Determine process loss through mass or energy balancing

This unit of competency covers the analysis of a process to determine loss of resources by the application of the first law of thermodynamics (more commonly known as mass and energy balancing). It includes the selection of mass or energy balancing or both as appropriate to the type of processes being examined and may be applied to an entire process, part of a large process, or part/all of a value chain.

Application

This unit is a Vocational Graduate Certificate unit and follows the AQF guidelines for such units in that it assumes an entry qualification, such as:

an Advanced Diploma or Diploma in sustainability or relevant technical field

a Bachelor Degree in a relevant technical field

other relevant higher education qualifications, often with relevant vocational practice

relevant extensive vocational practice, without formal qualifications but which result in appropriate entry level skills.

This unit covers the analysis of a mass (material) and energy (usually heat or motive force) flows through a process to determine overall mass and energy efficiency, losses which occur through the process and how much loss occurs in each part of the process. This is achieved by the application of the techniques of mass balancing, energy balancing and combined mass and energy balancing. The application of this unit is especially suitable where high volumes of materials or large amounts of energy are used in a production process. The unit may also apply to other large energy or materials use processes in the value chain, such as logistics and transport.

This unit will lead to the identification of parts of the process which have the greatest resource loss/lowest resource use efficiency and so provides the basis for eliminating or reducing this loss and improving this efficiency. It does not include the implementation of that response (see MSS017004A Lead sustainable strategy deployment).

This unit would typically be undertaken by a manager or senior technologist who has significant responsibility for sustainability in their work role.

Skills covered by this unit may be applied individually or in a team context.

Evidence Required

Overview of assessment

A person who demonstrates competency in this unit must be able to analyse processes or part or all of a value chain using mass and/or energy balancing as appropriate.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently apply the skills covered in this unit of competency in new and different situations and contexts. Critical aspects of assessment and evidence include:

undertaking a mass and an energy balance (which may be on different systems) or a combined mass/energy balance

identifying appropriate responses

communicating the above as appropriate

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or a simulated workplace environment.

Assessment should emphasise a workplace context and procedures found in the candidate’s workplace.

This unit of competency may be assessed with other relevant units addressing sustainability at the enterprise level or other units requiring the exercise of the skills and knowledge covered by this unit.

The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.

Method of assessment

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work-like environment.

Guidance information for assessment


Range Statement

Sustainability

Sustainability incorporates the three aspects of:

survival of the ecology/physical environment (to manage the impact of the business to ensure the survival of the physical environment)

economic viability (efficiency, cost and waste reduction and competitiveness to support survival of the business)

social sustainability (to manage the impact of the business to ensure its continued survival within the community and the survival of the community)

System

A system is that process, or part of a process, which has been selected for analysis. It includes all the steps in the process which fall within the defined boundary. These steps have been referred to as ‘sub-systems above. The system may be any part of the value chain or the entire value chain

Sub-system

A sub-system is part of the system which may be chosen for separate analysis or study

Portion of the value chain

Value chain is the sequence of activities that a firm undertakes to create value/product (good or service). Portion of the value chain includes:

sections internal or external to the organisation

Mass/energy balancing

Mass balancing is an analysis technique which allows for the calculation of mass flows and consumption through a process and losses of mass from the system/product

Energy balancing is an analysis technique which allows for the calculation of energy flows and consumption through a process and the losses of energy from the system/product

Mass and energy balancing may be undertaken as separate activities or in some circumstances as a combined mass/energy balance

Appropriate response

Appropriate response includes:

application of the hierarchy of hazard control to sustainability hazards

when the impact cannot be prevented application of mitigation and amelioration techniques, such as:

capture and storage (e.g. scrubbing) and similar ‘end of pipe’ solutions

dilution/dispersion and similar techniques which reduce concentration but not amount

other approaches which meet the sustainability requirements
