This paper examines the basic requirements associated with batch analytics applied for on-line operation. It delivers basic principles of the data processing and user interface for the application of on-line analytics to a batch process. It explains how to achieve proper data alignment for different batches, a key requirement for building good statistical models, and how to use the model for on-line analysis. It outlines the analytics prototype field test results for specialty chemicals batch process. The process simulation referred to the paper illustrates the operation basics and can be accessed through the web interface.
