Implementing the Green Batch: A case study: Continuous statistical evaluation to achieve the most energy efficient and reliable process

Abstract

Manufacturers often experience different process performance from one batch to the next on the same equipment in the same process (e.g. energy use, lead time and downtime). In most cases, poor energy performance of a batch process is analysed retrospectively, and the root cause of the decline in performance/output must be manually identified In the concept of the Green Batch, process performance is continuously monitored against a best-performing batch. This paper proposes a methodology for implementing the Green Batch on an existing process.
