Flowsheet Management (Triple Bottom Line)

Flowsheet is at the core of any chemical and metallurgical business. It defines how the economic value is created by transforming chemically and physically raw materials into saleable products.

How effectively the flowsheet is managed to sustain the economic value over time defines the competitive advantage of the metallurgical and chemical operations in the 21st century knowledge economy

What is a Flowsheet?

It is a sequenced conversion of raw materials chemically (unit process) and physically (unit operation) into desired products at highest possible margin.

How well do you know if you can differentiate between your unit processes and unit operations?

Why use a Flowsheet?

A flowsheet defines the requirements (quality, quantity, price) for all the resources required to transform the raw materials into final products.

Companies aspire to improve their effectiveness in the management of every resource, but what about the flowsheet as the key competitive resource and advantage of the company?

How effectively are your chemical & metallurgical operations set up to manage the flowsheet and the value it is designed to create? 

Flowsheet Challenges

Metallurgical Operations around the world face ever-increasing num ber of challenges that impact the effectiveness of their flowsheet designs

High operating costs (labour, transportation, power)

Increasing regulatory and societal pressure for environmental stewardship

Increasing requirement for resource efficiency and recycling to meet environmental and economic objectives

Increasing complexity of recycling material types and life cycle management challenges

Multiple sources of feeds that require better logistics and blending

More complex feeds with more impurities, but better margins

Need for more complex metallurgical flowsheets to process “impure” feeds

Shortage of qualified metallurgical personnel (retirement, industry availability)

Tougher product specification (quality) set by customers

Is your business impacted by these chemical & metallurgical flowsheet challenges?

Sustainable Flowsheet: Triple Bottom Line Management

Social Sustainability

Maintain the social license to operate the flowsheet by:  

  • continuously evaluating the intention of key social license holders to support the changes to the flowsheet
  • identifying the gaps in the social license to operate the flowsheet as designed
  • implementing actions to achieve positive level of support from all the social license holders
Economic Sustainability

Maintain or increase the growth rate of the flowsheet’s margin / profitability by:

  • minimising the deviations from the designed chemical & metallurgical performance of the flowsheet
  • optimizing the flowsheet design to scale up metallurgical constraints and reduce the cost of processing
  • introducing new unit operations / processes to process new “dirtier” / higher margin feeds and products
Environment Sustainability

Maintain the environmental license to operate the flowsheet by:

  • complying with ever-tightening environmental regulations
  • reducing designed and actual environmental footprint and waste generated by the flowsheet while processing “dirtier” feeds
  • maintaining positive level of support from all the environmental license holders

Flowsheet Management

A set of organisational processes and tasks to be performed which impact critical value drivers which enable flowsheet challenges to be managed. These will deliver a sustainable margin growth rate, whilst maintaining social license to operate the flowsheet, and reducing environmental impact.

Flowsheet Performance

Flowsheet is economically viable and sustainable, if “Margin” indicators are more stable over 5 years than “Lost Opportunities” indicators

By measuring the “loss” or “exceeded margin” indicators to show the gaps in how a company manages its flowsheet, will result in the opportunities to improve the value the flowsheet can generate.

Flowsheet Value Drivers

To improve the flowsheet performance and increase or and sustain the value created by the flowsheet, it is critical to understand the factors that drive the “flowsheet margin” and reduce “flowsheet losses”.

FLOWSHEET MARGIN

Establish and increase the economic margin that Flowsheet is designed to generate

Designed Performance Capacity Processing Cost Feeds Blending Recovery
FLOWSHEET RELIABILITY

Reduce deviations from Flowsheet Designed Performance including losses of unwanted events

Control Critical Control Management Reliability Analytics Operator-driven Flowsheet Reliability
FLOWSHEET ROCE

Optimise the Flowsheet Design, Control & Perfromance and increasing ROCE

Benchmarking Optimisation Strategy EPCM Chemical & Metallugical Readiness
SUSTAINABLE FLOWSHEET

Reduce emission footprint and waste of resources generated by Flowsheet, maintaining social license to operate.

Emission Footprints Waste of Resources Social License to Operate
FLOWSHEET EXCELLENCE

Improve the standard of chemical and metallurgical work, its reliable delivery in comparison to the competitors

Standardisation Capability Audit
FLOWSHEET DIGITALIZATION

Employ digital technologies to transform the nature of chemical & metallurgical work to improve flowsheet process effectiveness

Control Digitalisation Analytics Digitalisation Flowsheet Data Reliability Flowsheet Information Management Digital Flowsheet

Flowsheet Management Capability

Flowsheet Management Capability of an organization is the capability to perform effectively the tasks that impact the flowsheet value drivers to continuously increase and sustain the value generated by the flowsheet.
