Abstract

Operator training simulators (OTS) are widely used in several industries including chemical processing, oil and gas, medicine, aircraft and nuclear facilities. However, developing a biorefinery OTS is a complex engineering design activity that requires a structured technique. This paper presents a structured methodology that applies design frameworks from other disciplines and a user-centred approach for biorefinery OTS design. These include the definition of end user requirements (operator training needs), and the analysis of these requirements using Quality Function Deployment (QFD). Furthermore, an algorithm for bioprocess optimisation and automatic adjustment of operating parameters is developed for integration into the OTS. This algorithm is based on the Nelder-Mead simplex method for multi-dimensional function minimisation. Identified user requirements were categorized into primary, secondary and tertiary training needs, with increasing levels of detail from primary to tertiary needs. The relationships between identified operator training needs and OTS technical and functional specifications were investigated, and a priority rating assigned to the most important OTS specifications. Identified OTS specifications were evaluated for robustness to ensure that important features were not omitted from the final design.

Summary

Introduction

As the search for more efficient ways to produce bioethanol and other biofuels such as biodiesel and biogas intensifies, there is a responsibility to provide fitfor-purpose education for the generation of bioengineers and the right skill and training for process operators who will run the biorefineries required to meet the energy challenges of today. Developing a fully functional biorefinery Operator Training Simulator (OTS) is a complex activity, both in terms of the technical requirements and time needed for completion. A systems engineering approach is required to facilitate the OTS development process. This approach ensures that the OTS design activity is completed in a structured and systematic manner. The process is usually iterative and involves system definition, synthesis, analysis, design, test and effectiveness evaluation. Another key element of this process is the integration of different subsystems in a manner that ensures compatibility and optimum performance of the final design.
