DISTRIBUTED CONTROL SYSTEM (DCS)

DISTRIBUTED CONTROL SYSTEM :

Distributed control systems (DCS) are dedicated systems used in manufacturing processes that are continuous or batch-oriented. Processes, where a DCS might be used, include Chemical plants. Petrochemical (oil) and refineries.

Why DCS is called Distributed Control System?

As the name implies, the DCS is a system of sensors, controllers, and associated computers that are distributed throughout a plant. Each of these elements serves a unique purpose such as data acquisition, process control, as well as data storage, and graphical display.

The basic elements comprised of a DCS include an engineering workstation, operating station or HMI, process control unit or local control unit, smart devices, and communication system.

A distributed control system (DCS) is a platform for automated control and operation of a plant or industrial process. A DCS combines the following into a single automated system: human machine interface (HMI), logic solvers, historian, common database, alarm management, and a common engineering suite.

THEORITICAL YIELD VS ACTUAL YIELD

Image
THEORITICAL YIELD VS ACTUAL YIELD : Amounts of products calculated from the complete reaction of the limiting reagent are called  theoretical yields , whereas the amount actually produced of a product is the  actual yield . The ratio of  actual yield  to  theoretical yield  expressed in percentage is called the percentage  yield
