DESIGN, SIMULATION AND IMPLEMENTATION MONITORING SYSTEM FOR SYSTEM CONTROL C4 FEEDING PUMP FOR FEED VAPORIZATION IN THE BUTADIENE PLANT

Abstract

This study implements the auto start control system on an electric motor 3 phase C4
Feeding pump when the discharge pressure is low-low (4.3 kg /cm²). The C4 feeding pump
motor was initially manually operated from the local control station, this was very ineffective
and inefficient because it still relied on the field operator to operate the pump motor and when
the plant was in normal operating it is very risk if the field operator late to operate motor then it
will impact to quality of the product, and if the delay time to operate motor is too long then plant
have to shut down, therefore improvement is needed in the C4 feeding pump motor control
system. In this paper, various types of 3-phase motor control are explained which allow it to be
applied to the C4 feeding pump motor that are on-off, inverter, and variable speed drive and
efficient selection of the three systems control of the motor. Software and hardware used in this
thesis work are DCS CENTUM VP Yokogawa.
