Control and instrumentationMaintaining the pressures, temperatures, level and the flow in the various tanks,

pipes and also in the various heat exchangers present in the plant.

Alarm generation in case of failure of any equipment.

There are numerous equipments in the plant and all their readings are maintained by C & I department. For this purpose softwares like PI(Plant Info) system,SAP etc. are used.

Various electronic instruments such as electronic sensors, actuators and controllers are used to take the readings of the equipments.

Measurement and display of various parameters is done by converting the signals from equipments to digital form.

All purchasing,installing and maintenance of equipments comes under C & I Dept.

The main work of C & I department is to observe ,control and manipulate electrical as well as non-electrical quantities like temperature, pressure, vibrations etc.
