There is a control system for the preparation of the end products obtained by blending. It is prepared as per the standard recipe specifications. These recipe specifications are set in the control system. Then the DCS (distributed control system) operates the specified pumps to keep the product meeting requirements. There are different advantages and disadvantages concerning DCS. DCS properties and operations vary from vendor to vendor. But the basic concept remains the same. This topic will discuss DCS-based recipe control, typical/advanced functionalities, ramping, pacing, a roadmap to RBC operations, recipe selection, pumps usage history/selection, auto blend lineup, blend status, control and status monitor, analyzer status, blend monitoring, the additive injection system, current blend/ final blend/screen reports, etc.
