Analisis dan Simulasi Shell Heavy Oil Fractionator (SHOF) Menggunakan Metode Kontrol PID
ABSTRACT: Shell Heavy Oil
Fractionator (SHOF), types of distillation columns are often used as models in
the application of advanced control, are examples that illustrate the dynamics
of real plant from the process industries, especially petroleum refining
industry. This thesis research analysis and simulation of control systems Shell
Heavy Oil Fractionator column (SHOF) which is a multivariable system with three
inputs and three outputs (Multi Input Multi Output). Interaction between
subsystems is reduced by applying the method of Relative Gain Array and
decoupling, so the system can be transformed into three Single Input Single
Output (SISO). Control system uses Proportional Integral control (PI) and
Proportional Integral Derivative control (PID). SHOF control system simulation
can be concluded that decoupling eliminate the influence of input Top Draw on
outputs Side End Point Composition and Bottom Reflux Temperature, influence of
input Side Draw on outputs Top End Point Composition and Bottom Reflux
Temperature, as well as the influence of inputs Bottom Reflux Duty on outputs
Top End Point Composition and Side End Point Composition. The best results were
obtained from the Top End Point Composition control using PID control
Chien-Regulator 1, Side End Point Composition using PI control Minimum
IAE-Murill Regulators, and the Bottom Reflux Temperature using PI control with
closed loop time constant (Tcl) for 1.5 minutes.
