The client wanted to increase the average rate of their Fixed Plant from 1,670tph to 2,850tph (an increase of 71%) and wanted to know how this could be achieved with minimal capital outlay and whilst maintaining the required quality specifications
This information would be used to develop the business case for the expansion
Our team built and validated a base case model in LIMN and then developed and modelled alternative flow sheet options required to achieve the additional rate
The project used the following methodology 1. Consolidate Equipment Information, 2. Variability Assessment of the Process 3. Base Case Model Development, 4. Feed Size Distributions and Model Validation, 5. Future State Flow Sheet Development and 6. Future State Flow Sheet Modelling.
4 alternative flow sheets were collaboratively developed and modelled using LIMN
An equipment specification sheet for each of the 4 flow sheets was developed
The equipment specification sheets were used to cost the proposed expansion and develop the business case
