the judgement of competence based on a holistic assessment of the evidence. The collection of performance evidence is best done from a report and/or folio of evidence drawn from: a single project which provides sufficient evidence of the requirements of all the elements and performance criteria multiple smaller projects which together provide sufficient evidence of the requirements of all the elements and performance criteria. A third-party report, or similar, may be needed to testify to the work done by the individual, particularly when the project has been done as part of a project team. Assessment should use a real project in an operational workplace. Where this is not possible or practical, assessment must occur using a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills. Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept). Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate. Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit. The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed. Foundation skills are integral to competent performance of the unit and should not be assessed separately. Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator. In addition, the assessor or anyone acting in subject matter expert role in assessment must demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they must assess with a subject matter expert who does meet these requirements. Technical competence can be demonstrated through one or more of: relevant VET or other qualification/Statement of Attainment appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions Currency can be demonstrated through one or more of: being currently employed undertaking the type of work being assessed being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment conducting on-the-job training/assessments of the type of work being assessed being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work. |
