DPSIM (Dynamic Process Simulator) is a process simulation software platform developed by EPM for the modelling and simulation of mineral processing systems.[1]

The software uses flowsheet-based simulation in which material streams connect mathematical models representing mineral-processing unit operations. Its model framework includes operations such as crushing, screening, grinding, classification and flotation, and can represent particle-size distributions and multiple material components.[1]

DPSIM includes both steady-state and time-dependent simulation approaches. A free public version, known as the DPSIM Static Module, is intended for steady-state mineral-process simulation, while dynamic simulation, process-control and reliability-analysis capabilities are part of the full DPSIM platform.[2][3]

Simulation framework

DPSIM represents a mineral-processing plant as a flowsheet composed of interconnected material streams and unit-operation models. Material properties are transferred between models as the flowsheet is calculated.[1]

In steady-state simulation, the flowsheet is iteratively calculated until the process variables converge. The resulting solution represents the process under fixed operating conditions.[4]

For dynamic simulation, process conditions evolve through a sequence of time steps. Variables such as feed rate, equipment conditions and operating parameters can change during the simulation, allowing the response of the flowsheet to disturbances and operating actions to be evaluated.[4]

Static Module

The DPSIM Static Module is the publicly available steady-state version of DPSIM. It is designed for creating mineral-processing flowsheets, calculating material balances, examining stream properties and using mathematical models of mineral-processing equipment.[2]

The module includes a public model-reference library describing the mathematical basis, parameters and outputs of selected unit-operation models.[2]

Examples of models documented in the library include population-balance grinding models and empirical crushing models.[5][6]

Dynamic simulation

The full DPSIM platform supports time-dependent simulation of mineral-processing flowsheets. The simulation framework allows different modelling approaches to be used depending on the unit-operation model, while process conditions and operating logic are evaluated over simulation time.[4]

The dynamic environment includes tools for representing changing operating conditions, control logic, equipment states and process disturbances.[4]

Reliability analysis

DPSIM Full also includes workflows for reliability and production-availability studies. Equipment failure and repair events can be combined with material inventories, equipment states, standby logic and operating rules to evaluate their effect on plant production.[3]

The reliability framework can represent parameters such as mean time between failures (MTBF) and mean time to repair (MTTR), as well as buffers including stockpiles, bins, tanks and sumps.[3]
